IT WAS Huxley who reminded us that science is nothing but trained and organized
common sense. That this uncommon commodity is often lacking in the investigation
of alleged abnormal phenomena is only too apparent to those engaged in serious
psychical research. The work of great psychists like Barrett, Crookes and Richet
is convincing only because we know that their methods and records are those of
the trained and scientific worker. The most convinced spiritualist will, I am
sure, be the first to admit that much of the work of the old-time investigators
is valueless owing to the inadequacy of their methods and the incompleteness -
or total lack of -detailed records. Some spiritualists affect to despise the
scientific side of the subject, but it is noticeable that whenever their leaders
wish to appear convincing, either on the platform or in print, they invariably
fall back on the scientist and scientific experiments for their proofs and
evidence. Even the Roman Catholic Church is not averse to the scientist putting
his cachet on the miracles of Lourdes and similar manifestations. In a speech(1)
the Pope said that the Church did not fear scientific investigation with regard
to miracles; on the contrary, such help was welcomed.

Founding of the National Laboratory of Psychical Research
At the close of the Great War it was obvious that something would have to be
done to combat the machinations of the horde of charlatans who were battening on
the bereaved, the credulous, and the uncritical. To this end, I decided to
establish a laboratory in London where the miracle-mongers could be tested and
the genuine medium encouraged. The main object of the laboratory was to
investigate in a dispassionate manner, add by purely scientific means, every
phase of psychic or alleged psychic phenomena - uninfluenced by the emotionalism
of spiritualism on the one hand, and the 'philosophic doubt' of the orthodox
scientist (especially the physicist) on the other. It was decided to place the
evidence obtained, whether good or bad, before such members of the public as
were interested in the subject. Starting with no preconceived
theories - scientific, philosophical, or religious - the Council of the Laboratory
endeavoured to ascertain and demonstrate the laws underlying psychic or abnormal
manifestations. Personally, I was determined to bring psychical research to the
notice of orthodoxy, and my great ambition was to establish a department of
psychical research at London University.
The first work of the Laboratory was carried out in 1923, in a house in Queen
Square, Bloomsbury. The first 'subject' was Miss Stella C., whose phenomena made
psychic history(2). During the examination of this young woman it was found that
our equipment and apparatus were not sufficient for the many experiments we
wished to carry out, and I decided to lease a suite of rooms which I could fit
out with every scientific and automatic recording instrument which experience
suggested might be useful to us. I found suitable accommodation in Queensberry
Place, South Kensington, and on January 1, 1926, we opened the doors of the only
properly-equipped psychic laboratory in the world to those researchers who cared
to use it. The apparatus, furniture, instruments, tools, etc., were valued at
£3,000. In February, 1931, the Laboratory was moved to larger premises at 13
Roland Gardens, South Kensington, where it remained until March, 1937, when,
upon the termination of our lease, the equipment, library, etc., were
transferred to the University of London.

For the guidance of those who wish to establish university departments of
psychical research, some account of the rooms and equipment of the National
Laboratory (now the University of London Council for Psychical Investigation) is
The Laboratory suite comprised the following rooms: office, chemical and
physical laboratory, séance-room and library, dark room, workshop, large hall,
and usual domestic offices. (See Plate XIV.)
The séance-room. measured 22 feet 7 inches long, by 15 feet 7 inches wide, by 9
feet 9 inches in height. It had two doors, one leading into the workshop, the
second giving access to the entrance hall. Both of these doors could be locked
One of the recesses formed by the chimney-stack was extended, on the ceiling, by
means of a semi-circular rail, and from this rail was suspended by means of
pulleys and roller-bearings a pair of red plush curtains weighing 14 pounds.
This formed the traditional 'cabinet,' roomy and comfortable, in which a medium
could sit in an arm-chair, the curtains completely concealing him. The
measurements of the cabinet were: width, 6 feet 3 inches; height, 9 feet 9
inches; depth, 3 feet 3 inches, depth of sides, 2 feet.
The floor of the séance-room (in common with the other rooms of the Laboratory)
was covered with three-eighths inch natural cork carpet, which is a bad
conductor of heat, and thus keeps the room at an equable temperature. The cork
is pleasant to the feet and clean, and forms a good background for anything that
may form there.
The lighting arrangements were somewhat elaborate and every provision was made
for various forms of illumination. Ultra-violet and infra-red installations were
available and X-ray apparatus was at hand, if necessary. The normal white
lighting was by means of a central pendant holding two 100-watt bulbs. By the
turn of a switch, these could be converted into bright ruby illumination,
supplied by two 25-watt red bulbs. This light was useful for photographic work
during a séance.
The illumination of a séance could be accomplished in many ways, and by various
flood-lights, including coloured filters or screens in special 'lanterns' or
inverted ceiling lights constructed by the Wratten Division of Messrs. Kodak,
Ltd. The entire series of Wratten filters or 'safelights' were employed in two
sizes, 12 x 10 inches, and 10 x 8 inches. The most commonly used were: Series 0,
pale orange; series 1, deep orange; series 2, deep red; series 3, a special
'neutral' light, a combination of orange and green tints, which we used for
panchromatic or autochrome plates, or cinematographic films. By using a 60-watt
new gas-filled electric bulb with each of these flood-lights and filters, it was
possible to keep constant and to standardize the lighting of a séance, so that
the exact illumination could be duplicated at future experiments. All these
lights were controlled by rheostats or dimmers. Six lighting plugs and two power
plugs were available for the various lamps and instruments.
For heating the room,. a 1,000-watt electrical radiator, with enclosed elements
which converted water into superheated steam, could be used, the fins heating by
convection. A thermostat automatically regulated the heat, which thus remained
constant. The séance-room also contained a fireplace permanently blocked by a
metal plate and a large gas-fire. A large window at one end of the room could be
screened by an opaque, black rubberized spring blind, the edges of which were
masked by a felt-lined 'box' which entirely surrounded the window. These spring
roller-blinds are used extensively for X-ray work in large hospitals. The system
is an ideal one for a séance-room which can be made absolutely dark in a few
A number of photographic and cine cameras, dictaphones, time-clock, etc., were
at hand for recording purposes and a cabinet gramophone and musical boxes
supplied such music as was required by the medium. Bookcases lined the walls of
the room (giving the place a homely and comfortable appearance), and the usual
chairs, table, etc., were available for the sitters. A large settee was used for
experiments in hypnosis. A special teak note-taker's table, on pentagraph rubber
wheels, supported dictaphones (for recording or note-taking), rheostats,
luminous watch for timing, etc. Transmitting thermographs, barographs, and other
instruments were installed for recording the meteorological conditions. A
special instrument which I adapted for séance purposes is a time-clock which
indicates the exact duration of a phenomenon. The system is an electrical one.
The movement of a special 24-hour clock is so constructed that a red bulb is
caused to glow at regular intervals, of 1/2, 1, 2, 3, 4 or 5 seconds, according
to the setting. By the turn of a switch a buzzer or bell can be operated instead
of the light. By placing the clock in a convenient position in the line of sight
of a person noting the manifestations, the precise duration of a phenomenon can
be accurately determined. A special note-taker's lamp reflected a red light from
below through the paper which was being written on, no extraneous light escaping
into the séance-room. Another special piece of apparatus was the fraud-proof
double cage table, used for testing telekinetic mediums.
Chemical and Physical Laboratory
The laboratory belonging to the organization was a well-lighted front room, 17
feet 4 inches by 16 feet 4 inches, with two large windows. Wall benches round
all four sides of the apartment, with cupboards beneath, afforded excellent
working space for experiments. Bunsen and other gas-burners were attached to
connections at various points. Batteries of electric bulbs could be used to
regulate the lighting of the room, and power and lighting plugs were spaced
round the walls at regular intervals. Over the benches were shelves for bottles,
instruments, etc. A 4 feet 6 inches square teak laboratory table and six chairs
completed the furniture. The laboratory could be converted into a large dark
room by erecting special shutters, impervious to light, over the windows.
Every chemical likely to be required in photography or psychical research was
available, and we were the happy possessors of several pounds of radio-active
red, green, and yellow sulphide of zinc (which I purchased from Poulenc Freres
of Paris), used for making luminous paint. Our stock probably exceeded that held
by any institution in Great Britain. Glass-blowing apparatus, laboratory
glass-ware, graduated measures, and the hundred-and-one pieces of apparatus
which go to make a well-equipped laboratory were to be found in our rooms.
The special equipment of the laboratory included an electric heater for melting
wax, etc., chemical balances, electroscopes, galvanometers, barographs,
thermographs and other thermometers for measuring temperatures, a fraud-proof
control for 'voice mediums,' an air-tester for recording the circulation of the
air, and an extensive broadcasting equipment complete with microphones. A large
copper still provided all the distilled water needed for photographic and other
purposes. An assortment of luminous objects, musical toys, isolation chambers
(for telekinetic phenomena) and other special apparatus (such as were used for
the Marion experiments in hyperaesthesia(3)) were kept in the laboratory. For
photographic purposes, a 500-watt spotlight, with filters, and a 1,000-watt
flood-lamp were used. For photographing in a dull light, infra-red lamps and
filters (for use with infra-red films and plates) were employed. For
ultra-violet illumination, a quartz mercury-vapour lamp, in special steel
cabinet, with window for filters, was erected. For certain experiments, complete
X-ray apparatus was installed and there were two battery-chargers (for both A.C.
and D.C.). Automatic flash-light apparatus and Vaku-Blitz bulbs were used for
photographing during a séance.
(3) Illustrated in Confessions of a Ghost-Hunter (Plates opposite pp. 266 and
The optical equipment of the laboratory was particularly complete. There were
fifteen cameras of various sizes, including stereoscopic, reflex, and
cinematographic. These last-named included Zeiss 35-mm. and Bell and Howell
16-mm. instruments, together with their respective projectors, and reeling and
splicing equipment. Three photographic enlargers (one vertical automatic)
belonged to this section. Five stereoscopes (including a semi-automatic 'Taxiphote'
instrument for 45 X 107 mm. positives) by Zeiss and other makers were in the
The Laboratory possessed four microscopes (binocular and monocular) with
batteries of Zeiss and Leitz oculars and objectives (including apochromatic), an
automatic microtome for cutting sections, and the usual mounter's cabinet,
lamps, specimen cabinets, etc., used in microscopy. Some interesting discoveries
concerning the composition of 'teleplasm' were made with these instruments(4).
(4) See 'The Microscopic Anatomy of the Albuminoid Type of Duncan "Teleplasm",'
by Harry Price, Bulletin 1, Nat. Lab. Psychical Research, London, 1931, pp.
For our lectures and demonstrations, both cine projectors and optical lanterns
were used. The latter included an 'Optiscope' (a perfect instrument with many
refinements) and an epidiascope for projecting pictures of solid objects. The
necessary silver and other screens were, of course, part of the equipment. Many
other optical instruments were used from time to time, and for 'scryers' we had
five crystals, including a 5-inch flawless quartz sphere, true in every diameter
to .001 inch.
Workshop and Dark Room
The uninitiated, when viewing for the first time the workshop attached to the
laboratory, often expressed surprise that tools could possibly be used in
psychical research. When it was pointed out to them that the construction,
maintenance, and repair of apparatus, instruments, cameras, electrical
equipment, etc., needed every kind of tool, they realized the utility of the
workshop, which was in almost daily use.
The workshop attached to the laboratory contained every tool and gauge necessary
for the construction and maintenance of scientific apparatus. Turning, brazing,
casting, forging, grinding, polishing, etc., could all be carried out in the
workshop by a competent person. Two lathes were installed. The larger, a 4
1/2-inch screw-cutting model, with 6-foot gap bed, was capable of handling
really big work. It could be driven by power or treadle. The smaller tool was a
'Lorch' lathe for fine precision work. Sets of wood-turning and wood-carving
tools could be used with the large lathe. Every size and type of screw could be
made or duplicated by one of the lathes or sets of stocks and dies.
The fittings of the workshop included a strong bench, three vices, and every
kind of tool. Sets of shelves and cupboards contained stocks of screws, plugs,
wire, electrical odds and ends, gauges, and new material. Gas and electric power
were installed for the forge, brazing jet, soldering stove, etc.
The dark-room contained the usual lead-lined sink; bench; various copper
electric lamps for ordinary and panchromatic photography; automatic alarm clocks
for timing development or enlargements; stocks of photographic chemicals; more
than a hundred glass and porcelain dishes and tanks; graduated measures,
automatic washing tanks and drying cupboards, exposure meters and filters;
printing frames and guillotines; stocks of plates and papers, and an automatic
lantern-slide maker. The window was screened by an X-ray spring blind running in
boxes, similar to the one in the séance-room, already described.
I must add that in connection with the National Laboratory there was a small
museum of objects used by mediums; specimens of 'teleplasm' (composed of white
of egg and similar substances); fake 'apports,' odds and ends of apparatus used
for 'phenomena,' and two dictaphone records of a 'Martian love song' and a
'Martian symphonic chant' recorded through the 'Martian medium,' Mrs. St. John
James. Other 'museum pieces' were some 'psychic lights' as used by the medium in
the Rue Christine, Ostend; a bunch of 'psychic roses' (purchased by the medium
in Edgware Road); and an assortment of mediums' 'confessions.'
The only laboratory apartment I have not described is the office, a small room
containing the usual equipment and the card catalogue of my library(5) of some
16,000 volumes on psychical research, magic, and conjuring; a collection of many
hundreds of lantern slides, negatives, and the archives of the laboratory.

I have now said enough to give the reader an insight into the scope, work, and
research equipment of the National Laboratory of Psychical Research. The
accompanying photographs will help to give some idea of the general appearance
of the principal rooms of the organization. It has been suggested that such a
full equipment is not necessary for the investigation of phenomena, but in
practice we found that every piece of apparatus, tool, etc.) was used at some
time or other, in the examination of some medium. The choice of equipment was
based on research records of the past fifty years. I drew up a list of the
instruments, etc., which should have been used - but which were not - and decided
to house them under one roof. Many mediums have failed to pass our instrumental
and scientific tests; a few have succeeded. I will now give a list of those
mediums whom I examined (and place where investigated) during my Directorship of
the National Laboratory, from 1923 until the Laboratory was taken over by the
University of London Council for Psychical Investigation on June 6, 1934.

The work of the National Laboratory was published in
Proceedings (1927-9); the
British Journal of Psychical Research (1926-9); Bulletins I-VI 0931-3); and two offprints from
Nature, July 31, 1926 and August 18, 1928 (articles by Dr. R. J. Tillyard). In addition, the following books dealing with the work done at the
Laboratory have been issued. They are all by the present writer: Stella C.
(London, 1925, and a French edition, Paris, 1926); Rudi Schneider (London, 1930,
and German and French editions, Leipzig and Paris, 1930); Leaves from a Psychist's Case-Book (London, 1933);
Confessions of a Ghost-Hunter (London and
New York, 1936. Translations appeared during 1936-7 in the following countries:
Holland, Italy, France, Switzerland, Czechoslovakia, Austria, Hungary and
Sweden). Much of the work of the National Laboratory was recorded in the Journal
of the American Society for Psychical Research, between 1925 and 1931, when I
was Foreign Research Officer of this Society. In 1935, the British Movietonews,
Ltd., produced a talking film, 'Psychical Research' (dealing with my work at the
Laboratory), for which I wrote the script.
As I have stated, in June, 1934, the National Laboratory became the University
of London Council for Psychical Investigation. This change was the result of a
formal offer which I made to the University of London. The history of this
proposal is outlined in Chapter 3.
