Carre and Co.’s ice machine, in operation, from Mr. Sheppard; and a pneu¬ 
matic signal apparatus for domestic purposes; specimens of white marble, from 
Norway, 'and silver ore, from Mr. Gisborne. Messrs. George Treble and Son, 
of Hoxton, exhibited a working model of a chemist’s shop window, showing the 
arrangement of carboys, gas, etc., and the general planning of the window en¬ 
closure, two pedestals, with sink and drainer for dispensing counters; a nest of 
counter drawers, with pill-machine, cork-squeezer, etc., combined ; and a nest of 
shelves, with clips for any size poison bottles. There was also a leech-vase, 
from Mr. Shillcock, and an improved dental chair, with footstool and pedestal, 
contributed by Mr. Ashenhurst. 
During the evening, Mr. Highley exhibited a number of photographs upon 
the screen, by means of the oxyhydrogen light in one of the rooms, while in 
another, Mr. Ansell, of the Royal Mint, showed and explained the numerous 
forms of his ingenious apparatus for detection and giving warning of the pre¬ 
sence of fire-damp in mines. Mr. Fitz-Cook excited considerable attention by 
the exhibition of results obtained by the Graphotype process, a new system of 
engraving, which is conducted as follows:—The artist makes his sketch upon 
the surface of a block of prepared chalk, using for the purpose a quick drying 
ink composed of a mixture of glue and lampblack. The drawing being com¬ 
pleted, the portions of the chalk surface intervening between the lines of the 
drawing are disintegrated and removed, to the depth of an eighth of an inch or 
so, by means of brushes of various degrees of hardness, and the chalk block is 
then hardened by being soaked in a solution of an alkaline silicate. A mould 
is then taken from the chalk block, and a type-metal cast produced from this 
mould by the ordinary processes of stereotyping, and it is this type-metal cast 
that is used to print from. In the course of the evening, Dr. Thudichum de¬ 
livered a lecture to a crowded audience, in the Lecture Theatre, and exhibited 
upon the screen specimens of the Trichina spiralis and other entozoa, both 
as mounted objects and also in the living state, the latter being taken, in the 
presence of the audience, from the back of a live rabbit previously inoculated. 
At the conclusion of the lecture, Mr. Larkin temporarily blinded every one by a 
most vivid flash of light produced by the combustion of an ounce of metallic 
magnesium in powder mixed with chlorate of potash; a flash of light which Mr. 
Debenham took advantage of to procure an instantaneous photograph of the 
audience. 
In one of the principal rooms was a large collection of medical and economic 
plants, exhibited by Professor Bentley, from the Royal Botanic Society’s Gar¬ 
dens, Regent’s Park ; some illustrations of leaf geometry from Mr. Coultas, and 
an extensive and beautiful series of models of Fungi. 
Redwood’s Patents Company, Limited, contributed a case of fresh meat pre¬ 
served in paraffin by Redwood’s process.
