THE PHARMACEUTICAL JOURNAL AND TRANSACTIONS. 
[October 7, 1S71. 
THE EXHIBITION AT THE EVENING MEETING. 
In. accordance with the intimation of the Council of 
the Pharmaceutical Society as to the exhibition of any 
articles of novelty, or otherwise, of special interest to 
pharmacists on the occasion of the Inaugural Meeting of 
the session, a space was set apart in the Society’s mu¬ 
seum for this purpose. Some of the articles exhibited 
were exceedingly interesting. 
A principal feature was the exhibition of the donations 
presented to the museum since the last meeting of the pre¬ 
vious session, a list of which will be found at p. 287. 
Prominent among these were the collection of Chinese 
materia medica, of more critical value than such collec¬ 
tions usually are, since it includes the identical specimens 
described in Dr. Porter Smith’s work recently noticed 
in this Journal; a few specimens of Indian drugs, prin¬ 
cipally officinal in the Indian Pharmacopoeia; and the 
specimens of oil and carbolic acid from Andromeda 
Icschenaultii , prepared by Mr. Broughton. There was 
also a specimen of the much-lauded and much-abused 
condurango. 
A specimen of the impure fuming chloral hydrate re¬ 
ferred to by Dr. Versmann in his communication to this 
Journal last week, was exhibited by that gentleman; 
also specimens of the purified salt in crystals. 
Mr. "Williams sent for exhibition one of Fletcher’s 
Blowpipe lamps, manufactured by Messrs. Horne and 
Thointhwaite. In this the flame is delivered from a 
horizontal pipe, round which is coiled a small iron tube, 
ending at the mouth of the gaspipe. Through this air 
is blown, which is heated in its passage by two small 
Bunsen jets beneath. 
A Compound Hydraulic Press, suited to small labora¬ 
tories, for extracting tinctures, etc. and for all purposes 
where hydraulic pressure is required (Desgoffe’s patent), 
was exhibited by Messrs. Hayward Tyler and Co. 
The press is provided with a circular table, round 
which is a groove conducting to a small spout in front. 
On this table is placed a galvanized iron double box, 
box has been charged, the pressure is first applied with 
the screw. If moderate pressure only is required this 
will be sufficient; but if great force is to be used the 
hydraulic press is put into action. This consists of a 
ram 4 in. in diameter, which raisesjthe table against the 
mullet. Below the 4 in. ram, and entering the same 
chamber in which it works', is a second ram, about 
13j in. diameter, forced inwards by a screw and hand, 
lever. As this enters the chamber it will be seen that, 
on the principle of the hydraulic press, it displaces the 
water, and forces out the press-ram. A pressure of six 
tons is stated to be easily obtained, due to the difference 
in the diameters, multiplied by the power of the screw. 
The advantages claimed are, that there are no valves to get 
out of order, and that the power is applied continuously. 
Messrs. Maw, Son and Thompson exhibited several 
articles. Pindar’s pill machinery attracted considerable 
notice. It consists of a “piping press,” into which 
the pill mass is placed and forced by screw pressure 
through holes in the bottom in long pipes, and a rotary 
machine consisting of two grooved cylinders, through 
which the “ pipes ” are passed and fall into a tray below 
in a pilular form. The registered stopper-guard consists 
8 in. diameter by 10 in. deep (shown standing by the side 
of the press), the inner casing being perforated with 
holes. The movable mullet of the press, worked by a 
powerful screw and hand-wheel, fits accurately into this 
box, and travels nearly its whole depth. When the 
of an india-rubber ring passing round the stopper, and 
fastened by a brass clip to the lip of the bottle, as shown 
by the accompanying engraving. Other objects were a 
gas furnace, designed by Mr. T. B. Groves, in which the 
burners are so arranged as to give a great range of tem¬ 
perature, some Bunsen burners fitted with trivets, a label 
damper, and a powder-folding apparatus fitted with a 
ratchet by which it can be adapted to any size required. 
Messrs. Maw and Co. also exhibited one of Young’s 
Poison Cabinets, described in this 
Journal, Vol. I., p. 876. 
Messrs. Frazer and Green exhi¬ 
bited a bottle-guard designed by 
them. It consists of wire-work 
which fits over the bottle, so that in 
the event of its bursting while bot¬ 
tling waters, the glass is retained 
inside the wire casing. They also 
exhibited some poison bottles, the 
distinguishing features in which are 
the colour and the word “poison ” 
pi*inted beneath the label. 
Messrs. Kay Brothers, of Stockport, exhibited a new 
oil-bottle invented by Mr. Sagar, the advantage claimed 
for which is that it is so constructed that every drop of 
oil runs back into the bottle, and thus avoids the waste, 
mess and dirt which attend the old bottle on the shelf.
