A large collection of surgical and medical instruments and appliances. 
Amongst enema apparatus may be noticed the pattern known as Kem 
nedy’s, both single and double action, with plated fittings. Eguisier’s 
irrigateur, with other well-known forms of brass syringe; globe pessaries 
in ivory; expanding india-rubber pessary, with syringe attached; ear 
syringe, with shield and speculum; various cases of surgical machines 
including a complete major operation case ; a set of electro-gilt midwifery 
instruments of high and exquisite finish; a set of silver catheters; 
dental and post-mortem instruments; two electro-magnetic machines, 
on the American pattern, one fitted with single and the other with double 
magnet; Labordette’s laryngoscope ; Bank’s elastic urinal, the old glass 
form with india-rubber fitting and stop valve; earthenware inhalers; 
Clark’s pulverizer ; Dr. Bichardson’s apparatus for the application of 
ether as a local anaesthetic, with electro-gilt tubes arranged with hand¬ 
ball and foot bellows. Vaginal specula, tongue depressors, ophthalmo¬ 
scopes, and breast pumps, complete the series.

Improved gas furnace, tin distillatory apparatus, and water-bath, etc., sup¬ 
pository and pessary moulds, and a new shape for spreading breast* 
plasters. 
A small and ingenious vaccinator, which has been patented. 
PoNTiER (L. Andre-Pontier), 24, Loulevart dio Temple, Paris. 
Kessler’s evaporating and distillatory apparatus, called by the inventor by 
the general name of Erorator {ex-rore). The name is scarcely happy in 
its eWee. 
Kessler’s evaporating and distillatory apparatus, consisting of a series of super¬ 
posed vessels, each connected with a refrigerator common to all and so arranged as 
to economize the whole of the heat employed and ensure the perfect condensation 
of the vapour raised, whether of water or alcohol, plain or medicated. It is further 
adapted for the inspissation of all kinds of extracts at a low temperature, for the 
crystallization of salts at fixed temperatures, and when made of platinum, for the 
distillation of sulphuric acid. 
The inventor and exhibitor having been at some pains in introducing this 
novel apparatus, we have thought it right to give the original descrip¬ 
tion. A pamphlet was also forwarded profusely illustrated. 
L’Erorateur est un'’ appareil distilla- 
toire destine a I’evaporation ou concen¬ 
tration economique de tons liquides. 
Par sa construction, il permet de re- 
cueillir les vapeurs forme'es pendant 
I’evaporation d’un liquide, et par la, il 
se prete a la distillation, car la distilla¬ 
tion n’est qu’une condensation de va- 
The Erorator is a distillatory appara¬ 
tus for the evaporation or economical 
concentration of all liquids. It is so con¬ 
structed that vapour formed during the 
evaporation of a liquid can be collected, 
and hence it may be used for distillation, 
which is but a condensation of vapour. 
From this it will be understood, that
