EDITORIAL OBSERVATIONS. 
vessels injected and corroded. In the fourth room were the 
various kinds of shoes. 
And here we are reminded that we have forgotten to 
notice in its proper place, that adjoining the dissecting rooms 
is the forge, in which are fourteen anvils and twelve fires for 
the use of the students, with all the tools requisite for the 
shoeing of the horse. They are required to be able to forge a 
shoe, and apply it in a workmanlike manner to the foot of the 
animal ; but they practise on dead feet to acquire this know- 
ledge. To the bellows, we observed, was attached an in- 
genious contrivance, by which their bursting is prevented. It 
consists of a safety valve, which allows of the escape of the 
carburetted hydrogen gas on its becoming generated — as it 
occasionally does when fresh coals are put on, — rather than 
of its passing into the bellows and mingling there with the 
retained atmospheric air, when an explosive mixture would 
be formed. 
In the fifth room were preparations of the muscles of the 
entire animal : one being characteristic, — a man on horse- 
back ; also of the ox, and a species of antelope. The whole 
of the preparations are enclosed in glass cases, and cata- 
logued. There were, likewise, very large models of the ear, 
the eye, the lungs, the extremities of the horse, and also 
of the whole animal, the muscles of which were separable one 
from the other. Suspended from the walls were numerous 
anatomical and other drawings and engravings, and in 
appropriate compartments were specimens of the grasses 
used as food, the esculent grains, hair, wool, &c. 
An inspection of the chemical department was reserved 
for the last. This is very complete, and we were much 
gratified. On being introduced to Professor Saunier, he 
directed our attention to what was most interesting. It 
should be observed that his instructions are not confined to 
the science of chemistry, but embrace the principles of 
natural philosophy or physics, and materia medica with 
pharmacy. Most, if not all, the pharmaceutical and chemical 
compounds used in the hospital are made in the laboratory, 
which is well arranged and in excellent order. The appa-
