Leaving the centre-room of the three in the College roof, let us just glance at the other two apartments. Upon entering one we see the walls lined with boxes, something like those in a milliner’s shop, but, instead of holding laces and ribands, we find them labelled “Wolf,” “Racoon,” “Penguin,” “Lion,” “Albatross,” and so on with names of birds, and beasts, and fishes. On lifting a lid, we find the boxes filled with the bones of the different creatures named; not a complete skeleton of any one, perhaps, but portions of half-a-dozen. In this room, the two students attached to the College carry on dissections, under the directions of the superior authorities. What they do is entered in a book kept posted up, and this affords another source for reference as to anatomical facts. When they have laboured here for three years, they have the option of a commission as Assistant Surgeon in the Army, Navy, or East India Company’s service, as a reward for their College work. If the atmosphere of the two apartments we have investigated was bad, that of the third room was infinitely worse, though windows and ventilators are constantly open. In this place large preparations are kept, and all the specimens are here put into the bottles required for exhibition in the Museum. This third room, like the first, has a curiously characteristic look. It would make a fine original for a picture of an alchemist’s study. On one side is a large structure of brickwork with pipes and taps, conveying the idea of a furnace and still, or of an oven. Alongside it is a bath and a table, and the purpose of the whole is for _injecting_ large animals. This is a very difficult operation, the object being to drive a kind of hot liquid sealing-wax into every artery of the body, even the most minute. All things brought here, and capable of it, are injected somewhat after this fashion before they pass under the scalpel. Besides this oven-looking structure there are pans, and tubs, and casks; one containing a small dromedary, another being “a cask of camel.” A painter’s easel stands there ready for use, and on the floor are some bones of a megatherium; the tables are covered with bottles and jars, and the walls are similarly decorated. Strings of bladders hang about, and under foot we see thin sheets of lead coated with tin-foil; these latter being used for tying down the preparation bottles so that they may for years remain air-tight; a tedious and somewhat difficult operation. In this place every year they use scores, sometimes hundreds of gallons of alcohol; one fact which helps to show that museums on a large scale are expensive establishments.
