Dissection and the making of a post-mortem examination, though often confounded in the public mind, differ materially. Dissection consists in minutely tracing out all the important structures of the limbs, body, and vital organs, and thus it takes several weeks’ hard work to get through a whole subject; while a post-mortem examination is the labour of an hour or two, and consists in examining and noting the pathological conditions of the internal organs, with a view merely to discovering the cause of death. An adult subject is worth about £5 when properly prepared for research. Each arm and leg, the half of the head, the chest, and the rest of the trunk, was charged to the student requiring it at St. Bernard’s, 12_s._ 6_d._, and he was expected to make good use of his opportunity. Every portion removed by his scalpel was carefully gathered up by a porter, and every night and morning placed in a coffin in the vaults below. When a coffin is filled with this minutely divided humanity, it is sent to a cemetery and buried as “our brethren and sisters departed.” The provisions of the Anatomy Act forbid the taking of any portion of the subjects out of the schools; nevertheless more than one ardent student whom we see in the room will finish his work on the hand or the foot at his own lodgings, to the horror and disgust of his landlady if she catches him at it. Some men never make good dissectors; they can cram up what they want for their examinations without the infinite pains required for a beautiful “preparation” such as is being made at this table on our right for the college museum. It is an arm, and every muscle stands out clean and clear, every artery is seen with its vermilion wax injection running its sharply defined course, and anastomosing with its neighbouring vessels. Here are the nerves like silver threads, becoming, like the blood supply, smaller as they reach the fingers, till they are lost in their terminations at the tips. It requires a man with a special genius, and the gift of an infinite capacity for taking pains, to do work like this, and many take a pride in doing it. Round this table on the left is a group of junior students, listening to the demonstrator, who is lecturing on the muscles of the chest, or thorax as it is called, and asking each of his auditors in turn some question to test his knowledge, and explain his difficulties if he have any.
