If one of the professors of his medical school chances to be addicted to making anti-Martin experiments on animals, or the study of comparative anatomy, the pursuits offer an endless fund of amusement to the jocose student. He administers poison to the toxicological guinea-pigs; hunts the rabbit kept for galvanism about the school; lets loose in the theatre, by accident, the sparrows preserved to show the rapidly fatal action of _choke-damp_ upon life; turns the bladders, which have been provided to tie over bottles, into footballs; and makes daily contributions to the plate of pebbles taken from the stomach of the ostrich, and preserved in the museum to show the mode in which these birds assist digestion, until he quadruples the quantity, and has the quiet satisfaction of seeing exhibited at lecture, as the identical objects, the heap of small stones which he has collected from time to time in the garden of the school, or from any excavation for pipes or paving which he may have passed in his route from his lodgings. The second or middle course of the three winter sessions which the medical student is compelled to go through, is the one in which he most enjoys himself, and indulges in those little outbreaks of eccentric mirth which eminently qualify him for his future professional career. During the first course he studies from novelty--during the last from compulsion; but the middle one passes in unlimited sprees and perpetual half-and-half. The only grand project he now undertakes is "going up for his Latin," provided he had not courage to do so upon first coming to London. For some weeks before this period he is never seen without an interlined edition of Celsus and Gregory; not that he debars himself from joviality during the time of his preparation, but he judiciously combines study with amusement--never stirring without his translation in his pocket, and even, if he goes to the theatre, beguiling the time between the pieces by learning the literal order of a new paragraph. Every school possesses circulating copies of these works: they have been originally purchased in some wild moment of industrious extravagance by a new man; and when he passed, he sold them for five shillings to another, who, in turn, disposed of them to a third, until they had run nearly all through the school. The student grinds away at these until he knows them almost by heart, albeit his translation is not the most elegant. He reads--"_Sanus homo_, a sound man; _qui_, who; _et_, also; _bene valet_, well is in health; _et_, and; _suae spontis_, of his own choice; _est_, is," &c. This, however, is quite sufficient; and, accordingly, one afternoon, in a rash moment, he makes up his mind to "go up." Arrived at Apothecaries' Hall--a building which he regards with a feeling of awe far beyond the Bow-street Police Office--he takes his place amongst the anxious throng, and is at last called into a room, where two examiners politely request that he will favour them by
