It is to the Museum that the students repair two or three times a week, and gain a practical knowledge of the ailments which are associated with animals. The glass cases contain horses' mouths, showing the various stages of the teeth. Innumerable are the bottles holding preserved portions of each and every animal. In one of the cases is a very interesting specimen of the students' work. It illustrates the anatomy of a dog's leg. The bone is taken in hand by the student, and by an ingenious arrangement of red sealing wax the blood-vessels are faithfully and realistically introduced. Every case contains a curiosity--one is full of the feet of horses, and its next-door neighbour protects a wonderful array of horseshoes. The ideal horse-shoe is one which requires no nails. The nearest approach to this is a shoe which clamps the hoof, is screwed up tightly, and the whole thing kept in place by an iron band. The great amount of pressure which is required to keep the shoe from shifting, and the possible injury it may cause the wearer, has prevented its universal use. Here is an old-fashioned drenching bit--the old idea of administering medicine to horses. The bit is hollow and a funnel is attached to it, to be inserted in the animal's mouth and the mixture poured in. To-day, however, a tin drenching can of a somewhat pyramidical shape is simply used. [Illustration: "POLLY."] At the door one may brush against what appears to be a mop of extra size. It is--to use a homely expression--a calf's leg with "a housemaid's knee." This curious growth is five feet in circumference and a foot and a half in depth. But perhaps the most remarkable corner is that devoted to the storing of massive stones and cement, hardened together, which have been taken from the bodies of various animals. These are of all shapes and sizes. Two of them taken from a mare, weigh fifty-four pounds, and many of them would turn the scale at thirty-five to forty pounds. The formation of such stones is curious. Above is a drawing--in miniature--of a huge stone formed inside a cow. The cow--by no means a careful one--enjoyed the green grass of the meadow in blissful ignorance that even tin-tacks and nails get lodged on the sward occasionally. The cow, in her innocence, swallowed the nail--there it is, imbedded in the centre. Lime and earth deposited and hardened round it, with the result that an immense stone was formed of nearly forty pounds in weight. [Illustration: "JOE."]
