The accompanying engraving gives an excellent idea of the form of the instrument and the reagents Royal letters patent have been allowed him for the following novelties connected with its construction. It is waterproof, but not air-tight. This great desideratum, and apparently contradictory condition, is attained by the introduction of ventilating air-tubes passing behind the ankles to permanent outlets on either side of the boot. The act of walking causes a pumping action, thus a current of fresh air is drawn through the boot. By this means the feet are kept dry, and at the same time free from the perspiration from which so many persons suffer, and which is not only an annoyance and impediment to exercise, but a prolific This boot can be put on and cause of chills and colds. taken off with great rapidity, for lacing, unlacing, and tying are done away with, the "lacing" being very ingeniously effected by simply drawing the lace tight, passing it two or three times round the ankle, and inserting it through a patent "grip catch," which holds it effectually.

It would therefore be necessary for them to continue their habits of study, and he expressed a hope that when they arrived at his age they would be able to look back and thank God that they had done their duty. Sir T. Crawford concluded by moving a vote of thanks to Dr. Quain. ’ Sir J. Fayrer, in seconding the vote of thanks, also congratulated the students on their success, and expressed the hope that they were entering upon a long, brilliant, and successful career. He said that they had a great future before them in the greatest service in the world, for such he considered the British and Indian Medical Service, and he felt certain that they would do justice to it.
