We learn from the London Lancet that besides the special ward of twelve beds at the Royal Southern Hospital of Liverpool, which was formally opened by Lord Lister on April 29th last, arrangements have been completed for a school for the study of tropical diseases at Liverpool. Lord Lister, on the occasion of the school's foundation, said: "The medical student in the ordinary hospital has rare opportunities of seeing these diseases, and for a man who is about to practice in the tropics it is essential that he have opportunities for studying them here before embarking on his tropical career. The possession of tropical colonies makes such institutions in the home country very necessary, not only for preparing the colonial doctors, but for the protection of the home population, which is sure to be brought into contact more or less with the infectious tropical diseases." An interesting paper by Mr. C. J. Coleman on The Electrical Protection of Safes and Vaults is described in the Electrical World and Engineer. He divided the methods into two systems, in one the alarm depending on the opening and the other on the closing of a circuit--the latter of the two being the one most in use. Among the curious devices mentioned are cementing narrow tin-foil strips on the inner surfaces of window glass, so that any breakage or fracture of the glass will open the circuit; the use of glass tubes filled with mercury and connected in circuit, or tubes filled with water or compressed air. In reply to questions as to the use of electricity in perforating safes it was stated that a five-ply chrome steel safe, seven inches and a half thick, was burned through by three hundred ampères in twenty-five minutes, and holes were burned through a solid block of vault steel twelve inches thick in twenty-six minutes with three hundred and fifty ampères, and in fifteen minutes with five hundred ampères.
