An accident of the ordinary sort occurred last night to the new Magnetic train, which was at the moment passing under the Channel, about 10 miles from Dover. From messages sent by the portable electric machine along the wires the moment before the catastrophe took place, it would appear that the engineers have been again at fault in the construction of the roof of the tunnel, and that the sea was rushing in with such violence that little hopes were entertained of bringing the train to the next watertight compartment. The result justified these fears, for the whole compartment of the tunnel in which the train was stopped is to-day entirely full of water, and it must be assumed that the unfortunate passengers—numbering, it is supposed, about 800—have been drowned like so many rats in a trap. The accident is unfortunate for the proprietors of Submarine Tunnel Stock, and also for several Insurance Companies, as extensive repairs will be required; but Science teaches us to regard these occurrences with composure, as serving to check the increase of a superabundant population. * * * * * The Simian Educational Institute (on Frobel’s system), for members of the Ape family, continues to attract the strongest interest. In testing the educability of the Simian tribe we are solving one of the most important problems of Science, and hitherto everything seems to promise the triumphant success of the experiment. There are now among the pupils at the Institute three Chimpanzees, whose grandfathers and grandmothers have all been well-educated monkeys; so that the set of the brain of these young people is already marked towards progress and civilization. It is needless to observe that all the students are required to wash and dress themselves every morning in the becoming male and female habiliments provided by the taste of the Governors of the Institute. Great pains are also taken with their manners at meal times, and, to avoid temptation, nuts are not admitted at dessert. One of the young gentlemen (Joseph Macacus Silenus, Esq., generally known by his intimates as “Joe”) is said to exhibit extraordinary talents, and to be able to answer any question in elementary science by means of an alphabet and a system of knocks, which (in view of the yet unconquerable speechlessness of monkeys) has been accepted as the best substitute for language, having been formerly invented by an ingenious race of impostors named Mediums, who flourished in the obscurity of the Victorian age. The plan adopted in France, in deference to the advice of the great French naturalist, M. Houzeau, to employ the anthropoid apes as domestic servants, has proved, we are informed, altogether successful in several families. Madame Le Singe, a fine specimen of the Gorilla tribe, has acted for some months as
