=The "Rabies" Bacillus.=--Ever since the discovery of Pasteur that an attenuated virus made from the medulla or spinal cord of a dog affected by rabies was, when administered in graduated doses, a specific against the disease, bacteriologists have been eagerly seeking to isolate the rabies bacillus. A number of observers, among them Toll, Rivolta, and San Felice, have succeeded in staining a bacillus which they claimed to be that of rabies. Memno, of Rome, confirmed the observations of the preceding, and proved the virulent character of the micro-organism, which he described as a blastomycete. He has quite recently succeeded in cultivating the bacillus in artificial media and producing typical rabies in dogs, rodents, and birds by inoculations. He found that the bacillus grew better in fluid than in solid media, the best being bouillon with glucose slightly acidulated with tartaric acid. The growth did not become manifest under a week, and was easily arrested by "air infection." It would thus seem that we have at last certainly established the bacterial origin of rabies. =The St. Kildans.=--St. Kilda, the farthest out to sea of all the British Isles, is a rounded mountain with "stack rocks" and islets round it, rises twelve hundred and twenty feet in height, and contains a settlement of about seventy-five men, women, and children--almost the only representatives left on the British Islands of man in the hunting age. On one of the subsidiary islands, Boreray, is gathered the main body of the sea birds for which the island is famous; and on a third, Soa, are the diminutive descendants of Viking sheep, left by old sea rovers. Mr. R. Kearton, who has recently visited the islands for recreation among the sea birds, represents that in the little community of its people the ordinary and extraordinary operations of life seem inverted. Sport is a serious work; sheep herding and shearing are an exciting sport. A St. Kildan qualifies for marriage by proving his courage and skill as a fowler, by standing on a dizzy precipice called Lover's Stone, and goes out bird snaring with a serious face. When he wants a sheep for the butcher, he asks his friends to a sheep hunt in the island of Soa, in which dogs and men pursue the animals from rock to rock. An offer made by a factor to supply the people with nets, so that they might catch the sheep with more humanity and less waste of life, was rejected by them. They preferred the old methods, which supplied plenty of danger and excitement. While the sheep are hunted, the cows are thoroughly spoiled. Every day the women are seen hard at work picking dock leaves and storing them in baskets for the cows at milking time, for they will not be milked unless they are fed. The sheep on Soa Island are plucked instead of being sheared, at the time when the wool would naturally be shed, and what wool will not come off in this way is cut off with a pocket knife.
