864 does not always correspond with that of the locks. Generally, of ten thousand young men examined for military service, twenty were rejected for premature baldness, and fifty-two for diseases of the scalp. A few cases of red hair are found, and in one commune this color is predominant. The origin of this colored hair is a subject of discussion.

English National Fish Culture Association reports that its last year's growth of newly hatched salmon was six and a half inches, and of white-fish five inches.

meteorological reporter to the Government of India, is testing from year to year a theory of a connection between the Himalayan snow-fall and the monsoon, to the effect that the later and heavier the snow-fall in winter and spring, the later and feebler would be the following monsoon. The forecasts according to his theory were fairly accurate last year. This year they appear favorable to a prompt monsoon and abundance of rain.

naturalist remarks upon the frequency with which names derived from natural history arc adopted by the nobility of his country. Lion, eagle, tiger, wolf, and bear, and even mythical animals like the griffin and the dragon, have furnished several families with parts of their names. Most of the domestic animals are also represented, and plants, such as the lily, rose, laurel, cedar, oak, and lime, are still more fully represented. Numerous stars form the prefix of names, but in no case the sun or moon. The word stjerna, star, is used both at the beginning and at the end of names; but the stjerna in Oxenstjerna does not represent this word, but the German Slim, forehead.

conceives that the recent seismic catastrophe in New Zealand lends probability to his theory that that island is one of the remnants of a formerly existing Australian continent that has been submerged. Evidence was wanted of the liability, present or past, of the regions to shocks severe enough to suggest that former stronger shocks might have produced such phenomena of submergence as he predicates. The late shock was one of the kind.

and Mathias have reported to the French Academy of Sciences concerning their researches on the density of the liquefied gases—in the cases of protoxide of nitrogen, ethylene, and carbonic acid, that at the critical point the density of the liquid gas is equal to that of its vapor.

number of births in France per ten thousand inhabitants has diminished more than one third in a century. It was 380 in 1771-'80, 289 in 1831-'40, and only 241 in 1871-'80.

has given an interesting account of the egg-laying and hatching habits of the emu. The hen-bird lays her brood of twenty eggs or more, at intervals of two days, during about six weeks in October and November. Before the process is completed, the cock-bird begins to sit. The eggs laid subsequently are deposited by the hen by the side of her mate, who puts out his foot and draws them under him. As soon as the eggs begin to hatch it is necessary to isolate the hen, because she fights furiously with her mate and seems disposed to kill the chicks if she could get at them. The whole of the tending of the young is performed by the male bird.

first case of the admission of a woman to the French Academy of Sciences occurred on the 28th of June, when Sophie Kowlewska, Professor of Mathematics at the University of Stockholm, and daughter of the eminent paleontologist, was received as a member.

son of the Irish geologist, who had connected himself with an African trading company, was killed by a poisoned arrow in a fight with the native tribes at Anyappa, May 23d. His training as a chemist and geologist at scientific schools in Dublin and London had thoroughly qualified him for scientific research, and there is no doubt that had he lived he would have added much of value to our knowledge of Africa. death is announced of Mr. George Busk, F. R. S., a well-known English surgeon and naturalist, in the seventy-eighth year of his age.
