The Tarahumare people, who live in the most inaccessible part of northern Mexico, were described by Dr. Krauss in the British Association as ignorant and primitive, and many still living in caves. What villages they have are at altitudes of about eight thousand feet above the sea level. They are a small and wiry people, with great powers of endurance. Their only food is pinoli, or maize, parched and ground. They have a peculiar drink, called teshuin, also produced from maize and manufactured with considerable ceremony, which tastes like a mixture of sour milk and turpentine. Their language is limited to about three hundred words. Their imperfect knowledge of numbers renders them unable to count beyond ten. Their religion seems to be a distorted and imperfect conception of Christian traditions, mixed with some of their own ideas and superstitions.

The directory of the School of Anthropology of Paris, which consists chiefly of the professors in the institution, has chosen Dr. Capitan, professor of pathological anthropology, to succeed M. Gabriel de Mortillet, deceased, as professor of prehistoric anthropology. Dr. Capitan's former chair is suppressed.

The highest cog-wheel railroad in Europe and probably in the world is the one from Zermatt, Switzerland, to the summit of the Görner Grat, upward of eleven thousand five hundred feet above the sea. It is between five and six miles long, and rises nearly fifty-two hundred feet, with a maximum grade of twenty per cent. There are two intermediate stations, at the Riffel Alp and the Riffelberg, and the ascent is made in ninety minutes. The height of this road will be surpassed by that of the one now being erected up the Jungfrau.

Extraordinary advantages are claimed by Mrs. Theodore R. MacClure, of the State Board of Health, for Michigan as a summer and health-resort State. The State has more than sixteen hundred miles of lake line, the greater part of which is or can be utilized for summer-resort purposes; there are in its limits 5,173 inland lakes varying in size and having a total area of 712,864 square acres of water. The many rivers running through the State furnish on their banks delightful places for camping and for recreation.

An action of bacteria on photographic plates was described by Prof. P. P. Frankland at the last meeting of the British Association. Ordinary bacterial cultures in gelatin and agar-agar are found to be capable of affecting the photographic film even at a distance of half an inch, while, when they are placed in contact with the film, definite pictures of the bacterial growths can be obtained. The action does not take place through glass, and therefore, as in the case of Dr. W. J. Russell's observations with some other substances, it is considered probably due to the evolution of volatile chemical materials which react with the sensitive film. Many varieties of bacteria exert the action, but to a different degree. Bacterial growths which are luminous in the dark are much more active than the non-luminous bacteria hitherto tried.

Telephonic communication, it is said, has been established between a number of farms in Australia by means of wire fences. A correspondent of the Australian Agriculturist from a station near Colmar represents that it is easy to converse with a station eight miles distant by means of instruments connected on the wire fences, and that the same kind of communication has been established over a distance of eight miles. Several stations are connected in this way.

R. S., author of books on marine zoölogy, February 2d; Major J. Hotchkiss, president in 1895 of the Geological Section of the American Association and author of papers on economic geology and engineering; Wilbur Wilson Thoburn, professor of biomechanics at Leland Stanford Junior University; Dr. Giuseppe Gibelli, professor of botany in the University of Turin; Dr. G. Wolffhüzel, professor of hygiene in the University of Göttingen; Dr. Dareste de Chavannes, author of researches in animal teratology, and formerly president of the French Society of Anthropology; Dr. Rupert Böck, professor of mechanics in the Technical Institute of Vienna; William Colenso, F. R. S., of New Zealand, naturalist and author of investigations of Maori antiquities and myths; Dr. Lench, assistant in the observatory at Zürich, Switzerland; Dr. Franz Lang, rector and teacher of natural history in the cantonal schools of Soleure, Switzerland, and one of the presidents of the Swiss Natural History Society, aged seventy-eight years; Dr. William Rutherford, professor of physiology in the University of Edinburgh, and author of several books in that science, February 21st, in his sixtieth year; and Sir Douglas Galton, president of the British Association in 1895 and an authority and author on sanitation, March 10th, in his seventy seventh year.
