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.
