The latest report of Admiral Mouchez states that thirteen observa- tories have decided to take part in the great work of making complete photographic chart of the stars. These should finish the undertaking in four or five years.
 The geological effects of ice seem to have been greatly exaggerated. From personal study of living glaciers in Norway and similar experience by others, Prof. J. W. Spencer declares that the potency of land glaciers to act as great eroding agents, capable of "planing down half a continent" or ploughing out great valleys or lake basins, or even of greatly modifying them, is most strongly negatived.
 It has long been known that an at- tack of erysipelas exerts a remarka- ble influence upon other diseases, and the attempt has been made to cure more serious maladies by deliberately inoculating the patient with the virus of erysipelas. In recent case in Nor way, the growth of 8 cancer was greatly retarded by this means, and life was probably prolonged few weeks or even months, though no cure was effected.
 Earthquake sounds, says Prof. Milne of Tokio, frequently precede the shock, are often heard during it's progress, and sometimes after the earthquake proper has ceased. Their character is vary varied, from barely audible rumbling to loud rattling like cart on 8 stony street or vol ley of musketry. They are probably heard better where the earth's struc- ture is hard and solid than where it is loose and soft.
 THE WORLDS SUMMIT. - Thibet, most of which is just becoming known to Europeans, is divided by Gen. s. T. Walker, of the Royal Geographical Society, into southern zone, 10000 to 12,000 feet above the sea, contain ing all the towns and villages of the settled population; middle zone, 12,000 to II, 800 feet high, comprising the pasture lands of the nomad Bod- pas, or pure Thibetans and a north ern zone, 14,000 to 17,5O0 feet above the sea, partly occupied at certain seasons by Turkic and Molgolian nomads, but mostly abandoned to wild animals. The country is about l4,o00 miles long by 500 miles wide.
 A PAIR OF GEOLOGICAL PUzzLEs.- The Grecian island of Cephalonia, in the Mediterranean, contains two rather remarkable natural phenomena. The first is a rock which oscillates several inches to and fro with the reg ularity of pendulum, pressing firmly against fixed rock one moment and directly afterward opening a space into which the clenched hand may be thrust. The motion is due to some unknown cause, having been found to be quite independent of the sea's &C., tion. In the other phenomenona about half million gallons of water daily flows upon the land by four inlets and is sucked into the earth. The water has been collected in a short canal to drive two mills, but disappears among the rocks, with no visible outlet, after being thus used.
 UMBRoAANIA. - A true art is claimed as development of the fla miliar diversion of making rude fig- ures by the shadow of the hands on the wall. Trewey, a French artist, has added great variety to these shadow pictures, and his fast -increas- ing list already numbers more than 300 new forms. By patient exercise, he has given his hands great supple ness, enabling him not only to repre- sent most diverse figures upon a screen, but to give them motion and life. The swan smoothing its plum
