 Mons. Eriehsen, of Copenhagen. h. produced from asbestos an enamel io. walls. pipes, etc, which resists the aet,o, of fire, water, frest and oxygen. n. coating material is prepared by powoe,. ing the asbestos and mixing it with so.s. ble saits-such as silicate of potash and mineral or other colors which pre,. erly combine with silicic acid.

 Al the laboratory of Mons. Amaga,. France, the heat of furnaces IS measure by stream of water flowing through spiral tube. The water, passing at a no.. crate rate, IS warmed only a few degree, even when the tube is made very h. The How IS kept al constant rate. ar the temperature of the furnace is eale.. lated very accurately from the increa.. 1t causes in the waters heat. as indicate: by an ordinary thermometer This wa,e. Pyrometer has proven very reliable II measuring temperatures of 900 degree. Fahrenheit and higher
 MT. 5. x. Rhoads has given evidens. which proves that undergraduates are c. recied 10 their prey from great distance. by their sense of smell, and not by sigh, alone. He partly uncovered a spot whe,e horse and COW had been buried some years before, and in a few hours bu.. zards were attracted to the place in grea: numbers. They must have been guide: by smell, and, as Mir. Rhoads could de. tect no odor when directly over the bur. ial-place, it is shown that their smelling power is marvellously delicate. Gossc re. iates an instance in which yultures circle. round house in Jamaica where some spoiled mea; was hidden.
 Several instances have been recorde3 ot probable injury to the brain as re- suit of too little activity in some part 0: the body, and case of rain-was,in. arising from the ampu,ation of a lint has recently been communicated to the Paris academy oi medicine by Mons Bourdon A soldier, who lost his e. arm some forty years ago, lately d.ea and a post-mortem examination shovei differences in the two sides of his bra. which indicated that one side had beer affected by the removal of the arm. To- ward the close of the mans life his le,: leg gradually became lame, in conse- quence, |, is supposed, of the injury dore 10 the brain.
 Dr. ]. ]. Wild, F. K. G. S.. sums up IS follows the results of recent investigation. into the causes of the color 0! the sea. and Of the apparent discolorativn of the sea-water Tn certain areas of the ocean he various tints of blue and green which constitute what may be called the proper color of sea-water are due to 4 greater or less proportion of salt held Tn solution, the color being an intense blue when the water IS very salt, and changing by degrees to green-blue, or blue-green and green color as the water become more fresh. On the other hand, the ab- normally colored red. yellow, brown and inky seas owe their appearance to the accumulation oflarge masses of sea-weeds from the gigantic algae, which fringe the shores of oceanic islands, to the micro scopic diatoms but almost as freouently the diseoloraiion is caused by myriads O. animal organisms collected in shoals a. the surface of the ocean,
 A letter from Mir. Edward Whympc. to Prof Norman Lockyer, the Enriish astronomer. gives some interesting par ticulars concerning an eruption of the South American volcano of Ce,opax.. which occurred in 1880. At the com mencement of the eruption, MT. Whyn- per was making his famous ascent oi Chlmoorazo. and was more than i6,ooo fee, above the sea-leavel, and about sixty-fiye miles from Cotopaxi A dense column of smoke was seen to rise suddenly from the volcano ,o height of abou, 10000 feet above the sea. when i, was borne westward some twenty miles by strong wind, and then gradually spread in al. directions In iew hours the clouc passed between the observers and the sun. and color effects surpassins in vivid intensity those of the most gorgeous sun sets were then witnessed, the sun itself ap bearing green. As the cloud passed overhead and surrounded the mountain the brilliant colors ceased to be seen, while an exceedingly fine dus, fel upon everything.
