The paper-bottles made in Paris are cemented with a composition of alum, lime and blood-albumen. Neither water nor alcohol has any effect on these bottles, and of course, they are not easily broken.
 An important discovery in aeronautics is reported from Germany. By the aid of compressed carbonic acid the gas in bal looms is condensed or expanded at pleasure causing the balloon to ascend or descend a, the aeronaut's will
 The importance of acquiring a better knowledge of earthquakes has become SO well recognized in Japan that the authori. ties of Tokio University have instructed one of their officers to devote himself wholly to earthquake phenomena.
 A Scottish physician declares that of all the strange journeyings of needles in the flesh which have come under his observation, the strangest occurred in lady patient, who a year ago broke a needle in the first joint of her left thumb and a few days ago removed it from her right fore6nger.
 After many years of experimenting, German chemist claims to have succeeded at last in coating instantaneously all the ordi- nary metals and their alloys with thin film of brass, which can be varied in color. He uses only single b battery-cell, and obtains at will solid deposits of various hues and bril- liancy.
 A new process of separating mixed cotton and wool rags consists in subjecting them to the action of jet of superheated steam. The wool melts under a pressure of five atmospheres, and sinks to the bottom of the recs ptacle while cotton and other vege- table fibers stand, thus remaining suitable for the paper-manufacturer. The liquid mud containing the wool is then dried, and the residue, known as azotine, is valuable for its nitrogen.
 Among the recently proposed applica- tions'of luminous paint is the making of lu- minous tape for military use in marking ont projected earthworks at night. Such tape would expose no ray of light to the enemy. The paint has also been placed on glass and used for inspecting the interior of boilers,
 
 buckets to make them visible in the dark, and has even been placed on the back of glass with which an English railway carriage has been lined.
 Clouds of Condensed Gas.-In a note to the French Academy of sciences, Mons. A. Badoureau has offered new explanation of the light feecy clouds which appear in the upper regions of our atmosphere. He assumes that the temperature of these re- gions falls to the intense cold of space, which makes it appear probable to him that the carbonic acid, nitrogen and oxygen are here successively condensed into clouds analogous to those formed lower down by vapor. To such clouds may be attributed the phenomenal halos lately observed about the sun.
 Ancient Colors.-The natives os America were acqu ainted with the use of col ITS at a very remote period. Their first coloring materials were undoubtedly Sup piled by the ochres, root-blaek and lime while experiment gradually taught them to extract vegetable colors from leaves, fruits, roots, stems and seeds. An animal coloring matter. like the Tyrian purple, was yielded by sea-mollusks. The Peruvians and the Mexicans were able to dye their cloths, and Peruvian mummy-wrappings which have been found after having been buried for centuries still retain their primitive coler.
 Europe's Northern Point-Mr. w. Mattieu Williams stateslthat he drew atten- ton in 1877 to the fact that the North Cape is not the northernmost extremity of Europe, as it is generally believed to be. A low tongue of rock, called skjierodden or Knivsjae- lodden, about a mile to westward of North Cape, projects farther north than the cape itself. This insignificant appearing rock hardly seems to deserve she name of cape" in the presence of the magnificent capes about it. North Cape presenting a perpen- dicular face e74 feet high, and others having height of over 1000 feet. A It should not be forgotten" MT. Williams adds, "thas neither North Cape nor this little ambitious out poke is the northernmost point of the European continent. This distinction be- Knivskjaelodden being on Magero, an out lying island"
 Defective Ears.-The results of certain inquiries which have been made concerning the statistics of ear disease have been made known by Dr. Buskner, German physician, and may be stated briefly as follows: Every third person in middle life does not hear so well with one ear as with the other. In an examination of sos school children 1t was found that 8 per cent. presented symptoms of actual disease of the ears, while sa per cent. showed a diminution of hearing power. The liability to disease of the ear increases from birth to the fortieth year, and then de- eresses to old age. ssen are more subject, 10 ear affections than women, in the proportion of three to two. The external ear is af- fected in as per cent of the total eases, the middle ear in 6 per cent, and the inner ear in per cent. The left ear Is more ire quently affected than the right in the propor- ton of five 10 four Acute affections of the
