 The use of oil on water to proven or remove fogs is suggested.
 It is stated that two-thirds of th' wood used in paper making is waste though experiments indicate that thi can be profitably converted into fer tilizers.
 A new utilization of waste pro. duct is the manufacture of paper iron the cedar chips of pencil-makers. Th' paper is said to keep moths from car. pets, wool, furs, etc.
 Means for the accurate comparison of electrical standards and apparatui are to be supplied at Johns Hopkins university, no provision for such meas urements having been made elsewhere in the United States.
 A curious monstrosity has been ac. quired by the Paris Museum of Natu. ral history. It is an apparently healthy sow, having one head, one thorax and two forelegs, with two trunks, two tails, and four hind legs.
 During the total eclipse of January 28 a satellite of the moon was sought for by Prof. Pickering, of Harvard university. None was seen, and the conclusion was reached that if one ex. ists it's diameter must be less than two thousand metres.
 Onion juice is said to be remarka- bly, adhesive paste for attaching pa. per to zinc. The metal should be cleaned with strong, hot solution oi washing soda, and then rubbed dry Cheap clock dials are made by attach ing payer to zinc by this means.
 Each soldier of the Netherlands it to be supplied, in case of war, with 6 cartridge three inches long by two wide, containing antiseptic dressings These will consist of bandage about three yards long and two pieces ot gauge, all rendered antiseptic by a sublimate solution.
 On the right bank of the Volga re- mains of an ancient town, traceable over a length of two miles and a breadth of three- quarters of a mile, have been discovered. Arabian, Per- sian and Tartar coins have been found, with many other objects of an ad- vanced civilization.
 ANOTHER GAs.-The discovery of a new gas has been reported by two English chemists, Prof Thorpe and MT J. W. Rodger. It is sulpho- fuoride of phosphorus, best prepared by heating pentasulphide of phospho- rus with lead fuoride in a leaden tube, and has been named thiopho- sphoryl fiuoride. It infames sponta- neously on contact with air.
 ANCIENT VEGETATION. - Remains from coal beds prove that the ferns, of which several thousand species are known, constituted a very important part of the earth's earlier vegetation. They are still abundant, especially in moist tropical regions. In the Antilles they comprise about one- tenth of the vegetation; in Oceanica, one- fourth or one-fifth; in St. Helena one- third in Juan Fernandez, one-half; and in England, one- thirty fifth.
 UNBREAKABLE GLAss.-An unbreak- able substitute for glass is made by Mons. L. c. A. Marguerite, of Paris, by immersing wire gauge in a heated state in a thin paste formed of soluble glass, gelatine and glycerine, or glu- cose, in proportions varying accord ing to the use for which the material was designed. When nearly dry the sheets are dipped in a concentrated so- lution of chrome alum or bichromate of potash. Any desired coloring mat ter may be incorporated with the gel atine, and copal or other protective varnish may be applied to the "vit- reo-metallic" panes.
 AINo AGRIcULTLRE.-The British consul at Hokodade states that the Ainos-who are remarkable tribe of small, hairy people, originally living by hunting and fishing-have been in great straits since the occupation of their fishing grounds by the Japanese in 1869. Since 1882 efforts have been made to relieve their distress and to teach them farming, and in 1886 about sos acres were cultivated by them. In their chief home in the island of Yesso, the Ainos are estimated to number 14,000 individuals, with $500 houses. They are supposed to be gradually disappearing.
 ANEW FLoRA.-The luxuriant veg- citation of Krakatoa was totally de- stroyed by the eruption in 1883, not a living germ being left. Three years later the island was visited by Dr. M. Ireub, who now reports having found six species of microscopic algae, which
