THE PASSING OF THE PAINTBRUSH.

Compressed air under suitable co.v trol is superseding- the brush as s means for distributing paint. The new practice is finding favour not only ; in studios, but in the most extensivt j work of protecting structures from j rust and atmospheric decay. The ; ease with which a fresh surface oi j paint can be distributed by a brush j drawn across it is well known to all ; who have striven to secure equality ir j their woik. With an air spray any thickness or density of paint can be ! obtained without the contact of the j distributor with the • urface undei ! treatment. Painting with compressed j air also proceeds from five to sever | times as rapidly painting will brushes. When duct.cl o:i th industrial scale three : qua re yards car be covered in one minute, and a sur face obtained which i superior to anything that can be created bv brushes. MANUFACT!'RED MARBLE. Much interest is being taken m a: invention by a citizen of Reichenbcr.tr Bohemia, of a process f r producing a substitute for all classes d marble including- the mo t highly-prized !:.• •an, Egyptian, and Salzburg marbli - Thp claim is made that the product n superior to genuine marble, bein’. stronger, more substantial, and 1< liable to crack or damage, and that iinstallation work the danger of injur; is much less than with real marble while it costs only one-third as much This artificial marble i- made parti; >v hand and partly by machine,' 'J cutting- and polishing* are done 1>; machinery, the process being already in operation in Vienna, Berlin, Mann heim, and Hamburg, and arrange rneuts have been made for selling th right to produce it in France and Russia, while the sale of patents to a Lon don company for the British Isles iabout to be consumated* LUMINOUS ANIMALS. It is well known that many animals possess the power of becoming luminous at will. Glow-worms are the most striking example of this curious phenomo non. Many fish that livo in the deep seas possess this same power of becoming luminous. Scientific men have vainly tried to explain the mechanism of this luminosity. MM. Ville and Donien, of Montpellier, explain this production of light by the oxidation of a substance secreted by luminous animals called lopbine. This organic azoted substance, under the influence of oxygon, ornEs a visible luminosity. Potash, in the presence of catalytic elements, such as the ferruginous matters of tlio blood, likewise provokes the oxidation of the lophLn#, and consequently forms light. Oxygenated water has also the same property. In the organisms it is unstable ozygen of the tissues catalysed by the ferruginous elements of the blood that produces the oxidation of the lophine and lenders animals luminous
