Cor -on Waste Transformed Into Nitrate
 of Ce4iulose-A New i>JnaIno.
 An interesting discovery has been made by two young chemists of Lon don which will doubtless have very important bearing On the manufacture of cotton. rays a Lc1dol ccrrcspon- dent of the New York Times. Cotton waste is transformed by a new process into nitrate of cellulose, and cotton fabrics can be covered with a solu- tion of it which will add materially to the weight, strength and value of the material. Thin, lightweight fabrics can be filled up with this preparation. which costs little more than sizing and fullcr's earth. The cellulose thus pre- pared is also applicable to many differ ent purposes. The cost is very little more than the raw material, being cheap and the process of manufacture inexpensive.
 Another invention of moment is one which enables waste paper to be con- verted into kegs, barrels and vessels of every description. In making kegs and barrels ingenious machinery is em- ployed, which enables the manufac- turer to turn them out with solid heads if desired. There will be large de- mand for the product in the shape of kegs and barrels for powder, as no dampness can be contracted, since they are water and damp proof.
 The latest improvement in dynamos is one which gives continuous cur rent without brushes and accumula- tors. Scientists were incredulous and pronounced this impossible, but the proof of the pudding is in the eating, and the new dynamo gives a strong and continuous current notwithstand- ing it was declared an impossibility. At least one of the first electricians of England, who was an unbeliever, now certifes that the new dynamo is a suc- cess.
 Most important improvements have been made by an Austrian long domi- ciled in England in methods and appa- ratus for distillation. A new ferment has been discovered, and improve ments have been made in distilling ap- paratus and in mashing machinery and appliances which promise to complete ly reyolutionize the manufacture of spirits. The bye products which are saved and utilized leave the spirits al- most free of cost. The still is most important invention, since it separates the fusel oil and other products from the spirits in the process of distilla- tion, giving in three separate receivers the three distinct products, and, if re- quired, by simple change in the ap- paratus, instead of getting high wines, pure neutral spirits can be obtained, thus obviating separate rectifcation to produce refined alcohol. The ferment is made fresh for each mash and there results a luxuriant crop of yeast, which is treated and sold to bakers and for domestic purposes. This alone is source of large revenue to the dis tillers, as the yeast is of very superi- or quality and the demand for it is practically unlimited. The yield of spirits is more than one-fourth more than by old processes. Green malt in- stead of dried malt is used, which is source of considerable economy. The very best Irish and Scotch whisky is produced and fifty per cent raw maize substituted for the matted oats hereto fore used, which in itself effects very large saving.
