Non-Sparking Tools.--( Chemical Industries, Vol. 35, P. 45.) A new line of non-sparking tools has recently appeared on the market. Such tools should find frequent application in lacquering plants, by producers and processors of cellulose nitrate, oil companies and all other industries confronted with explosion and fire hazards in their production and maintenance work. These new tools are made of wrought beryllium copper; are non-magnetic and non-sparking and by actual test are almost as durable as steel tools of similar design and size. C. Prussic Acid Antidote.--(U. S. D. A. Clip Sheet, No. 842.) Three veterinary scientists of the Bureau of Animal Industry, A. B. CLAWSON, H. BUNYEA, and J. F. COUCH, have been testing various chemicals as remedies for prussic-acid poisoning. They found that methylene blue, sodium tetrathionate, sodium nitrite, sodium thiosulphate were effective and the two latter in combination being especially so. Hydrocyanic acid does not occur in dangerous quantities in healthy growing plants but does develop in many valuable forage plants when normal growth has been retarded or stopped by drought, frost, bruising, trampling, wilting, mowing or other cause. The antidotes listed, if administered in time, will save the lives of animals poisoned by eating such plants containing appreciable quantities of hydrocyanic or prussic acid. In the experiments, the first of their kind conducted under field conditions, the animals were drenched with doses of potassium cyanide in water ranging from a lethal dose to 2a~ times the lethal dose. The remedies were administered at various times after the cyanide was given. C.
