Not illustrated. 1898 Excerpt: ...hours. The impracticability of hot air disinfection is indicated by their statements that, in using hot air, the heat penetrates so slowly that with a temperature of 140 the interiors of quite small bundles of clothes, or of pillows are not disinfected in three or four hours; and that the action of hot air of 140 injures most objects more or less. The experiments of Klein and Parsons4 also show very conclusively the inefficiency of the hot air disinfectors which had been largely in use. These experiments and the practical experience of health officers have gradually taught that, as compared with steam, hot air is much less certain and rapid in its action. It is, therefore, now but little used except in special work, on a small scale. 1. Medical Standard, XX., 53. 1898. 2. Mittheil. aus dem Kals. Ges., I., 234. 1881. 3. Mittheil. aus dem Kals.

By heat as an auxiliary in disinfection, reference is made to temperatures below that of the thermal death points of the bacteria in question, and often far below. This increase in the activity of disinfecting solutions as their temperatures are increased is illustrated by Behring's1 observation that the bacillus of cholera and sporeless anthrax bacilli were destroyed with a I:100,000 solution of mercuric chlorid at 36 C. (95.8 F.), but at 3 C. (374 F.), these bacteria were not destroyed with a lesser strength than 1:25,000. Again with a 1.4 per cent. solution of washing soda, anthrax spores were killed in ten minutes at from 80 to 83; in fifteen minutes at 77; in twenty minutes at 75; and in from 30 to 60 minutes at 70. Remouchamps and Sugg2 found that pieces of linen soiled with cholera and typhoid dejectio...
