N.B.--In every case, even in the trials V. and X., in which the
temperature in the disinfecting chamber rose above 320 deg. Fah., the
clothes, owing to the complete saturation of the hot air with live
steam, remained absolutely unimpaired.
The column "water evaporated" shows the quantity of live steam passing
through the disinfecting chamber averages 13 cubic feet per minute
with gas or spirits, and 22 cubic feet with charcoal or coke in the
portable and 33 cubic feet in the stationary apparatus. Trials VI.,
VII., and VIII. took place in open air.
According to trial XII., from 28 to 30 complete suits of clothes can
be disinfected at an expenditure of about 75 cbs. of coke per diem.
