Ouo's process published was imperfect. nasmuch as the acid used was not described; and neither time nor temperature stated. The tuning Ntric Nitrous Acid was used by him, and only thirty seconds time allowed for action 10 be completed. This would not often be the result and takes place only with the very volatile acid frat obtained by dislillation. Dr. waach,er modified this process by us'ng mixture of the strongest nitric and sulphurc acIds, two parts | of tho latter to one of the former by wslght
 In England the principle which tho manufacture is based also discovered, and equal weights of the two acids are prescribed Experiments which I made here, indicated that ihe mixture of the i've | acids gave certainty to the operation, and the Gun Cotton produced few hours before the accounts of success elsewhere had reached me.

Aher the lapse of thirty or forty minutes, press the soaked cotton be- tween glass plates, firmly; immerse them in abun- dance of cold water, and the ocks apart so as vy rapidly wash out the greater part of rhe acid The hocks must then bo washed in different waters till every trace of acid is removed md dried in free air below PIP deg. The same quantity of acid will answer for successive iocks, till half consumed. In my trials some cotton left six hours in the strongest acid and the product was excellent.
