Muriat of Potash, 223 
pounds of alkali to the gallon) which I found en- 
tirely relieved us from the disagreeable smell we 
frequently experienced before; and, at the same 
time, yielded a considerable quantity of the oxy- 
genated muriat. ‘Though the production of the 
oxygenated muriat in this way be somewhat pre- 
carious, depending upon the management of the 
person who conducts the process; (it being the 
bleacher’s interest to condense the whole of the gas 
in the liquor he wants for his business) yet I think, 
ifthe portion which commonly. escapes were thus 
disposed of a considerable quantity of this salt 
might be made by bleachers with little addition- 
al expence, except what is incurred by the pur- | 
chase of the alkali, and some more labour and at- 
tention. At some of my first trials, about two 
years ago, I found the gas which escaped from the 
materials of one distillation sufficient to saturate 
two gallons of the alkaline solution, from which I 
procured about six ounces, and sometimes more, of 
the salt, after being purified by several chrystalliza- 
tions. But, having made some alteration in the 
apparatus, I now find, that the same quantity of al- 
kali may remain for three or four distillations, be- 
fore sufficient gas be furnished to form the salt; 
except the person employed be remarkably inatten- 
tive to his duty. I consider this as a valuable’im- 
provement, the making of the salt being only a
