300 = On the Process of Bleaching with 
indebted to the justly celebrated Scheele ; and I am 
happy to pay this tribute to chemistry after the 
mortifying truths, which I have stated above. 
M. Berthollet lost no time in applying the pro- 
perties of this curious and highly interesting sub- 
stance to the most important practical uses.. His 
experiments on bleaching with the oxygenated mu- 
riatic acid proved cqmpletely successful, and he 
did not delay to communicate his valuable la- 
bours to the public. The new method of bleach- 
ing was quickly and successfully introduced in- 
to the manufactures of Manchester, Glasgow, 
Rouen, Valenciennes, and Courtray; and it has since 
been generally adopted in Great Britain, Ireland, 
France, and Germany. The advantages which re- 
sult from this method, which accelerates the process 
of whiteying cottons, linens, paper, &c. to a really 
surprising degree, in every season of the year, can 
be justly appreciated by commercial people only, 
_ Who experience its beneficial effects in many ways, 
‘but particularly in the quick circulation of their 
capitals, 
Great difficulties, for a time, impeded its pro- 
gress, arising chiefly from prejudice and the ignorance 
of bleachers in chemical processes, These obsta- 
cles were, however, soon removed, by Mr. Watt at 
Glasgow, and by Mr. Henry and Mr. Cooper at 
' Manchester, Another difficulty presented itself,which 
had nearly proved fatal to the success of the opera-
