In 1858 we find a publication of his “On a New Method 
of preparing Hydrochloric Acid.” 
In 1859 “On the Analyses of Wheaten Flours.” — “Influence 
of Science on the Arts of Calico Printing.” — “On Starches: 
the purposes to which they are applied, and improvements 
in their Manufacture.” 
During this year, his attention was called by the late Dr. 
Kansome to hospital gangrene, and in seeking its cause he 
was led to investigate the compounds produced during 
putrefaction. 
Two papers, descriptive of his results, appeared in I860, 
the first “ On Products of Putrefaction.” The second 
“On New Volatile Alkaloids given off during Putrefaction.” 
He continued, during the following two or three years, 
with these researches, and had collected about an ounce of 
a precipitate, produced by combining the gaseous products 
of putrefaction with platinum, by passing the gases emitted 
by the putrefying meat through bichloride of platinum, by 
m.eans of aspirators, during many months. This accumula- 
tion of precipitate was unfortunately destroyed before its 
examination could be completed, through the carelessness 
of one of his assistants, which caused him much regret ever 
afterwards. 
In 1861 he wrote “On Improvements in the Manufacture 
of Coloring Matters,” and “On the Chemical Composition of 
Steel.” A report followed “On the Action of Water supplied 
by the Manchester Corporation on Lead of different kinds,” 
in connection with the Manchester Sanitary Association. 
In 1862 he gave a seiies of lectures to the Society of Arts, 
“ On the Improvements and Progress in Dyeing and Calico 
Printing since 1851 ;” in 1864 “ On Chemistry as applied to 
the Arts;” in 1866 “On Discoveries in Agricultural 
Chemistry,” and “On Discoveries in the Chemistry of Rocks 
and Minerals.” 
These were the beginning of the Cantor lectures, which 
are now continued every year by different lecturers.
