REMARKS ON THE PREPARATION OF SOME OF THE SALTS OF 
MANGANESE. 
By W. W. D. Liyermore. 
Manganese as a remedial agent has repeatedly attracted the at- 
tention of physicians, but for reasons not clearly stated has as often 
fallen into disrepute. 
Lately, however, it has been again revived, and brought more 
prominently into notice by M. Hannon.* This gentleman recom- 
mends several forms in which it may be prescribed with advantage 
particularly the sulphate, carbonate, tartrate, phosphate, and io- 
dide; and as this metal enters into the human organism, we have 
reason to suppose that, like iron, some one or other of its combi- 
nations might frequently be used with success in the treatment of 
disease. 
The manganese preparations possess advantages over those of 
iron, in being free from astringency, and compatible with as- 
tringent vegetable infusions and extracts, and consequently, afford- 
ing the practitioner facilities for exhibiting it in ccnjunction with 
other substances, and by these means enlarging its sphere of use- 
fulness. 
The salts of manganese though numerous, may all be obtained 
either directly or indirectly from the sulphate, and therefore it 
becomes a desirable object to discover the best and most expedi- 
tious process by which this salt may be obtained.
