select because it is the subject to which several pages of the 
present Number are devoted. 
u Iodinum, Iodine. 
“ Iodine and its compounds have not yet come into general 
use amongst veterinarians ; I have little doubt, however, that 
they will. Iodine is obtained from the mother water, after the 
procuration of carbonate of soda from sea-weeds. The avail- 
able compound which remains is an hydriodate of soda : sul- 
phuric acid being poured on this, it seizes on the soda, setting 
the hydriodic acid free.” 
He now relates the chemical process by which this is accom- 
plished. 
“ Iodine is solid at the ordinary temperature of the air, and 
occurs in dark-coloured scales, which have a metallic lustre : 
when sublimed, it forms rich violet-coloured vapours ; hence the 
name given to this substance. It has a pungent odour, an acrid 
taste, and it tinges the skin of a brownish-yellow colour. Weight 
of its atom 126. Its action is that of a stimulant to glandular 
structures, and the forms in which it is employed externally ares 
those of a liniment and ointment. 
“Linimentum Iodinii Compositum, Compound Liniment 
of Iodine. 
“Take of Iodine 1 part 
Soap Liniment 8 parts. — Dissolve. 
“Unguentum Iodinii, Ointment of Iodine. 
“ Take of Iodine 1 part 
Lard 8 parts. — Mix. 
Some substitute for lard the milder ointment of mercury, by 
which a far more active compound is formed. Others add half 
a part of cantharides in powder, or tartar emetic. 
Administered internally, the form of tincture is advocated. 
“ Tinctura Iodinii, Tincture of Iodine. 
“Take of Iodine 1 part 
Rectified spirit ... 8 parts. — Dissolve. 
The dose of this is from 3 j to 3 ij, given twice or thrice a-day. 
In the practice of Mr. Packwood, of Coventry, farcy has yielded 
to it.
