scrofulous taint ; paralysis, leucorrhoea, syphilitic enlargements, &c. 
Mr. Rickwood relates four cases of bronchocele, which were relieved 
or cured by this medicine, and considers it to be an excellent tonic 
in other diseases ;* and Mr. Callaway, surgeon, of the Borough, has 
employed Iodine (we believe the tincture) in several cases of scro- 
phulous enlargements of the glands, both of the surface and of the 
mesentery, with decided good effects. 
Iodine has been exhibited both internally and applied externally ; 
for the former purpose, the tincture of Iodine, or a solution of hy- 
driodate of potass in distilled water, has been generally preferred. 
The following formulae are given by Magendie : — 
Tincture of Iodine. 
Take of Alcohol at 35°, 1 once, (7 dr. 62| gr. troy) 
lofJine 48 grains, (gr. 39. 36 troy) 
This tincture should not be prepared long before it is wanted for 
use, as it soon deposits crystals of Iodine, and consequently loses 
its powers ; the dose to adults is ten drops, two or three times a day, 
gradually increased to twenty or more. 
Solution of Hydriodate of Potass. 
Take of Hydriodate of Potass, 36 gr. 
Distilled Water 1 once. Mix. 
This solution has been given in doses of ten drops, gradually 
increased to twenty. 
Ointment of Hydriodate of Potass. 
Take of Hydriodate of Potass, 29| gr. 
Hog's Lard i| once. Mix. 
This ointment has been used with decided advantage in the way of 
friction, in treating bronchocele or enlarged scrofulous glands; 
the complete resolution of which has followed the steady applica- 
tion of this remedy. This ointment has been generally made use of 
in the quantity of from one to two drachms, gently rubbed over the 
surface of the tumour night and morning: it has also been used in 
conjunction with the internal exhibition of Iodine. We must observe 
with regard to the above preparations, that the precise doses must 
be regulated according to circumstances, which the intelligent prac- 
titioner will be at no loss to discriminate.
