it the sulph. acid with the potash of the hydriodate, and 
“~~ with the hydrogen of the hydriodie acid, produces vitrio- 
_- ated tartar, water, sulphureous acid, and iodine. The 
__ jodine enters the receiver in a violet gas, along with a 
Little acid, and is there condensed. It is subjected to 
2 oe purification, by re-distillation with water containing some 
oe ariee : 
The preparations are : 1. Iodate of potash ; 2. Hydriodate of 
potash; 3. Hydriodate of soda; 4. Solution of hydriodate 
of ; 5. Tincture of iodine; 6. Ointment of hydrio- 
' date of potash; 7. In substance, seldom so used. Coindet 
of Geneva, first introduced this article into the materia 
medica. He recommends it as a powerful emmenagogue, 
for the cure of Bronchocele and Scrophula; Gimele has 
employed it in chronic leucorrhcea; Coster, of Paris, 
has used it successfully, in goitre; for the restoration of 
suppressed catamenia ; to produce this flux, when retained - 
beyond the proper age ; and to destroy a predisposition to 
scrofulous phthisis, to remove glandular congestions, of a 
cancerous or syphilitic character, for scrotulous 
ophthalmia and venereal ulcers, (in 1823) Rickwood cured 
4 cases of goitre with it; Mr. Callaway, surgeon, London, 
has cured several cases of scrofulous enlargements of glands 
of mesentery, with the tr. of iodine ; dose of tr. 10 drops 
3 times a day, increased to 20; ten drops contain one grain 
of iodine. ,
