add the other ingredients, and make into a mass with water ; 
lastly, divide into 360 troches, (about 14 grs. in weight.) 
This will allow 2\ grains of the protocarbonate to each 
lozenge — six of which, (15 grs. of the iron,) taken in a day, 
constitute a regular dose. 
New Opodeldoc, or Liniment of hydriodate of Potash, 
Iodide of Potassium has been rendered highly valua- 
ble by its very successful application in glandular af- 
fections, and of late as an internal remedy in rheumatism. 
Externally, it is principally used in the form of an ointment, 
either alone or combined with an additional portion of 
iodine. 
Every one has observed the change this ointment under- 
goes from the re-action of the alkali, and the acid of the 
grease : the potassium becoming oxidized and the iodine set 
free, which colors the ointment yellow. 
In the Journal de Pharmacie et Chimie for April, of the 
present year, is published a formula for a solid liniment of Hy- 
driodate of Potash, intended as a substitute for the ointment of 
the same, which possesses the advantage of keeping a long 
time without becoming decomposed. It is called Baumi 
Hydriodate — and is prepared as follows : 
Iodide of Potassium, gj. I Soap of animal oil, giss.* 
Alcohol of 20°, giv. | Alcohol of 20° giv. 
Make these solutions separately — that of the soap upon a 
sand bath, assisted by a mild heat; when effected, mix the two 
together, aromatize with a small quantity of oil of lavender, 
and before it congeals, pour it into wide mouth vials. 
I have prepared some of it, and so far its appearance and 
uses have given general satisfaction. It resembles Steer's 
Opodeldoc, and, like it, when applied, melts by the natural heat 
of the body. 
*I have increased the quantity of soap from \ \ to 2 ounces to suit our 
Summer temperature.
