of Iodine, and 109 parts of water until the odor of Iodine is 
no longer manifested. 
The clear liquid is then decanted and submitted to evapo- 
ration: at a certain degree of concentration, the Iodide is pro- 
duced in the form of red crystals, or the solution may be 
evaporated to dryness, and then sublimed in close vessels 
without decomposition. It may be made to combine with a 
new portion of Iodine. Water in large quantity dissolves it 
without any residue, but when digested with a small quantity 
it decomposes, forming hydriodic acid in solution and white 
crystalline scales, composed of water, acid, and iodide in 
variable proportions. Latterly it has been employed in 
Europe as a medicine. It is a powerful poison. An ex- 
temporaneous preparation combining the virtues of both of 
these active substances, has been used successfully in this 
city. It is formed of— 
Lugol's Solution of Iodine, gi. 
Fowler's " " Arsenic, ^iv. 
When mixed together in these proportions a change is ob- 
served in the appearance of the mixture, which is, in an in- 
stant, rendered almost colorless. The dose is five drops. 
Syrup of Morphia. 
Sulphate of Morphia gr. viij. 
Syrup " 8oz. 
Dissolve the Morphia in the^Syrup, with a few drops of 
diluted sulphuric acid. 
This is not an officinal preparation, and consequently pos- 
sesses a very indefinite character as found in the shops. As 
physicians occasionally prescribe it, it should be of deter- 
minate strength. The same discrepancy occurs in relation to 
the strength of the solution of morphia, although, officinal in 
the American Pharmacopoeia. In some parts of the country 
it is made in the proportion of 1 gr. to the ounce, as in this 
city, while in other places it is always made and understood 
to contain 8 grs. to the ounce. 
The proper strength of the syrup should be 1 gr. to the
