ART. XXXIV.— ON THE PREPARATION AND USE OF THE 
SESQUI-IODIDE OF IRON. By Oberdcerffer, Pharmaceutist at 
Hamburg. 
The author proposed to replace for medicinal use, the prot- 
iodide of iron, which is very alterable, by the sesqui-iodide, 
which may be preserved for a long time without alteration, 
and which he obtains in the following manner. He causes 16 
grammes of iodine to act upon 6 grammes of iron in 32 
grammes of water, until the iodide of iron is formed; the li- 
quor is then filtered and diluted with 128 grammes of water 
and 8 grammes of iodine added, which readily dissolves ; 
finally, sufficient water is added to make up 320 grammes. 
Eight grammes of this medicine represent 43 centigrammes 
of iodine. It produces the same effects as the iodide, but is 
more active, and should be given internally in less doses. The 
best form for its use is that of syrups.
