SYRUP OF PROTO-NITRATE OF IRON. 
315 
Take of Iron Wire (card teeth) in pieces, two ounces. 
Nitric Acid (sp. gr. 1.42) three fluid ounces. 
Water, thirteen fluid ounces. 
Sugar, in powder, two pounds. 
Put the iron in a wide mouthed bottle kept cool by standing in cold 
water, and pour upon it three fluid ounces of water. Then mix the 
acid with ten fluid ounces of water, and add the mixture in portions 
of half a fluid ounce to the iron, agitating frequently until the acid 
is saturated, using litmus paper. When all the acid has been 
combined, filter the solution into a bottle containing the sugar and 
marked to contain thirty fluid ounces. If the whole does not 
measure that bulk, pour water on the filter until it does. When 
all the sugar is dissolved, strain, if necessary, and introduce the 
syrup into suitable vials and seal them.* 
SYRUP OF PROTO-NITRATE OF IRON. 
By "W. W. D. Livermore. 
Syrup of proto-nitrate of Iron is an improved form, in which the 
officinal Liq. Ferri Nitratis is at present prescribed by several 
prominent physicians in this city ; and combining as it does the 
advantages of the proto-salts of iron, with stability of preparation, 
is destined to come into general use as an active and pleasant fer- 
ruginous remedy. I believe no formula for it has yet been publish- 
ed, and as apothecaries have found it both inconvenient and dis- 
agreeable depending upon others to prepare it by some secret 
recipe, the subjoined may be found a convenience.

the same result is arrived at by different processes, both are inserted. — Ed.
