twenty-four hours (frequently stirring) in a gentle heat; filter the 
liquid, and neutralise any excess of acid by dropping in, gradually, sp. 
amnion, arom., until it is saturated. The liquid is of a reddish brown 
color, not precipitated by alkalies, nor altered in color by the ferrocya- 
nide of potassium, or tincture of galls. The taste is slightly styptic, 
though not unpleasant. It will be seen that there are two equivalents 
of acid, citric, combined with one equivalent of potassa, and one equiva- 
lent of the ferri sesquioxyd. — One drachm of this solution contains five 
grains of the dry ferri potassio-citras. 
An agreeable syrup may be made by dissolving sacchar. alt., lb. j. 
in f^xviij. of the solution, and liquifying by a gentle heat. We have 
thus f^xviij. of syrup; consequently fgj. will contain 2.25 grains. —
