ART. LXX. — CITRATE OF IRON AND MAGNESIA. 
By M.JVan der Corput ) with additional remarks by the Editor. 
The citrate of iron and magnesia appears likely to come 
into general use among ferruginous preparations, being easy 
of administration, and not liable to produce constipation. 
It is prepared by dissolving two parts, by weight, of recent- 
ly precipitated hydrated oxide of iron in a solution of three 
parts of citric acid : the liquor is then saturated with car- 
bonate of magnesia, and evaporated to dryness. The salt 
is in the form of shining brown scales; the taste is sweetish 
very slightly inky, and not at all disagreeable. It is per- 
fectly soluble in water ; it is not deliquescent, so that it may 
be prescribed in the form of a powder. It may be pre- 
scribed in doses of 15, 30, or 60 centigrammes (If, 5, or 10 
grains). 
Syrup of Citrate of Iron and Magnesia is prepared by 
dissolving S grammes in 15 grammes of orange-flower wa- 
ter, 'with 180 grammes of simple syrup. This is one of the 
most agreeable preparations of iron.
