dissolved in two kilogrammes of boiling water. The lime is 
precipitated by oxalic acid, and the filtered liquid containing 
the lactic acid, heated in contact with iron filings for six or 
eight hours, when, upon cooling the filtered liquors, the lac- 
tate of iron is furnished. 
The malate of the protoxide of iron, officinal in the Pharm. 
Pruss. under the name of Extraction Ferri Pomatum, is 
prepared by digesting one part of iron nails, or wire, together 
with four parts of the juice of apples, for some days, then 
evaporating the liquid to one-half, filtering, and concentrating 
to the thickness of an extract. 
The inconstant nature of the class of ferruginous wines has 
not escaped the observation of medical writers. A long time 
ago a Mr. Parmentier suggested the propriety of substituting 
a wine of more definite character, to be made from a certain 
proportion of liquid tartrate of iron and potash, holding in so- 
lution a fixed quantity of the salt. 
Reference is made to a preparation of this kind in nearly 
all the French works treating of Pharmacy, under the name 
of " Teinture de mars tartariseeP 
Virey directs one oz. of this tincture to be added to a pound 
of white wine. 
A very valuable preparation of iron very little known 
here, though sometimes prescribed by foreign practitioners, 
is the Bestucheff's Tincture, much used and highly esteemed 
in Germany, and also in France, where it is sometimes known 
under the name of General Lamotte's Drops. 
Its synonyms are — Guttse Vervina?, Etherial Tincture of 
Iron, Liquor Anodynus martialis, Elixir d'or. 
Proto-hydrochlorate of Iron, deliquescent, 1 part. 
(Made by treating iron filings with sufficient hydrochloric 
acid to dissolve the metal, evaporating to dryness, and leav- 
ing the chloride, thus obtained, fall into deliquescence.) 
Sulphuric Ether, 2 parts.
