slight precipitation that might otherwise occur when the wine was exposed to strong 
sunlight. The formula proposed was as follows :— 
Ammonio-citrate of Iron.160 grains. 
Crystalline Citrate of Ammonia .... 60 ,, 
Sherry. 1 pint. 
The wine thus prepared was perfectly transparent, and had no disagreeable taste.” 
“ ON COMMERCIAL WINE OF IRON, WITH SUGGESTIONS. BY F. SUTTON, F.C.S. 
[Abstract .] 
“ Steel wine is well known to vary much in strength. The author obtained seven 
samples from the leading Pharmaceutical Chemists in London, and estimated the per¬ 
centage quantity of iron in them, and also the amount of saccharine residue they 
yielded on evaporation to dryness. The following table exhibits the results of the 
experiment:—

“No. 5 was made with tartarated iron. The composition of the rest shows that the 
less saccharine residue, a specimen of sherry, yields on being evaporated to dryness, 
the more iron it is capable of dissolving. The metal should be digested in light 
sound sherry for four months, to obtain the best preparation. 
“ The examination of a number of samples made with tartarated iron, showed that 
they contained about one, instead of one and three-quarter grains of iron, the rest 
having precipitated. The author thought that if a strong, sound sherry were used, 
and the ingredients allowed to remain in contact for one month, access of ah’ to the 
vessel being occasionally allowed, a satisfactory preparation could be made by the 
process.” 
Mr. Merrikin and Mr. Robbins spoke of the advantage of adding tartaric acid 
or bitartrate of potash to the wine when making it by the old plan from iron wire. 
The first-named speaker had found the preparation of the B. P. very unsatisfactory, 
being returned by customers with complaints that it became muddy. 
The President and Mr. D. Hanbury also condemned the new formula, and ex¬ 
pressed the opinion that the old preparation must still be kept in hand. 
Mr. Abraham differed from these opinions, and thought that the new preparation 
kept well, whilst he objected to the old one that it retained the flavour of the hydro¬ 
gen-oil, and often lost its colour so much that caramel had been used to replace it. 
Mr. T. B. Groves thought that hydrated oxide of iron and citric acid might be 
used. 
Mr. Reynolds queried if Ferrum Redactum would not be a convenient form of in¬ 
troducing a uniform amount of iron.

QUININE. BY MR. J. C. BRAITHWAITE.

tc The author had examined fifteen samples of this medicine, which should contain 
sixteen per cent, of quinine, or about twenty-five per cent, of citrate of quinine. The 
following is a tabular form of his results :—
