under the above name is made as follows. As this preparation is very liable to change, 
it should not be kept for any length of time:— 
5 drs. Ferri Sulph. 
6 drs. Sodse Phosph. 
192 grs. Quinse Sulph. 
q s. Acid. Sulph. Dil. 
q. s. Aquae Ammonise. 
6 grs. Strychnise. 
14 oz. Acid. Phosph. Dil. 
14 oz. Sacchar. Alb. 
Dissolve the Sulphate of Iron in 1 oz. of boiling water, and the Phosphate of Soda in 
2 oz. of boiling water. Mix the solutions, and wash the precipitated Phosphate of 
Iron till the washings are tasteless. With sufficient diluted Sulphuric Acid dissolve the 
Sulphate of Quinine in 2 oz. of water; precipitate the Quinine with Ammonia water, 
and carefully wash it. Dissolve the Phosphate of Iron and the Quinine thus obtained, as 
also the Strychnia, in the diluted Phosphoric Acid, then add the Sugar, and dissolve 
the whole without heat. The above syrup contains about 1 grain of Phosphate of 
Iron, 1 grain of Phosphate of Quinine, and of a grain of Strychnia in each drachm. 
(2.) Chlorodyne. In Mr. Squire’s ‘ Companion to the Pharmacopoeia,’ page 80, under 
“ Liquor Chloroformi Compositus,” will be found a formula which has been represented 
as the composition of this popular medicine. It is as follows:—“Chloroform, 4 oz.; 
Ether, 1 oz.; Rectified Spirit, 4 oz. ; Treacle, 4 oz. ; Extract of Liquorice, 2\ oz.; 
Muriate of Morphia, 8 grs.; Oil of Peppermint, 16 minims; Syrup, 174 oz.; Prussic 
Acid (2 per cent.), 2 oz. Dissolve the Muriate of Morphia and the Oil of Peppermint in 
the Rectified Spirit; mix the Chloroform and Ether with this solution; dissolve the 
Extract of Liquorice in the Syrup, and add the Treacle ; shake these two solutions toge¬ 
ther, and add the Prussic Acid ”

He states that, having prepared the pills with confection of roses, the pills in a short 
time exploded with evolution of considerable heat. Extract of gentian was afterwards 
used instead of the confection, but with a similar, although more feeble, result. He 
wishes to know the cause. , 
Oxide of silver holds its oxygen by a very weak affinity, and readily gives it up to 
substances such as morphia or essential oils, which absorb it with avidity, the action 
assuming the character of combustion. Permanganate of potash will sometimes act in 
the same way as oxide of silver. 
“ Chemicus ” (Dover).—We cannot advise in such a matter. The probable advantages 
of emigration would depend on circumstances of which we have no information. 
“ Chemicus” (Bath).—We recommend our correspondent to study, and pass the Minor 
Examination. The requisite information may be obtained from the Secretary, 17, 
Bloomsbury Square. 
T. A. (Wednesbury).—The information will be found in a little work just published, 
‘ Water Analysis,’ by Wanklyn and Chapman. 
11 Anxious.” —See the Amended Act, page 76. 
“St. Kilda ” (Gravesend).—Yes. 
A. P. S. (Liverpool).—The pills cannot be made according to the formula given. 
Suet, not bread, is necessary. See Yol. VII. (N. S.), page 615. 
“ Disp.” —As it is not probable that the resinous precipitate is intended to be applied 
to the skin, we should advise its separation from the lotion.
