[26.] —DOSE OF CHLORAL HYDRATE.—The dose 
of chloral hydrate varies very much as to quantity. In a 
patient this week, to whom I prescribed it, 50 grains had no 
•effect; but by pushing it to 75 grains, excellent, and most 
invigorating sleep was procured.—C harles Kidd, M.D. 
[29.]— QUININE MIXTURE.—If A: P. S. will try ext. 
cinchonas liq. B. P. with sarsaparilla, he will probably be more 
successful than with quinine alone; the following produces 
an elegant mixture :—■ 
Decoct. Sarsae Co. Cone. 5 parts 
Ext. Cinchon. Liq. B.P. 2 „ 
Sp. Yini Rect. . . . 3 „ 
Tinct. Quinae Co. . f 2 „ 
Syr. Aurantii .... 4 „ 
Mix. Dose 5i to 5U» water. 
If dandelion be desired, some of the succus tarax. B. P. may 
be added, but then the mixture is not quite clear.—J. H. 
Baldock, S. Norwood. 
[33.]—DISPENSING. 
R. Tinet. Quinim Co. §iss 
Ammon. Carb. gr. 1 
Syrup. Aurantii 3ss 
Aquae $j. 
M. ft. mist. 
Mix the tinct. quinae co. and sjw. aurantii. Dissolve the 
aminon. ses. carb. in the aqua, and add this last to the tinc¬ 
ture ; an opalescent mixture is obtained, but no appreciable 
precipitate, which is?m£ the case if the conditions be reversed. 
In either case, however, a thick mixture, with deposition of 
quinine, is the ultimate result.—J. H. Baldock, S. Nor- 
ivood. 
[35.]—ROSE TOOTH POWDER.—Add 9i of carmine 
to each pound of precipitated chalk, well rubbing it with a 
little of the chalk first. The more it is rubbed, the more the 
colour is developed.—J. H. Baldock, Norwood. 
.[36.]—EAU DE COLOGNE.—J?. Shakerley (Liskeard) 
will find the following a good recipe for making Eau de 
Cologne:—

Musk gr. x 
Orange Flower Water Oj 
Rectified Spirit of Wine Oxiij 
Macerate for fourteen days and filter.—J. F., Aberdeen. 
[38.]—SOLUBILITY OF CITRATE OF IRON.—In 
answer to J. L. (Birmingham) T. H. (Bideford) writes,—■“ I 
frequently have to make up prescriptions, written by an 
eminent physician of a neighbouring town, in which citrate 
of iron is ordered; but as I never allow any in my shop to 
■substitute one medicine for another, and knowing how little 
soluble citrate of iron is in cold water, I always have it put 
into a test-tube with distilled water and dissolved over the 
gas, which only takes a short time, and then forms an ele¬ 
gant mixture.” 
[42.] —CHILBLAINS.—In answer to “ Lugoney ” and C. 
Bennett , “ Utile ” (Boston) says that the following makes an 
■excellent chilblain lotion:— 
R. Glycerine 5iij 
Arnica Root gj 
Spirit of Camphor 5ss

Rectified Spirit of Wine *ij. M. 
This composition to be put into a bottle 8 or 10 inches in 
length and about f-inch in diameter, and the mouth covered 
with perforated bladder. 
The following are the changes which may be observed:— 
If the weather promise to be fine, the insoluble matter will 
settle at the bottom of the tube, while the liquid remains 
pellucid; but previous to a change for rain, the compound 
will gradually rise, the fluid remaining transparent. 
Twenty-four hours before a storm or very high wind, the 
substance will be partly on the surface of the liquid, appa¬ 
rently in the form of a leaf, the fluid in such case will be very 
turbid and in a state resembling fermentation.—W. J. Wat- 
kinson, Preston. 
[51.]—BRILLIANTINE. 
Honey 5j 
Glycerine 3SS 
Eau de Cologne 35s 
Rectified Spirit of Wine 31].

The following is another formula:—

Absolute Alcohol, 6 parts.

[55.]— OIL AND COTTON CAKE.— D. Jenkins (Bridg¬ 
end) wishes to know the best form of giving oil and cotton 
cake. 
[56.] —HAIR WASH.— “Alumen” (Bayswater) asks for 
a formula for a good inexpensive hair wash, one that will 
have a clean appearance.

water, or tell him where to procure it.

walnuts in good condition ?—Iodi. 
[59.] —DISPENSING,—What is the best way of preparing 
the enclosed prescription ? I have prepared it several times,

being thrown down.— Magnesia. 
R. Quin® Sulph. gr. xij

Magnes. Sulph. 3iss 
Tinct. Zingiber. Siss 
Aquce ad 3VJ 
M. ft. mist. 
A tablespoonful in water twice a day after food. 
[60.]—CHEMICAL CABINETS.—IIow does the Phar¬ 
macy Act affect the sale of chemical cabinets P They mostly 
contain one or two chemicals, such as sulpho-cyanide of po¬ 
tassium, corrosive sublimate, or prussiate of potash, which 
come within Part I. of the Schedule A. of the Poisons Act, 
and require registration before sale, and yet this, I think, is 
never done. I am anxious to know if I can bring out a new 
chemical cabinet which should contain the above.—E. J. B. 
It would not be legal to sell poisons in chemical cabi¬ 
nets, except in accordance with the provisions ot the Act. 
Sulphocyanide of potassium and prussiate ot potash are not 
poisons.—E d. Pii. J.]
