information among members of the trade and students. 
In order to facilitate reference , correspondents are re-

[18.]—RUBINI’S CAMPHOR.—In regal’d to J. Botham's 
query, tlie following formula will be found successful:— 
R. Alcohol, 1 part by measure. 
Camphor, 1 part by weight. 
Let the alcohol be prepared in the following way:— 
Take of S. Y. R. *xx. 
Pot. Sub. Carb. ^j. 
Digest for 24 hours, and pour off the supernatant liquor, 
rejecting the residue.—J. T. R., Warrington. 
[21.j—GLYCERINE JELLY.—In answer to B. W. W. 
(Sheffield), AT. Q. Z. sends the following recipe for the 
above:— 
[32.]—DENTISTRY.— S. S. will find all the necessary 
information with reference to diploma, or rather certificate of 
qualification in dental surgery, under the heading “ Royal 
College of Surgeons, England,” in the London and Provin¬ 
cial Medical Directory, by Churchill, which he can generally 
borrow of any practitioner of standing. Tome’s ‘Dental 
Surgery,’ by Churchill and Sons, is the best Manual.— 
L. A. S. A. 
SYRUPUS EERRI QUINCE ET STRYCHNLE 
PIIOSPHATUM (Easton’s).—Mr. Squire’s formula for the 
above preparation, as recommended to “ Dispenser ” in last 
week s Journal, has two objections. First, the quin® sulphas 
is ordered to be added along with the precipitated ferrous 
phosphate and strychnine to the diluted phosphoric acid, in¬ 
stead of being converted into phosphate, which can readily 
be done by sodium phosphate in the same way as the other. 
The second objection is, the absence of sodium acetate inva¬ 
riably used in this and similar preparations, to ensure the 
occurrence of acetic acid in the solution,—sulphuric acid 
being a solvent of ferrous phosphate, while acetic acid is not. 
Let any one make the ferrous phosphate with and without 
the sodium acetate, and the advantage in favour of the latter 
will be at once apparent. In other respects the formula is 
good.—W. Robertson, 177, High Street , Elgin. 
[*** Our correspondent “Dispenser ” specified the formula 
given by Mr. Squire, which was therefore supplied.— Ed. 
Ph. J.] 
White soft soap 
Pure glycerine 
Almond oil. . 
Otto of thyme. 
. 4 oz. 
• 6 „ 
C 3 lbs. in summer. 
' (_ 4 ,, in winter. 
. 2 drachms. 
QUILLAI BARK.—In answer to A. Z ., quillai or soap 
bark is the produce of the Quillaia saponaria, a rosaceous 
tree growing in South America, and there used as a sub¬ 
stitute for soap. It has been used as a hair wash in this 
country. 
Mix the soap and glycerine in a mortar, add the perfume to 
(the oil, and rub it in gradually, taking care not to add the 
•oil faster than it can be incorporated, or the result will not 
have the jelly-like appearance required. 
[23.]—COLOURING FOR POMADE.—A preparation 
•called “ Aureoleinc,” made by Mr. Baldock, South Norwood, 
for the last six years, will fully answer the purpose intended, 
as it will stand exposure in the window for at least twelve 
months without fading. 
If S. W. S. (Hull) will send his card to Mr. Henry H. 
Pollard, 140, High Street, Ryde, I.W., that gentleman will 
-communicate with him respecting colouring for Pomades. 
[25.]—FUMIGATION.—Generate chlorine by adding 
dilute hydrochloric acid to chlorinated lime placed in open 
dishes; or, equally good, disinfect with sulphurous acid gas, 
by burning sulphur in the form of match or in an open pan. 
Doors, windows and other outlets ought to be kept closed 
during the process of disinfection, and all polished steel or 
gilt furniture removed.—L. A. S. A. 
[33.]—DISPENSING.—Will some of your readers kindly 
give me their opinion as to the best method of dispensing the 
following prescription, and the appearance it should present 
when completed:— 
R. Tr. Quini® Co. . . . §iss 
Ammon. Carbon. . . gr. 1 
Syrup. Aurantii . . . 5 SS 
Aqu®.gi. 
M. ft. Mist. H. K. 
[34.]— J. W. will be glad of a formula for making aq. 
camphor® concent., B.P., extemporaneously. 
[35.]—ROSE TOOTH-POWDER.—What is the best- 
method of making rose tooth-powder so as to give a good 
pink colour ?— E. H. 
[36.]—EAU DE COLOGNE.— B. Shakerley (Liskeard) 
wishes for a good recipe for making Eau de Cologne. 
[37.]—EAU DE PORTUGAL.—A correspondent wishes 
to know the composition of Eau de Portugal. 
[26.]—CHLORAL HYDRATE is given, to allay pain 
and produce sleep, in doses from 10 to 120 grains : 30 is the 
ordinary dose.— F. Goodwin. 
[*#* 10 to 30 is the ordinary dose.— Ed. Pit. J.] 
[27.]—BENZINE.—A petroleum licence must be ob¬ 
tained. Generally the magistrates or other local authority 
will grant a licence to store a quantity not exceeding two 
gallons, if the case is properly explained to them. Applica¬ 
tion should be made, in the first instance, to the clerk to 
such authority.—L. A. S. A. 
[28.]—SYMPATHETIC INK.—A solution of proto-ni¬ 
trate of mercury developes black either by heat or the appli¬ 
cation of an alkaline solution, as lime-water. Glazed paper 
should not be used for secret writing, or it will be more or 
less visible on the surface. Rolled demy is better than ordi¬ 
nary note-paper.—J. Whitfield, Scarborough. 
J. H. B. will find that by writing with the following solu¬ 
tion and applying heat, the writing will become perfectly 
black:— 
R. Cupri Chlor.5i 
Aqu® Dest.5ij. 
Ft. Sol. 
—A. J. Lance. 
[29.]—QUININE MIXTURE.—Most trade fonnul® 
contain only a trace of quinine, and a more appreciable pro¬ 
portion of chiretta. Quinine, producing a bulky sediment 
with sarsaparilla, is not much used in the combination.— 
^Simon Pure. 
[38.]—SOLUBILITY OF FERRI CITRAS.—No doubt 
others have experienced the same difficulty as myself trying 
to dissolve in water, and sometimes in an acid mixture, ferri 
citras; and although many years have elapsed since the 
difficulty was remedied by the addition of ammonia or car¬ 
bonate of ammonia, and finally the ammonio-citrate of iron 
became well known and generally prescribed, yet there are 
medical men now who continue to order the insoluble com¬ 
pound. I suppose they are not aware of its insolubility; 
and some of my friends, when spoken to on the subject, 
have readily altered it to the ammonio-citrate. But some¬ 
times a prescription is presented containing the salt, and 
we have no opportunity of consulting the writer, nor of 
knowing how it was previously dispensed. It would be 
better for the profession to adhere as much as possible to the 
Pharmacopoeia, and then w r e should know what is meant. I 
have generally put the ammonio-citrate w hen the citrate has 
been ordered, but not always. What do you advise?—J. L., 
Birmingham, Nov. 7, 1870. 
I*X* In a case of this kind w r e could not undertake to ad¬ 
vise, but w r e believe the general practice is to use the solublo 
preparation.—E d. Ph. J.]
