THE CHEMIST AND DRUGGIST 
October 5, 1895 
156/9. M, C. C . — Your inference is correct. 
156/15. Edclid is going up for his Minor shortly, and is 
troubled about what kind of Percentage Solution the ex- 
aminers prefer, i e. : — (1) Weigh solids, measure liquids, and 
calculate parts by weight in like parts by measure, as 
1 gr. by weight in 100 fl. gr. ; (2) calculate them as 
logically true percentage — i.c., everything by weight — as 
1 gr. by weight in 100 gr. weight ; (3) base the calcu • 
lation upon minims, as 1 grain by weight in 100 minims. 
[0n page 219 of our Diary for the present year we give 
a table for use at the dispensing-counter. We understand, 
however, that the examiners, following the B.P. plan, prefer 
grains and fluid grains, and this is all right except when the 
solution is measured by minims (as in the case of hypodermic 
solutions). We have repeatedly stated that the second 
method above mentioned is ridiculous and logically untrue 
when applied to medicine in this country.] 
155/74. Blue Bottle . — You will find a formula for Whit- 
worth Red Bottle in the 1894 Diary, page 383. Note 
that the label is liable to stamp-duty. 
146/41. Balfiess — Dr. Horn informs us that the pre- 
scription for Hair-lotion is as follows : — 
Liq. carb. deterg. ,, 3iv, 
Boracis Sss. 
Glycerini 3 j. 
Aq. mell 2 j.

!M. Ft. lotio. 
155/28. Biirt . — We quote the following from Squire's 
“Companion”: — Aq. flor. anthem, flowers, 1; water, 20; 
distil 10. 
153/72. Chloral , — The following will make as palatable a 
dose of the Neuralgic Mixture as you can get : — 
Butyl chloral hydratis gr. v. 
Glycerini Ulxv. 
Triturate for several minutes, and slowly add the following, previously 
mixed : — 
Tr. gelsemii iqx, 
Aq. chloroform, ad |j. 
153/49. TV. 2V. T . — Heading for Beer. — See C. Sc D., 
May 11, 1895, page 671. 
153/71. S, R. N. — (1) Soluble Infants’-food: —

Malt extract in powder 2 
Condensed milk „ 1 
Sugar of milk „ ,, 1 
Mix, 
(2) Lemon Squash : —

Citric acid gj. 
Water Sxxiv. 
Dissolve and add the following, previously mixed and filtered : — 
Salicylic acid 5 ss. 
Oil of lemon . r - , r 5ss. 
Tincture of lemon-peel 
Tincture of turmeric 3 ss. 
Caramel iqxx 
Shake up the tincture of lemon with the oil now and then 
during four hours ; allow the oil to separate, decant the tinc- 
ture from it, mix the tincture with the other ingredients, 
and filter. 
151/65, A. P. Q , — The system is genuine as far as it 
goes, but we are not in a position to say more about it. 
153/54. Pyro . — The eggs iu B.P.C. Cod liver-oil Emul- 
sion are the cause of it going bad. The best way to prevent 
this is to add 3 oz. of brandy to each pint, but even then it 
is not desirable to keep it more than six weeks. Salicylic 
acid, 1 gr. to the ounce, also helps to keep it, but we advise 
you to adopt rather a pure gum-acacia emuldou such as that 
described in the C. April 6, 1895, page 435, which ap- 
pears to us to be excellent. 
153/24. J. B. 8 —In formula for Combined Bath 
(f7 4' B , September 21, 1895) for 8 oz. read 8 pints. Prints 
are usually washed before using this bath, although we know 
some who prefer to put photographs straight into the bath 
without any previous washing. 
156/71. Trwyn . — We do not know the apparatus to which 
you refer. Your best plan is to consult a specialist on diseases 
of the nose. 
156/66. Salophen . — Carbonate of ammonia is given for 
calcined hartshorn powder. 
116/9. Emulsion — Please say what kind of cod-liver oil 
emulsion you want, and what dozen formulas yen have tried,, 
and do not like.

Errard’s Tooth-forceps . — Mr G. Burch (West Bromwich)' 
informs us that Mr. Errard died five or six years ago, and 
the forceps are, in consequence, no longer made. 
In reply to the same query, “Who makes Errard’s tooth- 
forceps 7 ” Mr. John Banhs (11 Aldersgate Street, E.C.) states- 
that the name should be Everard, not Errard. He adds that 
Mr. Everard has been dead for many years. He formerly 
lived in Goodge Street, Tottenham Court Road, and was 
maker of tooth-forceps for the late Sir Charles Tomes ; his 
work has not been surpassed since his death. He was a 
perfect artist, and although the forceps now sold in the 
trade are of the highest order, they do not at all compare in. 
design and finish with his.
