LIVERPOOL CHEMISTS’ ASSOCIATION. 
The Tenth General Meeting of the Session was held 
at the Royal Institution on Thursday evening, the 30th 
March’; the President, Mr. John Abraham in the chair. 
Donations of periodicals to the Library were an¬ 
nounced, and votes of thanks accorded to the donors. 
Mr. S. G. Hilditch called attention to the presence of 
phosphate of lime in animal charcoal. He thought the 
formula given in the Pharmacopoeia for the manufacture 
of pure animal charcoal was incomplete, and suggested 
the necessity of testing for phosphate of lime before using 
it for chemical investigation. He promised to make 
further experiments and report at a future meeting. 
Mr. E. Davies, F.C.S., had made several experiments, 
and found it was not an easy matter to rid the animal 
charcoal of this impurity. 
The paper for the evening, on “The Nomenclature of 
the Natural Sciences,” by Mr. Charles Symes, Ph.D., 
etc., was read by Mr. Alfred H. Mason, F.C.S., in the 
unavoidable absence of the author. 
Mr. E. Davies, F.C.S., was glad to find that the 
science with which he was associated had merited praise 
from Dr. Symes for its system of nomenclature; there 
had not been so many difficulties to contend with as in 
some of the other sciences, as old names were changed 
before the great mass of new chemicals were introduced. 
He thought it would be a difficult matter to alter no¬ 
menclature, and in some cases not desirable. Take 
British Ferns, for instance, with their many varieties, 
alteration would not make their nomenclature more ex¬ 
pressive. Mineralogists had the greatest difficulties to 
contend with; and it was there, where reform was most 
wanted, he thought it would be unwise to make changes 
upon individual authority. 
The President thought some minerals might be de¬ 
scribed by their chemical composition. He could not 
see any objection to the nomenclature of diatoms being 
associated with the name of the first exhibiter of them. 
Speaking of chemistry, he regretted to note the changes 
in nomenclature which had taken place of late years; 
take, for instance, chlorides of mercury. Chemists dif¬ 
fered in their nomenclature; for instance, sulphate of 
soda might be called sulphate of soda, sulphate of sodium 
or sodic sulphate. 
Mr. Davies thought the change in chlorides of mer¬ 
cury was a very desirable one, as we now had definitely 
mercuric chloride and mercurous chloride. 
The Secretary was instructed to convey a unanimous 
vote of thanks to Dr. Symes for his paper and the meet¬ 
ing closed.

NOTICE. —To prevent delay, correspondents are re¬

lishers. 
[186.]—BAKING POWDER.—I see in your number for 
March 11th that “ Farina" wishes for a good form for 
baking powder. The following is one I can confidently re¬ 
commend, as I frequently have pastry, etc. made from it, be¬ 
sides which it is inexpensive. 
R. Sodoe Cai-b. Exsicc. S v hj 
Acid. Tart. Exsicc. 5 v j 
Pulv. Curcumae 5j

Mix. The soda and acid must be properly dried before 
mixing the other ingredients, otherwise the powder spoils by 
keeping. To be kept in stoppered bottles.—A. T. Girdler. 
[193.]—LIQ. OPII SEDATIVUS.—An excellent formula 
for the above is given by Mr. T. B. Groves, F.C.S., in the 
Pharmaceutical Journal for January, 1869; but, as 
some readers may not be able to refer to it, I send an abridg¬ 
ment. 
Opium, in coarse powder, 1^ oz. 
Prepared Chalk, £ oz. 
Rectified Spirit, 5 oz. (f.) 
Distilled Water, q. s. 
Boil gently for half an hour the opium and chalk with one 
pint of distilled water; filter; w r ash up to 15 oz. and add the 
spirit. After a few days’ repose filter again. It improves by 
keeping. Of course, the finer the opium the better the 
liquor. This is of the same strength as tr. opii, B. P.—A. P. 
Baker. 
CONDITION POWDER. 
Take of Fenugreek, in powder, 16 parts. 
Sulphur, in powder, 8 parts. 
Cream Tartar,

kindly inform me how they would prepare it? —G. C. Allen. 
[221.]—SULPHATE OF LIME.—Can any commercial 
use be made of the sulphate of lime left after making the 
carbonic acid gas ?—N. 
[222.]—TINCT. COLOCYNTH.— J. S. would like to be

[223.]—LIQUID GOLD.—Will any reader inform me 
how to make a liquid gold for lettering on metal ?—C. J. B.
