bazaars is commonly very dark in colour ; the specimen before you has been re-distilled

Camphor of Peppermint. —Crystalline stearoptene of oil of peppermint, imported into 
India from China. A notice will be found of it in Christison and Pereira. It is, I fancy, 
obtained by freezing down the volatile oil obtained by the Chinese, who thus export the 
oil in two forms, solid and liquid. I think Pereira states that the stearoptene can be 
got also from the American oil, but not from the English. 
Camphor of Ajivan. —Stearoptene from the volatile oil of Ptychotis Ajwan —an Indian 
■drug (the plant) sometimes to be had in the London market. It smells very like Oleum 
Origani. An excellent account of it, by the late Dr. Haines, of Bombay, will be found 
in the ‘ Journal of the Chemical Society ’ of some years back. 
The liquid camphor possesses the same medicinal properties as solid camphor. The 
latter has been a common remedy with homoeopathists lately, in alcoholic solution, for 
cholera. I am not doctor enough to say of what value it is, but we are all chemists 
enough to know that the camphor must separate in the solid form immediately on its 
reaching the stomach. I would recommend the liquid camphor as possessing the pro¬ 
perty of maintaining its liquidity in the presence of water. 
The camphor of peppermint possesses the same properties as the oil of peppermint. 
I would recommend it as a substitute, in the oleo-saccharates, of which we have heard 
from Dr. Jackson this evening, and in other powders. 
Camphor of ajwan is a favourite carminative among the natives of India, and would 
probably be found as useful as the peppermint, if procurable here. 
To the best of my recollection the prices of these drugs in the Bombay bazaar are;— 
Kaladana, from.Is. to 2s. per lb. 
Cocum Oil, from. dd. „ Is. „ 
Liquid Camphor, from.2s. „ Is. „ 
Camphor of Peppermint, from .... 4s. „ Gs. per oz. 
Camphor of Ajwan, from.4s. to Gs. „ 
After some remarks, Dr. Scoresby-Jackson proposed a vote of thanks to Mr. Kemp for 
his communication and presentation to the Museum of the Society, which was carried 
unanimously.

“ TO THE PRESIDENT AND MEMBERS OF THE LEEDS CHEMISTS’ ASSOCIATION. 
“Gentlemen,—Through the Pharmaceutical Journal of this month, I became aware 
that your President (Mr. Thompson) had commented at considerable length and in an 
adverse spirit upon some passages from a letter of mine addressed to Mr. Ince, and 
quoted by that gentleman in his paper on ‘Pharmaceutical Ethics.’ 
“It was my intention to have had a paper on the subject, in readiness for the next 
meeting of your Society, but as I have just learned that you meet to-morrow, it is not 
possible to tind leisure at this time to do more than to refer you to the ‘Pharmaceutical 
Journal,’ vol. i. p. 17G, The Apothecaries’ Company v. Greenhough, 1842 ; vol.'vi. pp.
