casion. It enumerates a great many valuable preparations which were not contained in 
the London Pharmacopoeia. Most of these however, but not all, had come into pretty 
general use before they were made officinal. There was a novelty in the first British 
Pharmacopoeia which is retained in this. I refer to the directions for the preparation of 
most of the tinctures, by the maceration of the solid ingredients in three-fourths of the 
menstruum, with subsequent percolation and dilution to a definite measure. I have 
never heard to whom we were indebted for this plan, and I think that the author de¬ 
serves great credit for it. 
A distinguished member of our Association says that the Charta Epispastica will not 
raise a blister on the unbroken skin, and that it is only intended to keep open a blister 
previously made. My son made some of the paper for me, and, applying it to his own 
arm, found it to raise a very full blister. 
In the long and animated discussion which followed, Mr. Shaw objected to the altera¬ 
tion in the strength of essences. He considered that some expensive substances of 
doubtful value, as saffron, might have been omitted, and made some verbal criticisms on 
the language of the Pharmacopceia. He regretted that concentrated infusions had been 
omitted. 
Mr. Sharp said that Phillips’s authorized translation of former Pharmacopoeias con¬ 
tained as much detailed information as the new Pharmacopceia ; and opposed the use of 
concentrated infusions, as leading to uncertainty and fraud. 
The President stated that a member of the Edinburgh Chemists’ Association was 
present, and desired him to give some information with regard to pharmacy in Scot¬ 
land. 
Mr. Ainslie thanked the President for the kindly feeling which he had expressed, 
and spoke of the pleasure which he had derived from the paper and discussion. He 
considered that concentrated infusions were very valuable when prescriptions had to be 
dispensed in a short time, and that they were much used. He wished the Association 
success and prosperity. 
A warm discussion, in which several members joined, ensued as to the right of Phar¬ 
maceutists to use concentrated infusions, as they are not authorized preparations. 
The President then proposed a vote of thanks to Mr. Abraham, for his valuable and 
suggestive paper, which was carried by acclamation. 
LEEDS CHEMISTS’ ASSOCIATION. 
The Fifth Annual Meeting was held on the evening of Wednesday, October 9, 1867, 
in the library of the Philosophical Society ; the President, Mr. Thompson, in the chair. 
The Honorary Secretary, Mr. Yewdall, read the annual report of the Committee. 
This stated that a slight diminution in the number of members had taken place in the 
course of the year, but the usual number of meetings had been held during the session, 
when the following papers had been read :— 
On some Instances of Proposed Legislation affecting the Chemist, by the President. 
On the Importance of Study to the Chemist, by Mr. Smeeton. 
On the Common Objects of the Shop, by Mr. Reynolds. 
On the Desirability of Forming a Materia Medica Museum, by Mr. Yewdall ; and 
A Review of the Paris Codex, by Mr. Mayfield. 
The Report recapitulated the subjects of papers read in previous sessions, and referred 
to the other operations of the Association, such as courses of lectures that had been 
delivered upon chemistry and botany; and to the Library, as giving it strong claims upon 
the support of all chemists and druggists in the town. Especial allusion was made to 
the cabinet of Materia Medica specimens commenced by the Associates, aided by the 
donations of members; and kind contributions from Messrs. Maw and Son and the York 
Glass Company were acknowledged. 
The Treasurer’s account was then presented, and was as follows :—
