The following gentlemen were then appointed the Officers of the Society:— President , 
Mr. M. Eogerson ; Vice-President , Mr. F. M. Rimmington; Treasurer , Mr. Thomas 
Harrison ; Hon. Secretary , Mr. Herbert G. Rogerson. Committee :—Mr. Francis Bell, 
Mr. J. Boast, Mr. Joseph Hick, Mr. W. Cockshot, Mr. R. Parkinson, Ph.D., Mr. J. 
Walker. 
Mr. F. M. Rimmington and Dr. Parkinson were deputed to negotiate with Mr. G. 
Ward, F.C.S., of Leeds, for the delivery of a series of lectures on Chemistry, having a 
direct bearing on the subject of Pharmacy, for the purpose of assisting students in pre¬ 
paring for the examinations of the Pharmaceutical Society. 
The first of a preliminary course of twelve weekly lectures on the “ Non-Metallic 
Elements” was delivered by Mr. Ward, in the Society’s room, on Monday evening, 
February 8th, to an audience numerically most promising and encouraging. 
The interest of the lecture was enhanced by a variety of instructive and pleasing ex¬ 
periments, familiar objects and substances being selected for illustration, and their nature 
and properties aptly and popularly explained. 
As the Society grows older, other desirable and useful measures will in all probability 
present themselves for its consideration, neither last nor least among which ranks the 
curtailment of the rather protracted business hours usually observed here, so that stu¬ 
dents may be enabled successfully to prosecute their labours; the leisure time offered 
under the present regime being inadequate to the requirements of systematic study. 
DUNDEE CHEMISTS AND DRUGGISTS’ ASSOCIATION. 
The usual monthly meeting of the Dundee Chemists and Druggists’ Association was 
held in Lamb’s Hotel on Wednesday evening, February 3rd, Mr. William Laird, Vice- 
President, in the chair. The paper for the evening was on “ Botany,” by Mr. Hender¬ 
son, which subject he treated in a concise and lucid manner. At the close of his paper 
Mr. Henderson intimated his intention of presenting to the junior members of the So¬ 
ciety a prize for the best collection of flowering plants gathered during the summer. 
This prize he meant as a stimulus to them to join at once the class about to be started 
for the prosecution of botany during the summer months; and as that science was one 
of the subjects for examination under the new Pharmacy Act, he trusted they would see 
the propriety of embracing the present favourable opportunity of making themselves 
proficient in such an important branch of their ordeal. He hoped to see a very full 
turn-out of members—juniors and seniors—at next meeting, when all arrangements 
could be made. One or two prizes for other subjects were spoken of, and will be brought 
forward in due time. Votes of thanks to the Chairman and to Mr. Henderson termi¬ 
nated the proceedings. 
LEEDS CHEMISTS’ ASSOCIATION. 
The Fourth Meeting of the Session was held at the Philosophical Hall on January 20, 
1869 ; the President, Mr. Reynolds, in the chair. 
The Hon. Sec., Mr. Ykwdall, announced that Mr. Harvey had very kindly offered a 
prize of one guinea for the best collection of dried Bri;ish plants made by Associates 
under twenty-one years of age between February 1 and November 1 of the present year ; 
the other conditions to be similar to those adopted by the Pharmaceutical Society. 
Stephenson and Churchill’s ‘ Medical Botany,’ in four volumes, was liberally presented 
by Messrs. Hirst, Brooke, and Hirst. 
Mr. J. Chapman Wilson, F.C.S., read the paper of the evening upon “Potable 
Waters.” This was an interesting essay upon water supply in its various aspects, and 
noticed some facts of considerable local interest. Thus, at present, Leeds has a water 
supply of 8° to 10° of hardness on Clark’s scale; but a new scheme is being carried out 
which will give a water of 4° to 5° of hardness. It is true that peat stain may be pre¬ 
sent in the new supply, but the lecturer regarded this as not unwholesome, and he was 
convinced that Spencer’s process of filtration through “magnetic carbide of iron” would 
entirely remove the unsightly appearance.
