Mr. C. Jones spoke of the disagreeable effects of the odour of carbolic acid, and gave 
it as his opinion that the disinfecting power of that body was very inferior. 
The Secretary remarked that the antiseptic properties of carbolic acid could not be 
questioned, and he considered that this property indicated corresponding disinfectant 
qualities. 
The President thought the subject an important one, and deserved investigation. 
The lecture of the evening was “ On the Compounds of Mercury,” by Mr. Ed. Davies, 
E.C.S., who described the mode of manufaucture, properties, etc. of the principal phar¬ 
maceutical preparations of mercury, illustrating the subject by interesting and novel 
diagrams and experiments. A spirited discussion, sustained by several members, fol¬ 
lowed, and a vote of thanks passed to Mr. Davies for his very full and intelligent dis¬ 
course, after which the meeting was adjourned to January 4, 1868, the President, in 
doing so, wishing the members a merry Christmas. 
The sixth general meeting was held on the evening of January 4, 1866; Dr. J. B. 
Edwards, F.C.S., in the chair. 
After the transaction of some general business, a discussion took place respecting 
the cause of the change of colour of iodide of mercury, and cognate effects, between the 
Secretary, Mr. Murphy, Mr. Davies, and the Chairman. 
The Secretarv read a note from the Secretary of the Pharmaceutical Society, relating 
to the resolutions adopted at a former general meeting of the Association. 
Mr. Murphy laid before the meeting a sample of water from Harrogate, in which 
some abnormal components were lately discovered, and which rendered this water quite 
unique in its nature. The water was found to possess remarkable curative properties 
over many complaints, and it promised to prove a great boon to patients suffering from 
impaired digestion, loss of appetite, and the like. He gave a detailed tabulation of the 
analysis of the constituents of the water. 
Dr. Edwards exhibited specimens of bricks made by mixing intimately caustic lime, 
sand, and cinders in the ground state, pressing the mixture in moulds, ancl drying in the 
air. Calcination w'as dispensed with in the manufacture, and the bricks were stated to 
possess high refractory and other properties, which rendered them superior to the ordi¬ 
nary article used for buildings, etc. A discussion on the general fitness and usefulness oi 
the new bricks was sustained by Mr. Davies, Mr. Colby, the Chairman, and others. 
The Chairman exhibited experiments showing the power of Becquerel’s phospho¬ 
rescent tubes to emit monochromatic light in the dark after being exposed to strong 
actinic light, and described the materials in them, and also gave a concise discourse on 
the properties of light of different qualities. 
A vote of thanks to the Chairman concluded the business ot the evening.

Mr. Thomas Fairley, F.C.S., Lecturer on Chemistry at the Leeds School of Medicine,

Mr.Edward Brown read a paper upon “The Dispensing Chemist andhis Remuneration. 
After explaining the limits within which he proposed to confine his remarks, Mr. Brown 
alluded to the large number of chemists who gave up their calling for oilier engage-
