A Committee of five gentlemen—Dr. Attfield, of London ; Mr. T. B. Groves, of 
Weymouth ; Mr. B. S. Proctor, of Grey Street, Newcastle; Mr. F. M. Rimmington, 
of Bradford ; and Mr. F. Sutton, of Bank Plain, Norwich—has the general charge of 
these subjects relating to the purity of medicines. Either member of the Committee 
will be glad to receive directly, or through the General Secretaries, authentic specimens 
of substances whose examination would tend to throw light on the questions. The 
analysis of such specimens will be free of cost. 
Every member of the British Pharmaceutical Conference is expected to suggest sub¬ 
jects for investigation, or to work upon subjects suggested by himself or by others, or to 
contribute information tending to throw light on questions relating to adulterations and 
impurities, or to collect and forward specimens whose examination would afford similar 
information, or in some other way to aid, in the advancement of pharmacy. Any new 
facts that are discovered during an investigation may be at once published" by an author 
at any meeting of a scientific society, or in any scientific journal, or in any other way 
he may desire. He is expected, however, to send a short report on the subject to the 
annual meeting. 
The current list of subjects requiring investigation is sent to members immediately 
after their election, and a new list immediately after every annual meeting. The list 
for 1863-64, containing several questions at present unaccepted, can be obtained of either 
of the Honorary General Secretaries—Dr. Attfield, 17, Bloomsbury Square, London, 
W.C., and Mr. R. Reynolds, F.C.S., 13, Briggate, Leeds ; or of the Local Secretary, Mr. 
J. C. Pooley, George Street, Bath. 
The annual meetings will probably be held at the time and place of the visit of the 
British Association. 
Gentlemen desiring to join the Conference must be nominated by two Members. The 
yearly subscription is five shillings, due in advance, on the 1st of July. 
The 1 Lancet ’ of March 5, 1864. in a leading article relating to the British Pharma¬ 
ceutical Conference, says :—“The utility of this movement is very obvious, aud we hope 
that the results attained may be commensurate with the energy and ambitious range of 
research with which the inquiry is inaugurated. In view of this extensive series of in¬ 
vestigations, and of the temporary derangement produced by the many changes, addi¬ 
tions, and errors of the new Pharmacopoeia, we shall suspend the operations of our 
Analytical Sanitary Commission.” 
MEETING AT BATH, MARCH 5, 1864. 
A committee to consider the subject of the prevention of accidental poisoning has been 
formed. It is under the sanction and recognition of the British Pharmaceutical Confer¬ 
ence, and is composed of Mr. J. R. King, of High Street, Bath ; Mr. J. II. Marsh, of 
Milsom Street, Bath ; and Mr. F. W. Kent, of Savi'le Row, Bath, either of whom will 
gladly receive suggestions on the subject. Such suggestions will be reported to a future 
meeting of the Committee, with the view of preparing a practical paper, to be read at the 
annual general meeting.
