desired the resuscitation of the Section. He referred to 
the practical importance of the subject, and hoped the 
matter would meet with the hearty co-operation and 
support of the members individually.

purpose, the amount to be limited to 5/- each, and he 
trusted the members would kindly help in the matter, 
however small the contribution.

officers and Committee for the current Session, as per 
printed cards which had already been distributed.
