 bodies which may be seen with 1-5 or 1-10 objective in the spu-

Out of 53 active members, 14 were present at this meeting 

 which was considered a very satisfactory commencement of the 

 fall camjjaign. So many of the members are unable to be pres- 

 ent habitually that it is proposed to report the sessions quite 

 fully in this i> riudical the coming year.
