and considerable work was done. These excursions were made 

 as educational as possible, and particular pains were taken by the 

 leaders of the Club to assist students and leachers, of whom there 

 were nearly always a large number and who were most anxious 

 to learn. Full reports of these excursions were published in The 

 Naturalist from month to month throughout the summer. 



During the year the Botanical and Entomological branches 

 have held meetings at the homes of the members, the Botanical 

 branch having had twelve meetings and the Entomological eight 

 meetings. These have been very enjoyab'e and profitable to the 

 members. 



The Ottawa Naturalist has maintained its high standard,

 No less interesting will be Mr. Dovvling's address on the same 

 evening on the Newington Bog, which was visited by Mr. 

 Dowling and other members of the Club in the autumn and of 

 which Mr. Dowling has some good slides. 



The study of the circulation or diffusion of sap in plants has 

 engaged the attention of many scientists. On February 2nd, Mr. 

 F. T. Shutt, who has carried on some interesting experiments at 

 the Experimental Farm, will discuss this question. The address 

 should be of especial value to teachers and students. On the 

 same evening Dr. C. Guillet will read a paper entitled "Two
