and pointed to a second period of glaciation, as he had observed the 

 debris of these resting directly upon sti-atified mai'ine deposits, which 

 are themselves underlaid by glacial "till" or clay. 



Mr. Ami had examined the region mentioned, and believed those 

 deposits to be much more recent. They were correllated with the 

 " Ottawa gravels," which are met with at Britannia, Rochesterville, 

 Lansdowne Park, Gilmour's Mills, <tc., and which mark a period of 

 time subsequent to the " Leda Clay " formation, a period of lake basins 

 and wide river expansion, which has since been gradually diminishing 

 until the present river flows. 



Dr. Ells had also seen them, and believed they were formed along 

 the shores of rivers and pointed to similar ridges in process of formation 

 in the St. Lawrence below Quebec. Dr. Ells, Dr. Small, Messrs. J. Bal- 

 lantyne,and R, B. Whyte, besides the lecturer, took part in the discussion. 



The fourth lecture, on February 4th, was by Mr. J . Fletcher upon 

 Entomology. The value of the study as a practical branch of agricul- 

 ture was shown ; the different classes of injurious and beneficial insects 

 were described, and the mode of application of some of the remedies for 

 injurious kinds was explained. The fifth lecture, on January 11th, 

 was given by Mr. W. H. Hai-rington upon the same subject. The structure 

 and classification of insects were dealt with and the reasons for dividinsj 

 insects into the different orders were explained in a clear and intelligible 

 manner. Mr. Harrington also gave some valuable suggestions as to 

 the best way to collect and study insects. The animated discussion at 

 the termination of the lecture showed the high appreciation by the 

 audience of Mr. Harrington's address. 



Of our Monday afternoon lectures the one looked forward to with 

 perhaps the most interest was that of the 18th of February, on Zoology 

 by the Rev. G. W. Taylor, of Billings Bridge, late of Victoria, B. C. 

 Mr. Taylor has been a member of the club since 1884, and although 

 so far beyond the field of its operations, has always taken a deep interest 

 ill its work and welfare. He is an ardent lover of Natui'e and an 

 authority in several sciences, particularly in Entomology and Conchol- 

 ovy. He has lately removed to Ottawa, and the council recognizes iu 

 liim a Valuable acquisition to our list of active members.
