THE LECTURE COURSE. 



The joint course of Lectures under the auspices of the Ottawa 

 Literary and Scientific Society and of the Ottawa Field 

 Naturalists' Club is now over and a brief synopsis is given 

 of the events as they took place. 



By kind permission of the Hon. G. W. Ross, Minister of 

 Education for Ontario, and of Dr. J. A. MacCabe, Principal of 

 the Provincial Normal School, Ottawa, the hall was again placed 

 at our disposal for the said course of free public lectures. The 

 following comprise the series of evening soirees : 



November 9TH, 1896. — On this evening between 8 and 

 10.30 p.m. was held a Conversazione and Microscopical Soiree at 

 which Principal MacCabe, Mr. Shutt, Mr. Klotz, ond Mr. A. H^ 

 Macdougall gave brief addresses. These were followed by five- 

 minute talks on Natural History, illustrated with microscopic 

 slides thrown upon a white screen by means of an electric pro- 

 jection microscope furnished for the occasion by Mr. H. M. Ami. 

 This method of presenting microscopical objects before so 

 vast an audience as was present on that occasion proved most 

 interesting and satisfactory. Dr. Fletcher spoke on insects and 

 plants ; Mr. Odell on living organisms in water ; Prof Prince 

 on various Zoological and Anatomical preparations whilst Dr. 

 Ami introduced thin sections of corals and rocks and spoke 

 briefly upon their structure and characters.
