ANNIVERSARY ADDRESS. 13 



Council marked benefits to the Society will be ensured. Another 

 alteration in our Bye-Laws, made at the same time, provides for 

 the oflice of President being tenable for two years in succession 

 instead of one year only. It was felt that cases may arise where 

 such a provision will be of absolute benefit to the Society and its 

 working. 



Conversazione. — On 10th December last the Society held a 

 Conversazione in the Great Hall of the University which was, as 

 usual, largely attended. In addition to numerous exhibits in 

 Science and Art a special feature, which proved of great attraction 

 to visitors, was the throwing open by the Professors of their 

 Chemical, Physical, Engineering and Biological Laboratories. The 

 new Chemical Laboratory replete with all modern appliances for 

 teaching chemistry in all its branches, was open for the first time 

 to public inspection. Experiments conducted in the different 

 Laboratories by the Professors and their assistants were highly 

 appreciated, and special thanks are due to these gentlemen. 



The series of star photographs shown by Mr. Russell, b.a., 

 c.m.g., f.r.s., were of great interest and much admired. 



In Bacteriology Dr. Camac Wilkinson, a former pupil of 

 Professor Koch in Berlin, attracted considerable attention by his 

 exhibits of from 60 to 70 pure cultures in various media, chiefly 

 gelatine-peptone glycerine, and agar-peptone. Pure growths of 

 diphtheria bacillus, of bacillus of Glanders, and several cultures 

 of Koch's comma bacillus of Asiatic cholera, also growths of bacillus 

 of chicken cholera &c. &c. were shown by him. 



The exhibits from the Departments of Agriculture, Public 

 Instruction, Forests and Public Works were highly interesting. 



Several members also contributed to the success of the Conver- 

 sazione by valuable exhibits of Microscopes, Photographs, Works 

 of Art, rare prints &c. A hearty acknowledgement is due to the 

 various exhibitors for the most valuable assistance rendered by 

 them in making this Conversazione not only interesting but highly 

 instructive.
