the London Exhibition of 1851 as recipient of one of their Science 
Scholarships. This scholarship, of the annual value of one hundred 
and fifty pounds sterling, is tenable for two years on the condition that, 
during his tenure, the holder shall devote himself wholly to study and 
research, more especially in some branch of science, such as_ physics 
mechanics or chemistry, the extension of which is especially important 
to our national industries. The Senate’s nomination to the Royal Com- 
missioners was accompanied by a copy of Mr. McKittrick’s paper from 
the Institute’s Transactions to show the author’s capacity for research 
work. 
Mr. D. M. Bliss, electrician, Amherst, in a paper titled, ‘‘ The coming 
? 
development of artificial illumination,” set forth a number of interesting 
facts and problems that are now engaging the attention of electrical 
engineers, and that are not only of scientific interest, but also prospec- 
tively of economic importance to civilized communities. 
Mr. John Forbes, whose mechanical inventions in connection with 
iron manufactures have brought fame to our city, presented us with a 
review of some modern methods in manufacturing, with suggested analo- 
cies from a study of the evolution and nature of some of the processes 
employed. The reading of this paper led to an interesting discussion on 
the processes of manufacture of the different kinds and qualities of iron 
and steel, the observations of the speakers being well illustrated by a 
series of samples exhibited by Mr. Forbes, which showed the several 
progressive steps In the processes of manufacture. . 
Our April meeting was held in the Church of England Institute 
building ; the attendance was unusually large, both of ladies and gentle- 
men, notwithstanding the disagreeable weather. The evening was 
entirely devoted toa paper by Dr. D. A. Campbell, titled, ‘‘ General 
considerations concerning Bacteria, with notes on the bacteriological 
analysis of water.” Dr. Campbell had studied Bacteriology at Johns 
Hopkins University, where unusually ample facilities are offered, and he 
has continued the investigation since his return to Halifax. In this 
paper he gave a clear exposition of the most important results of bacterio- 
logical enquiry up to the present time. He described the principal 
forms of bacteria, with respect to their characteristic features in form and 
size, the changes which they undergo, the parts they play in the economy 
of nature, as in putrefactive processes, in converting organic substances
