objects. In 1887 he issued his first list of purely scien- 
tific lantern slides, which gave an impetus to science 
work in the district, He was one of the founders of the 
Manchester Microscopical Society, and for several years » 
one of its presidents, and a lecturer in its Extension Sec- 
tion. It will, however, be on account of his photographic © 
work that he will be best remembered. It is said that 
he took no less than ten thousand photographs of Geo- 
logical Sections during the construction of the Manchester 
Ship Canal, and also of its chief engineering features. 
To attain such a remarkable pictorial history of that gi- 
gantic undertaking, Mr. Ward used at least once a month | 
to walk along the whole course of the works between 
Manchester and the Mersey above Liverpool during the 
period of construction, which lasted beyond five years. 
C. BAKER’S SLIpDE-LENDING SystEM.—-The system of slide 
lending— initiated, we believe, by Mr. ©. Baker, and since 
adopted by other firms, such as Messrs. Watson & Sons, 
of London, and Mr, Abraham Flatters, of Manchester— © 
was a departure that had much to recommend it. Mr. 
Baker’s system, in brief, is that for a subscription of $5, 
the subscriber becomes the recipient of twelve deliver- 
ies of twenty slides each, post free both ways. These — 
slides can be arranged for delivery at stated times—say, 
fortnightly during the winter months, or the time of re- 
ceipt and return can be left to the varying convenience of. 
the subscriber. The choice of slides is most comprehen- | 
_ sive; in the list before us we note twenty-five sets of di- 
toms alone, and four sets of bacteria, The mere examina- 
tion of slides, however, whether arranged for a definite 
purpose or not, falls far short in interest and in educa- 
tional value of the same slides accompanied by the neces- 
sary descriptions and explanations. Recognizing this, 
Mr. Baker has now arranged that full descriptions shall 
accompany the slides lent, and has given us the opportu- 
nity of perusing several of these sets of detailed notes.
