 the study, laboratory, or observatory." — Nature, 



" A very excellent and thoroughly up-to-date annual." — English Mechanic. 



"The additions and improvements made in the current issue of this well-known scientific diary make 

 it, if possible, even more indispensable than ever to naturalists and scientific men." — The Naturalist. 



" The whole production is unique, and its general get-up is beyond praise." — Electrical Review-. 



"Of the stream of year-books .... very few — if indeed any — can surpass in point of use- 

 fulness and excellence of appearance the volume before us." — The Electrical Engineer.
