Flecker's School Chemistry puts beginnern' chemistry upon a strictly experimental basis, since directions for performing 112 experiments comtitute t h e greater part of t h e work. The author has seen fit to include s direursion of rertain law. and theories. There are sandwiched in between t h e directions for performing the erpYimentr. A teacher who desires to make the papil's laboratory work the Doint of deoarture of his course and who ~ipproverof a book with rather more in the way of thought~direefingsuggestions than may be found in the usual laboratory manual will probably find thin book to his liking. The content of the courae described is not strikingly different f m m t h a t which may be found in any good American text, and the author acknowledges hip indebtedness to one of our brst known American textbook writers, now deceased, whose hooks are noted for their rigorous development of chemical theory. This book is printed upon a good quality of unglazed paper and the illustrations are nll line d r a w i n s of such a character t h a t they can be copied by the pupils into their reports. S.
