simple as possible by presenting only the most important points, 

 by excellent illustrations and by footnote explanations of all 

 technical terms. The opening chapters on the phylogeny and 

 otogeny of the brain are very readable and the final one, the sum- 

 mary, undertakes to make clear the method of operation of the 

 brain. It, too, is exceptionally lucid. The body of the book 

 deals with the chief anatomical feature of the brain, the location 

 of external land marks, the main regions of the gray matter — both 

 superficial and internal and the fibre-tracts of the interior. It is 

 intended as a laboratory guide, though it will help any student to 

 clearer notions of the brain even if the laboratory work is not done. 



A timely and practical Bulletin on Bee Keeping in Iowa, 

 written by Frank C. Pettet, State Inspector of Apiaries has just 

 been issued, as a help in extension work, by the Iowa State College 

 of Agriculture. It is especially helpful in that it gives statistics 

 based on the experience of ten or more practical apiarists, giving 

 the largest honey record for single colonies for a season, the aver- 

 age yield of an apiary for any good season and ten average annual 

 yields for long periods of years. 



Practical suggestions for beginning bee-keeping are given and 

 directions for the management of apiaries and information about 

 bee diseases and the laws relating to foul brood. The Bulletin is 

 in aU. its twenty pages, sensible, conservative and useful.
