SCIENTIFIC BOOKS 

 Tierhau und Tierlehen. Von R. Hesse und 

 P. DoFLEiN. Band 2. Das Tier als Glied

Teubner, Leipzig tmd Berlin. 8vo. Pp. xv 

 + 960. Y40 text illustrations and 20 plates. 

 The second volume of Hesse and Doflein's 

 " Tierbau und Tierleben " has just been issued 

 by Teubner, of Berlin and Leipzig. The first 

 volume, from the pen of Professor Hesse, ap- 

 peared in 1910 and dealt with the structure 

 and functions of the animal body. The com- 

 panion volume, the work of Professor Doflein, 

 bears the date of 1914 and takes up the con- 

 sideration of the animal as an element in 

 nature. It is divided into three books. The 

 first has to do with animals in their relations 

 to their organic surroundings and deals with 

 their feeding habits, their means of defense, 

 their sexual life, their migrations, the care of 

 their young, and their social life. The second 

 book treats of animals in their relations to their 

 inorganic environment, such as general cosmic 

 changes, the surrounding medium and the sub- 

 strate, the quantity and quality of food, tem- 

 perature and climate, and light. The third 

 and last book has to do with the adaptive struc- 

 tures and activities of animals, and the ex- 

 planation of these phenomena. The volume 

 contains almost a thousand pages and is illus- 

 trated by some twenty plates and over seven 

 hundred text-figures. The press work, includ- 

 ing the illustrations, is beautifully done. 

 Gothic type, however, gives the page a less mod- 

 ern scientific aspect than Roman would have 

 done. Some of the illustrations, like Pig. 574 

 of the sleeping places of Indian birds, verge 

 more on the theatrical than on the natural; 

 others, like Liljefors' grouse and wild-goose 

 plates, are really wonderful works of art. 

 Here and there a few mistakes are to be noted; 

 thus Fig. Y21 is incorrectly attributed to 

 Packard. But in such a wealth of material it 

 is impossible to comment critically. Suffice it 

 to say that the immense body of new and accu- 

 rate information brought together in this vol- 

 tune will make it a most welcome addition to 

 the present source of information used by the 

 modern zoological reader. G. H. Parker
