THE QUARTERLY REVIEW OF BIOLOGY 



four parts. In Part I, some fossil birds 

 are discussed; in Part II, the embryonic 

 stages of birds and reptiles are compared; 

 in Part III, some anatomical and biolog- 

 ical features of both classes are given; in 

 Part IV, an attempt is made to find the 

 ancestor of birds and its relations. The 

 book is written in an interesting style and 

 is well illustrated, though just how 

 Professor Heilmann arrived at the color 

 of Archaeopteryx and Hesperornis is not 

 revealed.

 into three parts. The first and largest 

 consists of a series of 19 lectures on 

 parasitic protozoa. The second part in- 

 cludes ten chapters on laboratory methods 

 in medical protozoology. Finally there 

 is a bibliography covering 92. pages, and a 

 detailed index. The book is extensively 

 and fairly well illustrated, and altogether 

 constitutes a valuable contribution to 

 the textbook literature in its field. 



TIGERS, GOLD, AND WITCH-DOC- 

 TORS. 



By Basse tt Digby . Hat -court, Brace and Co . 

 $3.00 5I x 8|; 341 New York 



An entertaining volume of travels and 

 experiences in Siberia, written by a 

 journalist who has been pretty well all 

 over the world. The book is full of 



interest, both to the naturalist and to the 

 human biologist. What the author says 

 about Lake Baikal will set the zoologist 

 crazy to go there. 



CLEARED FOR STRANGE PORTS. 

 By Mrs. Theodore Roosevelt, Sr., Mrs. Kermit 

 Roosevelt, Richard Derby and Kermit Roosevelt. 

 Charles Scribner's Sons 

 $3.00 5! x 8f ; xi + Z54 New York 



As its title would indicate this book 

 written by four members of the Roosevelt 

 family tells of travels and adventures in 

 many lands. There is, in connection with 

 the accounts of hunting trips, a certain 

 amount of information as to habits and 

 behavior of big game, notably elephants 

 and tigers. But somehow these writings 

 lack the touch which our experts in natural 

 history associated with the Roosevelt 

 name. T. R. was a significant, if not a 

 great, naturalist.
