SCIENTIFIC BOOKS 



In Wildest Africa. By C. G. Schillings. 

 Translated by Frederic Whyte. With over 

 300 photographic studies direct from the 

 author's negatives, taken by day and night, 

 and other illustrations. Pp. xvi + "^lO. 

 New York and London, Harper & Brothers. 

 1907. 



It is safe to say that all who read Herr 

 Schillings's first book on the African wilder- 

 ness, called " With Flashlight and Rifle," or 

 in its American edition " Flashlights in the 

 Jungle," hoped to see more of his " nature 

 documents," and to hear more of his unique 

 experiences on the great velt of German East 

 Africa. It is also safe to say that they will 

 not be disappointed in the attractive volume 

 " In Wildest Africa," which has recently ap- 

 peared. In this work the author has added 

 many side lights as well as " flashlights " to 

 ,his theme — the vanishing fauna of the Dark 

 Continent. 



Herr Schillings's first volume, which I re- 

 viewed at some length in these columns,* was 

 ^Science, Vol. XXIIL, April 6, 1906.
