Scientific Work of Dr. C. H. Turner 15 



his studies be did not venture on lengthy and costly voy- 

 ages to far-away countries teeming with fascinating 

 alhirements. In his scientific work, as in his other inter- 

 ests, he had the ability to take the material that was 

 near at hand and make the most of it. 



Among Dr. Turner's notes were three completed 

 papers of a less technical nature, which will be published 

 by The Academy of Science of St. Louis. The titles are : 

 "Tropisms in Insect Behavior," ''The Homing of the

 they have named a certain type of orientation after this 

 discoverer. This is best described in Bouvier's book, 

 The Psychic Life of Insects, translated from the French 

 by Dr. L. 0. Howard, where it is "called Turner's 

 circling, using the name of the learned American who

 devotion to various sociological works among his people. 

 Among his unfinished papers were found several chap- 

 ters of a novel, a number of chapters of a book of nature 

 stories for children, and the manuscript of a book of 

 thirty-two poems. Not alone has science lost one of its 

 most thorough students, but also the colored race has
