Scientific Work of Dr. C. H. Turner 15 



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

 ages to far-away countries teeming with fascinating 

 allurements. 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 :

 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 

 best studied this phenomenon."

 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
