214 JOHN c - BRANNER 



in 1875 to the day of his death he visited the United States only 

 twice. One of these visits was in 1883 when he spent three 

 months at Washington; the other was in 1890 when he attended 

 the meeting of the American Association for the Advancement of 

 Science at Indianapolis. 



When the Commissao Geologica was abolished in 1877 the rest 

 of us took to our heels. Not so Derby; he was not to be stampeded 

 by a simple lack of funds or of employment; he meant to save the 

 results of the work of Hartt and of his colleagues, and, in so far 

 as it could be done, he did it. 



Personally Derby was one of the kindest-hearted and most 

 affectionate men I have ever known. His last dollar was at the 

 service of his friends, and his right hand knew nothing of the kind 

 deeds done by his left. The beggars in the streets found him their 

 easiest victim. 



He was held in the highest esteem in the community in which 

 he lived. He stood for uprightness and honorable dealing, and he 

 was never the willing tool of designing adventurers. For many 

 years he has been justly regarded as the leading geologist in South 

 America, and his standing is due, not to the fact that there are but 

 few first-class geologists in South America, but to his ability and 

 to his excellent work. 



In 1892 he was awarded the Wollaston prize of the Geological 

 Society of London, while his distinguished services led to his being 

 made one of the associate editors of the Journal of Geology and to 

 his election to membership in various learned societies in different 

 parts of the world. He was a frequent contributor to the American 

 Journal of Science and to this Journal. 



A list of his papers on the geology of Brazil up to 1909 is given 

 in the Bulletin of the Geological Society of America, XX, pp. 36-42. 

 To that list should be added thirteen additional titles of papers 

 that have appeared since its publication.
