72 THE NAUTILUS. 



on various branches of horticulture and gardening to the California 

 periodicals devoted to this subject. He was an enthusiastic supporter 

 of the California Academy of Sciences in its early days, and after 

 the earthquake of 1S68, when disaster threatened the Society, he, 

 with Professor J. D. Whitney and a few other friends, stood between 

 it and dissolution. He was a member of numerous scientific societies 

 at home and abroad, and of the Sons of the Revolution. 



Dr. Stearns was a man of sanguine temperament, with a lively 

 sense of humor and high moral character. His reading was wide, 

 his learning never obtrusive, his interest in art, literature and all 

 good causes intense. He was a staunch friend and, for a righteous 

 object, ever ready to sacrifice his own material interests. His ser- 

 vices to Californian science will keep his memory green.

LUDWIG RUDOLPH SOPHUS BERGH. 



Dr. Bergh was born in Copenhagen, October 15, 1824, and died 

 in the same city July 20, 1909. Dr. Bergh for many years stood at 

 the head of the small group of malacological anatomists, devoting 

 himself especially to the Opisthobranchiata and particularly to the 

 Nudibranchiata. His published works on these animals form a small 

 library and a mine of detailed information. The chief results of this 

 unremitting labor are summed up in a large quarto in which he 

 gives a complete systematic arrangement for these animals. Besides 

 this contribution to the knowledge of molluscan anatomy he published 

 several valuable memoirs on other groups of mollusks, an especially 

 notable instance being a fine memoir on the anatomy of the genus 

 Co7ius. He was largely concerned with the publication of the great 

 posthumous series of quartos detailing the results of the researches 

 in eastern seas by Carl Semper, who was his intimate friend. In 

 medicine also his publications, based on the treatment of thousands 

 of hospital patients, took a high rank. 



Personally, Dr. Bergh was most genial and agreeable in manner, 

 ever ready to help younger students, or serve as cicerone to foreign 

 colleagues visiting his beloved Copenhagen. Hospitable and un- 

 pretentious, a staunch friend and untiring student, his death leaves 

 a gap in the ranks of the veterans which we may iiardly hope to see 

 filled, and a memory which those who knew him will cherish long.
