In 1851 he published the " Shells of New England," with notes 

 on their structure, as well as valuable geographical and bathy- 

 metrical data ; in 1854 appeared his " Synopsis of the Marine 

 Invertebra of Grand Manan or the region about the Bay of Fundy, 

 New Brunswick ; " and numerous contributions were made by him 

 to various scientific journals up to the time of his appointment as 

 zoologist to the United States Surveying Expedition of the North 

 Pacific and Japan Seas, under Commanders Ringgold and Kodgers ; 

 (of the results of which expedition a part only has been published, 

 relating principally to Molluscan and Crustacean forms) ; subse- 

 quently his " Review of the Northern Buccinums," Check-list of 

 the Shells of the East Coast of North America from the " Arctic 

 Seas to Georgia," " On the Structural Characters of the so-called 

 Melanians of North America," and " Researches upon the Hydro- 

 biinae and allied Forms," besides other contributions of more or 

 less importance which have appeared from time to time. 



His MSS. relating to the invertebrates of the North Pacific 

 Exploring Expedition, illustrated by numerous drawings, the labor 

 of years, and ready for publication, were all destroyed by the great 

 fire which devastated Chicago, and consumed the building and col- 

 lections of the Academy of Sciences of that city. Of this terrible 

 conflagration and its result to him. Dr. Stimpson wrote, " My own 

 books, collections, MSS. and drawings — twenty years' work — all 

 gone ! " 



His health which for some years had been declining, induced 

 him of late to seek, in winter, the milder climate of Florida ; and it 

 was upon the eve of one of these winter expeditions to that State 

 (in January to March, 1869) that I had the pleasure of joining 

 and afterward working Avith him in the field ; and of learning, by 

 personal contact, his worth and scientific ability, and his modest 

 estimate of himself. 



I shall never forget the delightful season passed in his company, 

 the pleasant toils of each day, and of the rehearsal of each day's 

 triumphs in the evening as we sat in front of the blazing fire of 

 pitch-pine, which lighted up his face with a glow less genial than 

 the smile which played around his lips ; or when some joke more 

 pungent than usual was uttered, the explosion of laughter which fol- 

 lowed, and which was joined in by none more heartily than himself.
