362 WILLIA3I SWEETSEE. 



Legion of Honor, in which order he was subsequently raised to the 

 rank of officer. He was a Fellow of the Royal Society of London, of 

 the Imperial Leoj^oldo-Caroliuian Academy of Germany, and of many 

 other scientific societies. In the year 1857, he was president of the 

 American Association for the Advancement of Science. 



In 1869, his advancing years and failing health, together with the 

 necessity of devoting more time to his large estate, led him to resign 

 his position as director of the geological survey, though he still con- 

 tinued to spend a portion of his summer in geological exploration, 

 much of which was in the western parts of Vermont and Massachu- 

 setts. The incompleted results of these last few years, however, 

 remain unpublished. He left his home in Montreal in August, 1874, 

 to spend the autumn and winter in Great Britain, intending to re- 

 turn to his geological labors in the spring ; but, his bodily ailments 

 increasing, he died and was buried at the home of his sister in Wales. 



Sir William Logan was unmarried, and, though genial and kindly in 

 his social relations, led a solitary and very retired life. His work in 

 science was neither that of a paleontologist, a lithologist, or a miner- 

 alogist ; in all of which departments he was, throughout his career, 

 ably seconded by the labors of James Hall, Sterry Hunt, Dawson, and 

 Billings. His great merit was the possession of a rare skill in strati- 

 graphy, and an amount of patience, industry, and devotion to his work, 

 which has rarely been equalled, and has enabled him to connect his 

 name imperishably with the geology of the older rocks. 



WILLIAM SWEETSER. 



William Sweetser, sou of William and Elizabeth (Bennison) 

 Sweetser, was born in Boston, September 8, 1797. He was fitted for 

 college under the tuition of Rev. Mr. Frothingham, then of Saugus, 

 afterward of Belfast, Me. He entered Harvard College in 1811, 

 was graduated in 1815, and received his medical degree in 1818. He 

 then settled at Sherburne, Mass., where he came at once into an 

 extensive country practice, and won the entire confidence and high 

 regard of the community. 



He received the Boylston prize in 1820, for a dissertation on 

 " Cynanche Trachealis, or Croup;" and again, in 1823, for one on 

 "The Functions of the Extreme Capillary Vessels in Health and 

 Disease." He subsequently, in 1829, received a premium offered by 

 the Massachusetts Medical Society, for the best dissertation on " In- 

 temperance."
