during bis successive residence in Cambridge and Harvard, 

 until July, 1807, when he put himself under the instruction of 

 the celebrated Dr. Waterhouse, and was -with him at the time of 

 the introduction of vaccination for the kine-pock into this coun- 

 try. In July, 1808, he entered upon the practice of the profes- 

 sion in the South Parish of Danvers, where he continued to 

 reside until his decease on the 31st of March, 1853, retaining, 

 through a long life the character of the good Physician and the 

 respect and esteem of the community. 



His early taste for the study of Natural History continued 

 not only with unabated zeal, but seemed rather to increase in 

 vigor and activity even to the last. He was particularly con- 

 versant in the local natural history of this vicinity — the 

 geological formations — the flora — the fauna, particularly that 

 of the reptiles, alike claimed his attention. Several communi- 

 cations from him, on the habits, &c., of the Batrachians, have 

 been printed in the Journal of the Society. In all our excur-

 localities of plants, &c., rendered him a very acceptable and 

 pleasant guide and instructor ; — to him we owe much, and to 

 his suggestions we are greatly indebted for the success of these 

 gatherings. 



In the various movements of society, for the amelioration of 

 the condition of man, he took a deep interest, and was always 

 ready to contribute in aid of the same. We also find him, a 

 pioneer with Pickering and others, in the organization of our 

 County Agricultural Society, for many years its Treasurer, 

 one of the Trustees, and the orator at the Cattle Show in 

 Topsfield, on the 5th of October, 1820. In the Massachusetts 

 Medical Society he was an active member, for many years 

 a counsellor and the President of the Society for this district ; 

 he delivered the annual address in 1837, which was printed in 

 their communications — subject, "Irritation of the Nerves." 

 On other occasions, he manifested the same zeal and ready co- 

 operation ; and several addresses by him have been printed, which 

 remain as memorials of his study and research in the fields of 

 science and literature ; — among these may be mentioned, a 

 Masonic Address, at Danvers, in 1811 ; a Discourse on " Tern-
