Dr. Waterhouse, settling in that part of Danvers, now 

 Peabody, in 1808, where he practised successfully, remain- 

 ing there until his death, March 31, 1853. 



He was particularly interested in the local natural his- 

 tory of this region, and in 1816 delivered a series of 

 lectures on botany, the first of such in this part of the 

 country. Dr. Nichols was one of the founders of the 

 Essex County Natural History Society and its president, 

 retaining unabated till death his interest in his favorite

 extensively in Essex County, Mass., Vermont, the White 

 Mountain region, and southeastern and western Massa-

 Thompson's history of that state ; and his work at the 

 White Mountains was so thorough that recent collectors, 

 with all the advantages of improved roads and easy access 

 to every portion of that region, have failed to add but few 

 to the number of species which he discovered there. It was 

 his intention to have published a flora of New England, 

 but was deterred by the appearance of Beck's Botany. 

 He afterwards became deeply interested in a work, with 

 illustrations by Sprague, upon White Mountain scenery, 

 which was published in 1848 ; but not until after his death 

 which occurred July 31, 1848, the preface of the work 

 having been written July 26, only five days previous. 



Mr. Oakes was impulsive and generous ; thoroughly in
