316 BIOGRAPHICAL SKETCHES. 



nated in the White Mountains — then to be reached only by 

 a laborious journey of two days on foot — were Francis C. 

 Gray, Judge Shaw, Nathaniel Tucker, and Dr. Jacob Bige- 

 low, the Nestor of New England botany, now the sole surviv- 

 ing member of the party. An interesting account of the as- 

 cent of Mount Washington, written by Dr. Bigelow, was pub- 

 lished at the time in the fifth volume of the " New England 

 Journal of Medicine and Surgery.' ' 



In the year 1820 Dr. Boott crossed the Atlantic for the 

 last time, and proceeding to London entered upon the study 

 of medicine, under the direction of the late Dr. Armstrong. 

 He continued his medical studies at the University of Edin- 

 burgh, where he took the degree of M. D. in 1824. The next 

 year he established himself in London, we believe in the very 

 house in Gower Street where he resided until the day of his 

 death. He was soon associated with his near friend and former 

 teacher in the work of instruction, becoming Lecturer on Bot- 

 any in the Webb Street School of Medicine, where Dr. Arm- 

 strong was Professor of Materia Medica. 



"His lectures are said to have been admirable, both in 

 matter and style, and to have excited much enthusiasm ; 

 whilst his untiring efforts to promote the welfare of his pupils 

 in other ways were so deeply and generally felt, that, on the 

 eve of his too early withdrawal from the lectureship, they in 

 one day raised a large subscription to present to their friend 

 and teacher ; — a tribute which, with the characteristic 

 modesty and consideration, was declined as soon as heard of. 

 He was, however, afterwards persuaded to accept a collection 

 of books instead, in remembrance of their grateful feelings 

 and good will." 



The early death of Dr. Armstrong, cutting short a distin- 

 guished career, imposed upon his friend the duties of a biog- 

 rapher and expositor. Accordingly, after much preparation, 

 Dr. Boott, in the year 1834, published two octavo volumes, 

 entitled, " Memoir of the Life and Medical Opinions of 

 John Armstrong, M. D. ; to which is added an Inquiry into 

 the facts connected with those forms of Fever attributed to 

 Malaria and Marsh Effluvium." He published, besides, in
