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 surviy- 
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
