318 BIOGRAPHICAL SKETCHES.

As it had always been the greatest pleasure, we might say the 
business of his life to assist others, so now friends and corre- 
spondents from all parts of the world hastened to place in 
his hands the fullest sets of their collections in this difficult 
genus; and he was able to study, in the unrivaled caricologi- 
eal collection he thus formed, and the various public and pri- 
vate herbaria to which he had access, almost all of the six 
hundred or more species which the genus was computed by 
him to comprise, to compare them in numerous specimens of 
their various forms, and to examine them, group after group, 
with untiring and closest scrutiny. At length, early in the 
year 1858, he gave to the world (literally gave to the world) 
the first volume of his great work, entitled “ Illustrations of 
the Genus Carex,” a folio volume with two hundred plates, 
admirably representing about that number of species. A very 
large proportion of them were North American species, in 
which he naturally always took a special interest. In the 
letter of dedication of this work to his friend, John Amory 
Lowell, Esq., of Boston, Dr. Boott states that his original 
design “ was limited to the Carices of North America,” but 
that the large collections brought by Dr. Hooker from the 
East Indies, and placed in his hands for study, caused him to 
extend his plan, and to endeavor to illustrate the genus at 
large. With characteristic modesty he makes no allusion to 
the years of labor and the large amount of money (savings 
from a moderate income by a simple mode of life) which the 
volume had cost him; the drawings, engravings, and letter- 
press having been produced at his sole individual expense, 
and the larger part of the copies freely given away. Nor did 
he put forth any promise to continue the work. But in 1860 
Part Second quietly appeared, without a word of preface. 
This contains 110 plates. Two years after, this was followed 
by Part Third, with 100 plates, making 410 in all; and it is 
understood that the materials of a fourth volume are left in 
such forwardness that they may perhaps be published by his 
surviving family. 
Our own estimate of this work has been recorded in the 
pages of this Journal, as the successive volumes were received.
