perous society, with almost undivided responsibility until 
1858, when, dropping the laboring oar, he became secretary 
and member of the council, and took a leading part in the 
reorganization of the society, until, fairly broken down by 
overwork, in 1862 he was obliged to retire from the manage- 
ment. Besides his work in the Horticultural Society, suffi- 
cient in itself to task any ordinary powers, Dr. Lindley was 
professor of botany in University College from 1829 to 1861, 
giving elaborate courses of lectures every year, and also lec- 
turer at the Apothecaries Garden at Chelsea for nearly the 
same period. He conducted the “ Botanical Register” from 
about 1823 (although his name does not appear upon the 
title-page until somewhat later) down to its close in 1847; 
he did the principal botanical work in Loudon’s “ Encyelo- 
pedia of Plants,” and wrote the botanical articles for the 
“Penny Cyclopedia,” down to the letter R; contributed to 
the Transactions and Proceedings of the Horticultural Society, 
and edited its Journal; prepared the later volumes of Sib- 
thorp’s magnificent “ Flora Greea,” etc., ete.; besides writing 
and often reéditing his numerous classical botanical works, 
which, with his lectures to successive classes of pupils inspired 
by his own ardor, have made his name so famous wherever 
botany is cultivated. Of these numerous works we can men- 
tion only the principal. His “Synopsis of the British Flora” — 
arranged according to the Natural Orders, first issued in 1829, 
has only a local and historical interest, as a part of his suc- 
cessful endeavors to introduce and popularize the natural 
system in England, where it had peculiar obstacles to contend 
against. His ‘“‘ Genera and Species of Orchidaceous Plants,” 
with his “Sertum Orchidaceum,” and, later, his “ Folia 
Orchidacea” (which he was able only to commence), embody 
a portion of his labors upon an important and curious family 
of plants, upon which he became the paramount authority. 
His “ Introduction to Botany,” which ran through four edi- 
tions, his outlines of the “ First Principles of Botany,” at 
length expanded into his “ Elements of Botany,” and his 
“School Botany,” form a series of introductory works which 
have done much more for botanical instruction than any others
