DR. JOHN LINDLEY. 385 
Cucliog an editor for the ' Collectanea Botanica,' This work was published in 
1821, and is dedicated to Mr. Sabine by its editor, who was even at that time 
able to sign himself a member of the Imperial German L. C. Academy of 
Naturalists. In 1820 Lindley published his * Rosarum Monographia,' which 
was dedicated to Mr. Charles Lyell, of Kinnordy, who was so pleased with tlie 
work that he sent the author a cheque for £100. With this money Lindley 
bought a dissecting microscope and a small herharium. lu 1820 he was again 
at Halesworth, and found some Duckweed in flower; a description of which 
appeared in Hooker's ' Flora Scotica.' In 1821 the Monograph on the genus 
Digitalis was published, illustrated partly by himself, but chiefly by Ferdinand 
Eauer. In this year was brought out a foho volume of Chinese drawings, pre- 
served in Cattley's library. No editor's name is appended, but it seems pro- 
bable from the preface that Lindley arranged these plates for publication. 
In 1822 Lindley became garden-assistant secretary to the Horticultural 
Society, of which Mr. Sabine was then honorary secretary. In 1826 he was 
appointed sole assistant-secretary to the Horticultural Sociefyj having duties 
to perform both in London and at Chiswick. From this time he may be said 
to have become the mainspring of the Society, upon which depended its efficient 
working aa it advanced in prosperity, requiring his daily attendance dui-ing 
office hours in Begent Street, or once a week at the Garden, besides fi^equeut 
extra work in the early^moming. In 1830, at the time of Llr. Sabine's resig- 
nation, the Society had got into difficulties, which taxed his energies and atten- 
tion to the utmost to overcome. In conjunction with Mr.Eentham (honorary 
secretary), he worked out a plan for holding at the Garden general exhibitions 
of flowers and fruit, in lieu of the old expensive fetes, which somewhat restored 
the Society to its former prosperity, and became the model on which similar 
exhibitions were established. On these days Lindley's duties were extremely 
onerous. He was always in the Garden before six o'clock in the morning, and 
he never left it until after six in the evening. Nor -nere the meetings m 
3?egent Street less the object of his care. Before Mr. Bentham's resignation in 
184*1, arrangements were made by which almost the whole business till then 
performed by the honorary secretary should, in addition to his own duties, fall 
upon Dr. Lindley, who took the designation of vice-secretary. In this office 
he contmued until 1858, when he resigned, and became secretary to tlie Society 
and member of council. In addition to the Horticidtural Society, he had his 
lectures both at University College and at the, Botanic Garden of the Society 
of Apothecaries at Chelsea, in which latter establishment he lield the office 
Prsefectus Horti, as well as his own personal researches, to engage him. His 
connection with University College began in the year 1829, and he continued 
to lecture in that institution until 1861, when he resigned. Upon his resigna- 
tion he was made Emeritus Professor, at the instance of Professor De Morgan, 
and was subsequently appointed to the office of Examiner of Botany in the 
University of London from 1861 to 1863. For many years his class was very 
large, but as the number of botanical lecturers (many of whom had been liis 
pupils) increased, it fell off. Dr. Lindley never read a lecture, but he invafiably 
prepared notes, and paid great attention to the arrangement of his matter- His
