of Edinburgh , Session 1866-67. 
Emperor of Russia, and from the Kings of Prussia and Holland, 
as acknowledged merits as a lighthouse engineer. When his 
health prevented him from attending the meetings of this Society, 
he gave in his resignation, but the Council declined to accept it, 
and continued to him all the privileges of a Fellow. 
The long illness of Mr Stevenson, produced no doubt by the 
severity of his exposures at Skerryvore, and the responsibilities and 
anxieties attaching to so great and difficult a work, was borne with 
exemplary patience and resignation, and he died at Portobello, as a 
Christian should die, on the 23d December 1865, in the 58th year of 
his age. 
Robert Kaye Greville, a distinguished botanist, was born at 
Bishop Auckland, on the 13th December 1794, and was the son of 
the Rev. Robert Greville, Rector of Wyaston in Derbyshire. While 
he was receiving his education under his father’s roof, he spent his 
leisure hours in the study of plants ; and so rapid was his progress, 
that before he was nineteen he had made careful coloured drawings 
of between one and two hundred native plants. Being intended for 
the medical profession, he went through the usual curriculum of 
four years in London and Edinburgh ; but circumstances having 
rendered him independent, he resolved to devote himself to his 
favourite study. 
In 1816 he married a daughter of Sir John Eden, Bart, of Win- 
dleston, and in the same year he came to Edinburgh, w r h ere he studied 
human and comparative anatomy under Dr Barclay. 
In 1816 he joined the Wernerian Society, to which he communi- 
cated a series of papers on Algse, which are published in the Trans- 
actions of the Society. In 1823 he published the first volume of 
his great work, entitled “ Scottish Cryptogamic Flora,” which he 
completed in six volumes, in 1828. His “ Flora Edinensis,” con- 
taining a description of the plants in the neighbourhood of Edin- 
burgh, appeared in 1828 ; and in 1830 his u Algse Britannicse,” a 
description of the marine and other inarticulated plants in the 
British Islands, belonging to the Order Algse. In conjunction with 
Dr Hooker he published the “ leones Filicum,” a splendid work, 
containing drawings and descriptions of ferns, either very rare or 
which had been incorrectly figured.
