‘‘Théorie Elémentaire.’ In 1855 appeared his ‘ Géographie 
botanique raisonnée,” published in two volumes, and containing, in 
1,300 pages, ‘‘an exposition of the principal facts and laws concerning 
the geographical distribution of plants at the present day.” ‘In its 
aggregation of facts and results, and in their skilful marshalling,” says 
a reviewer in the current issue of the Gardenev’s Chronicle, ‘* it is com- 
parable only with the works of Darwin, some of whose views were 
indeed something more than foreshadowed by the great Swiss 
botanist.’”” In 1867 he laid before the International Congress of 
Botanists at Paris his ‘‘ Lois de la nomenclature botanique,” which 
still forms the basis of modern botanical nomenclature. In 1880 
appeared ‘‘ La Phytographie,” or the art of describing plants, a work 
of the utmost value to every systematist, and concluding with an 
invaluable list of the principal herbaria. His ‘‘ Histoire des Sciences 
et des Savants depuis deux siécles”’ (1873) is a charming book, and 
quite intelligible to the general reader, while his ‘“‘ Origine des Plantes 
Cultivées,” a translation of which is published in the “ International 
Science Series,” is also well-known. 
These do not represent nearly all of the stately and courteous 
Professor’s contributions to botanical science, but this is but a short 
biographical notice, not a bibliography, and no place can be found for 
his numerous papers dealing with very various aspects of botany. 
De Candolle made several memorable visits to this country. 
When about two-and-twenty he came over to London, and leaving 
the metropolis in May went down to the West of England. 
Thence he worked up through Wales and the English Lakes to 
Glasgow, where he met Sir William Hooker, then Professor of 
Botany at the University. From Glasgow he went to Skye, and 
having done the island on foot, crossed to Inverness, and so back 
to London, where he arrived again in the autumn. Certainly a very 
creditable tour, considering the means of communication more than 
sixty years ago. 
In 1866 he presided over the London Botanical Congress held 
at South Kensington, and in his address emphasised the great im- 
portance of an intimate relation between botany and horticulture. 
In May, 1850, he was elected a foreign member of the Linnean 
Society, of which he was at his death the senior foreign member. 
In 1889 the Society conferred on him its gold medal, the highest 
honour it has to give. The President, when announcing the sad news 
at the meeting on the evening of April 6, mentioned that his son 
Casimir, who has done good botanical work, had been selected by 
the Council for nomination as a foreign member. 
De Candolle loved the English and English ways, dining in 
English fashion and speaking English largely at home, and, in 
common with the rest of his family, was by no means friendly 
disposed to the political powers of his native city. 
He was well and vigorous till within six months of his death,
