In 1711, around the time Sherard finished composing his second set of sonatas, the Duke died, and Sherard's interest in music seems to have died with him. He also fell ill with
gout, which prevented him from playing the violin. Instead, he turned to botany; he wrote in August 1716 that "of late the love of Botany has so far prevailed as to divert my mind from things I formerly thought more material". According to
Blanche Henrey it was "the most important book to be published in England during the eighteenth century on the plants growing in a private garden" and a major work for the pre-Linnaean taxonomy of South African plants, notably the succulents of the
Cape Province. Dillenius' herbarium specimens from Eltham are preserved in the herbarium of the
Oxford Botanical Garden. ==Later life==
