tion: The State University, Leiden. Note: Alphonse Lavallée 
states that “the first greenhouse’ was established at Leiden in 
1599, “for the protection of some plants introduced from the 
Cape of Good Hope, Geraniums, Mesembryanthemums, ete. It 
contained, according to Boerhave, nearly 6000 plants.” 
Sir William Brereton (Travels in Holland, London, 1844) 
states that this Garden is one of only two things “memorable ” 
about the University of Leiden. He describes how Adolphe Van 
Voorst gave his lectures in this Garden “ very fluently ” in Latin. 
“ His manner is to take a whole bed, four yards long and one 
broad, and to discourse of the nature and quality of every herb 
and plant growing therein, which he points out with his staff when 
” 
he begins to speak thereof.
