La Vie et les Ecrits de Sir William Hooker. Par M. Alphonse de Can- 
dolle. (‘Archives des Sciences de la Bibliothèque Universelle,” 
January, 1866.) 
This is a just tribute to the memory of the late Sir Willlam Hooker. 
As we have already given in our pagesa short memoir of that distin- 
guished botanist, and a list of his various works, we draw the atten- 
tion of our readers to this paper, because of an interesting classification 
of botanists which the author gives when forming an estimate of 
the place which the subject of his memoir should occupy. As the 
author alone or in part of six or seven volumes in folio, four in quarto, 
and eighty-seven in octavo, he considers Sir W. Hooker as an example 
of his class of active botanists. We make the following extract, in 
which he explains his classification :—

terized by particular emis and Len se defects. The one class I shall call
