what unceasing delight lias been afforded by this grand sériai, 

 and will continue to be afforded! The almost unparaleled literary 

 activity of him, for whom \ve now are mourning, gave further vent 

 to multifarious other productions for the enrichment of science. 

 Thus as early as 1835 he issued his two large volumes, « Intro- 

 duction à l'Etude delà Botanique, » for teaching purposes. Various 

 publications followed, irrespective of the vast and telling contri- 

 butions to the « Prodromus. — In 1855 apperaed his mémorable 

 and large work on the geography of plants, involving ample con- 

 sidérations of achievements in sciences collatéral to abstract phy- 

 tology; in this book for the first time and mainly from Melbourne- 

 malerial the Flora of Central Australia came under comparative 

 considération and connected review. In 1867 Alphonse de Can-

 through his « Lois de la Nomenclature botanique, » then adopted 

 by the International Botanic Congress in Paris. In 1880 came out 

 a spécial volume on sound rules, how plants professionally ought

 languages; this book again is the resuit of that extraordinary metho- 

 dicity, evinced in ail his extensive writings, and acquired as a 

 heirloom from Augustin Pyramus deCandolle; it élucidâtes with 

 infinité patience and rare grasp of mind a number of questions, 

 bearing on this abtruse and complicate rural subject, much buried 

 in far past history and often only to be unravelled from distorted 

 traditions and other unreliable records prevïously accepted. But 

 Alphonse de Gandolle's attention was not limited to what his spé- 

 cial callings demanded from him; because his history of the 

 sciences of thelast two centuries (1872), therefore of the progress 

 of nearly the whole of newer knowledge through the world, bears 

 winess of the wondrous range of his perceptions and inquiries. 

 With filial piety he devoted the latest of his volumes to réminis- 

 cences of Augustin Pyramus de Candolle. What could be more fas-
