PRDi'". IJLLLERS original vohinie. entitled 

 " Researches on Funui," was puhlislu-d in 1909, 

 and with its distim-tix'e ])oint of \ie\\' and original 

 observations attracted eousidcrahle attentioii amonir 

 botanists. The author, in the prefaet to tin juoeni 

 volume, stales that it is to be considered as \olume 2 

 of the ori-inal work, and that volumes 3 and 4 are in 

 an ariixe >tate of preparation. Such industry is itself 

 remarkable, but such prodiu ti\ity in book pul)liea- 

 tion is even more so at the present time, and is 

 explained by the generous help towards publication pro- 

 vided by the Canadian National Council for Scientific 

 and Industrial Research. The Riiniinuhain Natural 

 History ai\d rhilosoj)hical Society has made a grant 

 towards the cost of reproduction of the illustrations 

 in the present volume, which include many beautiful 

 photographs as well as a number of the author's 

 original and extremely helpful diagrams. 



The volume divides sharply into two sections. The
