geographical work of recent Swiss phytogeographers. As for rival 
schemes for the expression of the facts, it is certain that in the end 
the fittest scheme will survive ; but there is, in my opinion, no hope

completed during the life-time of the present generation of ecologists. 
Dr. Rubel’s monograph concludes with a long list of references 
to the literature cited in the work, and with a full index.
