Coun’s CLassIFICATION OF THE THALLOPHYTES.—This recent 
attempt at a satisfactory disposition of the Thallophytes deserves 
the careful study of botanists. As will be seen, Cohn still holds 
to the view originally put forth by him in 1872, which discards 
the old groups Algz, Fungi and Lichenes. The present arrange- 
a questionable. The Entomophthore are much more nearly 
ao to the Saprolegniz (if indeed they are not to be classed 
ith them) than to Piptocephalis and Mucor.
