For re initiative of this important work we must look back to 
_ year 1848, when Sullivant published in Gray’s ‘ Manual 
of Botany,’ brief descriptions of the Mosses of the northern United 
States,—only 205 in number, but exactly doubled in the second 
edition of the same in 1856. But the ample means and unceasing 
energy of eee could not rest here, and he next gave to the 
world the two magnificent volumes of ‘Icones,’ with which his 
name will lire ver be associate d 
in, and it became dislikes ore su en a more complete guide 
to American Bryology. This Sullivant undertook, ably supported 
by the veteran Lesquerenx, of Columbus, and T. P. James, 
of Cambridge, with the result before us, @ beautifully printed 
volume with descriptions of some 900 species, which no doubt 
be largely exceeded, as the more distant parts of the continent are 
more thoroughly scrutinized. 
During its progress, Sullivant, James and Austin have been 
called away from their e arthly labou urs, er tu 2 has 
27 species are carefully diced: pa beiay new, S. Garberi, allied 
to S. molle, and 8, Fitzgeraldi, close to S. didi biies » after which come 
Andreaacee, represented only by our three commoner British species.
