ArT. XXXIX.—Characteristics of the North American Flora: 
an Address to the Botanists of the British Association for the 
Advancement of Science at Montreal; read to the Biological 
Section, August 29; by ASA GRay. 
WueEn the British Association, with much painstaking, 
honors and gratifies the cultivators of science on this side of 
the ocean by meeting on American soil, it is but seemly that a 
corresponding member for the third of a century should en- 
deavor to manifest his interest in the occasion and to render 
some service, if he can, to his fellow-naturalists in Section D. 
I would attempt to do so by pointing out, in a general way, 
Some of the characteristic features of the vegetation of the 
country which they have come to visit,—a country of ‘ mag- 
nificent distances,” but of which some vistas may be had b 
those who ean use the facilities which are offered for enjoying 
them. Even to those who cannot command the time for dis- 
tant excursions, and to some who may know little or nothing 
of botany, the sketch which I offer may not be altogether un-
