and suggestive review a few details as to the Flora itself. iblio-

“are with the Halifax Naturalist between 1896 and 1904, but 
p. 1-120 were ‘‘revised and reprinted in 1900,’ which practically 
peas the work up to that date. The chapter on ‘ plant distribu- 
tion ‘aud associations,” although doubtless capable of extension, as 
Mr. Woodruffe-Peacock suggests, strikes us as being carefully 
and as an sacanide? upon the treatment of these subjects even in 
recent floras. There is an excellent bibliography: the ‘“ historical

ot unduly drawn out, and are rightly confined to those of local 
worke ers, the principal of whom were James Bolton (fl. 1758-1795),
