meeting having been confirmed, the Hon. Secretary read a letter he had received 
from Mr. C. P. Hobkirk, author of the ‘‘Synopis of British Mosses,” in 
reference to the Society’s reports on the ‘‘ Naturalist ;” and also on the advisa-

knowledge of the anatomy and the development of Cryptogamic plants
