In a sTuDy of regermination of seed Mr. A. M. Ten Eyck has found 
(Agric. Science v1, 454) that wheat will germinate fourteen times, after 
an interval each time of seven days drying at ordinary temperature | 
Corn gave six such germinations, radish five, parsnip and carrot two, 
and celery, clover and pansy one. It was also found that the seeds of 
any lot which germinated quickest were strongest and could withstand _ 
more drying. See also this journal, xvit, 230. 
M. JuLes Carpor has begun in the fifth and sixth numbers (double) _ 
of the Revue Bryologique for 1892 a list of all the species of mosses | 
now known from North America, showing their geographical distribt.

& James’ Manual and all new species described since its publication, | 
except in the case of evident duplication. Enumerated in this wa 
(useful at present, but obviously an overestimate) our bryologic flor 
contains about 1350 species. igs
