twice their former size. By the
addition of weak [?] by [?]
the second coat was removed
leaving the granular contents as [?]
that seemed to have a thin coat
holding them in place.
One of the brightest of the
Juniors in class this May gave
[us?/as?] a distinction between Gymnospores
& Angiosperms that the pollen grains
of the former are more than [unicellular?].
Our recent observations would settle that
though of course we did not consider the
ground taken a [?] [on?/one?].
Another and perhaps as interesting
point was the fact that there were
two distinct kinds of pollen grains
and the Juniper. There is the kind
above mentioned and a second somewhat
smaller the contents of which [?]
of being quite homogenous were rolled
up in small balls like spoers in a
[sporangium?]. The coats of these did
not separate neither did they swell
up as did the others by the use of
water or [?]. There were about
[five?] percent of this form. I had two
of the sudents draw the grains. Normal grain at
a (both cards) – one coat [?] to b. – coats c. c –
granul[ar?] contents d. – second coat [?] e – abnormal
grains f.f. –
