plants, which will be made the fubjeel of the 
next lecture. The poppy and tulip ftiow the 
ftigma attached to the germe, without the in- 
tervention of the ftyle ; the germe of poppy 
with it's ftigma is very beautiful ; the ftigma 
fhuts up the germe, like the lid of a box ; 
when the germe is mature, it is of that fpecies 
of feed-veffel called a Capfule, and opens at" 
the top in feveral places to give paffage to 
the feeds, which are very numerous. From 
one head of white poppy 8000 feeds are faid 
to have been produced in one fummer. Th.is 
has been afcertained by counting the number 
of feeds, which would weigh a grain or two, 
and then by weighing the whole. Seeds of 
ajl kinds well repay the trouble of examina- 
tion, when, viewed through a microfcopc, in- 
finite beauty appears in their conftruction, 
which, from the minute fize of many of them,
