The principal Body of each Kernel, confifts of a hard, callous or 
carrilagc-like, uniform Subftance, made up of two Lamin^^ firfl 
laid one upon the other, and then rowled and folded up into the 
figure wc have juft now deferibed. 
Whoever views a tranfverfc feflion of a Kernel, the firft Idea of 
its Strudure that willprefent its fclf, is undoubtedly that of a Body 
rowled up, as I have faid j but I think a more eafy way to conceive 
that fully, will be firft to imagine two oblong hollow Hemirphe- 
roids cafed clofcly over one an other, and covered with a Lid flit- 
ted through the Middle lenthwifej and then, that this Cavity is 
filled up by another Body adhering to, or proceeding from the whole^ 
under part of one fide of the Lid, but loofc from the other, under 
which the Ege of it is turned up, fo as to form a new kind of Sul- 
cus continuous with the former, tho" not always in the fame fight 
Line. 
This inner Body I know no better way to exprefs, than by cal» 
ling it a Procefs, arifing from one fide of the Slit or Sulcus fo often 
mentioned. 
The ftruflurc of a Angle Kernel is to be conceived much after 
the fame manner, only here the Slit is generally wider, the two 
fides of it being not flat but convex, and fo appear rather as a con- 
tinuation of the fame Figure with that of the back-fldc of the Ker- 
nel, than as a Lid laid over a Cavity. By this means likewife the 
figure of the Cavity varies, and that of the Procefs along with it. 
In every thing clfe the ftrudurc of both kinds of Kernels is the 
fame. 
About both the one and the other, there arc thefc two Things 
further to be obferved : Firft, that the two Lamin£y of which they 
arc compofed, are not every where of equal Thicknefs, from whence 
it follows, that one fide of the Cavity is fometimes more lhallow 
than the other. 
In the next Place j the Procefs docs not always come out from 
the fame fide of the Sulcus, or which is the fame Thing, the Ker- 
nel is not always rowled up one way j by which I mean, that the 
fituation of all the parts of the Kernel, being determined by that of 
the feminal Plant, of which, in the next Article j the Procefs ad- 
heres fometimes to the right fide of the Sulcus, and fometimes to 
the left. Ranwolfus
