xxu A Short Explanation 
JS f The upper parts of the oviducts of an un- 
impregnated Bee, in which they are here- 
abouts very flender, contain but very minute 
eggs, but which bend in the fame manner 
mentioned in the preceding article. 
gg The eggs of the ovary of an impregnated 
Bee, which are fenfibly bigger and bigger, 
the nearer they approach the common ovi- 
duct of the fide, to which they belong. 
bbb The eggs of an impregnated Bee, which 
are in every oviduct almoft of the fame fize, 
at the fame diftance from the common ovi- 
duct. 
227 The eggs in the extremities of the ovi- 
ducts of an unimpregnated Bee’s ovary. 
Thefe eggs are not only very {mall in them- 
felves, but {maller, paler, thorter, and more 
delicate than thofe in the extremities of the 
impregnated Bee’s ovary. 
kRkkkkk The eggs in both parts of the ova- 
ty, ready to fall into the greater common 
duct. 
7/1] Theeggs of an unimpregnated Bee, dif- 
fering in fize, but very irrregulary, fome of 
thofe furtheft from the common duét being 
bigger than the others that are much nearer, 
contrary to what appears in the impregnated 
Bee, as has been already obferved under the 
letters g g bd. 
mm The eggs in the extremity of an impreg- 
nated Bee’s ovary, which are bigger, and of 
an oblong, and more regular form. 
%n Two common duéts, or, as it were, the 
horns of the uterus, in which all the parti- 
cular oviducts terminate, and pour their 
eggs.

an impregnated Bee, though one of them 
fupports the ovary of an unimpregnated 
one. :

t A globular or little round part or organ, con- 
taining a glutinous matter, with which the 
eggs are fmeared over before the Bee lays 
them. The interior coat of this bag is curi-

air-tubes.

us, or excretory duc of the eggs, and ferves 
perhaps to fecrete the glutinous matter juft 
now taken notice of, and to convey it to the 
bag deftined to receive it.

ciently examined.
