DR. MARTIN BARRY ON THE CORPUSCLES OF THE BLOOD. 
seemed at other times on one side ((3), and at others as though divided 
into several parts (y). Taken from fluid collected on the fimbriated 
portion of the Fallopian tube, in a Rabbit killed 5^ hours post coitum 
(par. 12 to 17 -)- 
Fig. 6. Blood-corpuscles from the Fallopian tube of a Rabbit killed twelve hours 
post coitum. Many of them (a) flat, and in a condition little changed ; 
others (/3) become orange-shaped cells, a portion of their interior pellucid. 
In some (y) the pellucid portion was seen to be, not central but, on one 
side. Certain of them (}) had become elliptical. Some (g) presented 
very minute adherent granules or globules (pars. 20. 21. 33.). 
Fig. 7- Blood-corpuscles — now true cells — from the Fallopian tube of a Rabbit 
killed fourteen hours post coitum. Some of them (£) resembled & in 
fig. 6. Others had considerably enlarged, and sent out processes or arms. 
Such as these enter into the formation of the chorion. When viewed 
singly, the objects in this figure — with the exception of the pellucid por- 
tion which each presents — appeared yellowish ; an accumulation of such 
objects is blood-red (pars. 21. 24. 25. 33.). 
Fig. 8. Outline of part of an ovum of twelve hours, and measuring yj", from the 
Fallopian tube. The cells of the tunica granulosa (g 1 ) — also for the 
most part in outline — had become club-shaped, and were in contact with 
the membrane f by their pointed extremities alone. The object of this 
figure is to show some of the very earliest traces of the formation of the 
chorion. Blood-corpuscles ( clio .), having found their way between the 
cells g 1 , apply themselves to the membrane f, and undergo the changes 
elsewhere described. Three of these corpuscles had passed into the state 
of cells, the contained pellucid object being at the surface ; and two of 
these cells had begun to send out processes or arms (par. 25.). e. Proper 
membrane of the substance surrounding the germinal vesicle. Between 
this membrane and the membrane f there was a space, filled with trans- 
parent fluid.

tube of a Rabbit killed in the state of heat. 
Fig. 10. Altered and now spheroidal blood-corpuscles in fluid collected in the in- 
fundibulum of the Fallopian tube, in a Rabbit killed four hours post 
coitum (par. 49.).

the Fallopian tube, in a Rabbit killed in the state of heat (par. 49.). 
Fig. 12. Epithelium-cells, found with the blood-corpuscles in the preceding figure, 
and having very much the appearance of being formed out of such cor- 
puscles. Some of them were beginning to send out a process, and they 
were all lying in nearly the same direction (par. 49.).
