90 The Rete-Cords and Sex-Cords of Chrysemys 
medullary cords of the ovary, as the case may be. The proximal portions 
of these funnel-cords go to form a large part of the rete-testis-ovarii, 
while the more distal portions join the adrenal fundament and contribute 
the major portion of the cortical substance of that organ. 
This leads me to briefly consider the adrenal body, although this was 
not within the original plan of the present work. Soulié, 02, finds that 
in Lacerta and the chick, the cortical substance arises wholly from cords 
of cells proliferated from the peritoneum mediad of the sex-gland and 
at the base of the mesentery. He states, however, that these cords become 
closely applied to the capsule of Bowman of the Malpighian corpuscle. 
It is difficult to understand how, arising from the base of the mesentery, 
they could reach the Malpighian corpuscle without growing dorsad along 
the medial side of the V. renalis revehens to the adrenal body fundament, 
and thence laterad and ventrad to the Malpighian corpuscle. It is diffi- 
cult to understand how they could take this course, without passing 
through and beyond the fundament of the adrenal body. There certainly 
are, 1n the turtle, cords of cells that arise as Soulié and others claim, near 
the base of the mesentery, and these contribute to the formation of the 
adrenal body; but certain sex-cords and the funnel cords contribute to 
it as well, and in even greater measure. Brauer, 02, also holds a view 
similar to that of Soulié as regards Hypogeophis one of the Gymnophiona. 
Poll, 03, reached similar results with the Elasmobranchs, Acanthias and 
Spinax. Be this as it may, I feel quite sure of my ground in the case of 
Chrysemys, and the work of Weldon, 85, and Hoffmann, 89, would lend 
color to this view, though they hold views in some points radically differ- 
ent from mine. 
In this connection it may be well to state that several of Hoffmann’s, 
89, figures of the “ Sexual Strange” would serve fairly well to represent 
the funnel-cords as I have seen them. They certainly do not prove 
his contention that the cords in question, sex-cords and adrenal-cords, 
arise from the capsule of Bowman; although he has so interpreted them. 
Those who held view C, probably used insufficient material and lacked 
the intermediate stages between the period just before the formation of 
the sex-cords and those subsequent to their separation from the germinal 
epithelium. 
Janosik, 85, D, worked upon the chick. It is quite possible that future 
work may in large part substantiate his results for that form. My results 
agree with his as regards the origin of the sex-cords,: but differ from his 
upon the origin of the rete-tissue, although even here there may be a 
reconciliation between our views.
