primary albuginea, germinal cords and rete-blastem, we have to see 
the homologon of the testis anlage in man. 
But in a female body, processes of development take place in the 
cortical layer besides. Proliferation of the epithelium has taken place 
here regularly, (in the mean time). The connective tissue of the 
primary albuginea penetrates into the cortical layer and the cortical 
epithelium penetrates in many places through the primary albuginea, 
so that the line of demarcation between cortical layer and medullary 
layer is again a very vague one. In consequence of the interweaving 
of the cortical layer and the connective tissue, epithelial cords and 
epithelial balls develop (not very distinct in man) from which 
finally the primary follicles arise by further proliferation of the 
connective tissue. 
A complete epithelial layer remains finally at the surface of the 
ovary (germinal epithelium). The germinal epithelium still forms in- 
growths, but they contain very seldom primordial eggs. In any case, 
they have nothing to do with the ovogenesis and with the eggtubes 
of Priiicur. The name of “Keimschläuche” is in my opinion less 
desirable. I should prefer the neutral name of “invaginations épi- 
théliales” (von Winiwarter). They generally disappear later on. The 
germinal cords and the rete cords become rudimentary. The germinal 
cords grow into epithelial cords, lying in the medullary layer. 
Consequently they are generally called “medullary cords”. A number 
of tubules are left from the rete cords. They are lined with cubical 
epithelium and lie in the hilus ovarii or even in the mesovarium. 
Some medullary cords are still connected with the rete. The rete 
itself may still be attached to the rests of the pronephros (epoophoron). 
In the ovary described here (at least in the part I could examine) 
I did not find rests of the rete, but the ingrowths of the germinal 
epithelium and the medullary cords were present. With respect to 
the ingrowths of the germinal epithelium, the following may be 
said. They are probably a regular phenomenon in the ovaries of 
human foetuses. After birth they generally seem to disappear soon. 
A few communications on these ingrowths in infant ovaries are 
not very clear (cf. ScHOTTLAENDER. Archiv für mikrosk. Anatomie. 
Bd. 41, 1893). They occur more frequently in young animals and 
they are even regularly found in adult dogs. (ScumaLtz). From a 
figure in the book of ScnmaLtz we may conclude that they are 
considerably larger in the dog’s than in the human ovary, I de- 
scribe here. 
There is a great deal of literature on the medullary cords, which 
von Winiwarrer and Bönrer cite principally. It is evident that they
