 ments, which can be easily recognized in the adult testis, marking 

 subdivisions of the parenchyma between the septa. Jj^ 



The greatest complexity of convolutions is in the peripheral 

 part of the gland, and apparently in the cross connections, not in 

 the radial cords, which latter may frequently be seen in the adult 

 running from the rete with only a slightly wavy course to a con-

 diagram (fig. 2) gives the approximate course of several tubules 

 in a fetus of seven months and suggests from what part of the 

 original network they have been derived, while the model (fig. 11) 

 shows the actual form of some of the tubules at the same age. In 

 the adult I have been unable to follow completely any single tubule 

 but from the portions studied I feel convinced that, except for
