The number of mesonephric tubules which join with the rete, 

 as described by Allen and others, varies in the specimens examined 

 from eleven to nineteen or twenty. The rete cords do not always 

 meet the glomeruli, but in man not infrequently connect with the 

 proximal part of the mesonephric tubule. This is the result of the 

 course taken by the ventral tubules in the human mesonephrost 

 as described above, for the rete seems to join with the neares, 

 part of the tubule. Tubules thus tapped along their course are,

by a rearrangement of their parts, brought to seem like two tubules 

 each arising from the rete, one running to the duct, the other end- 

 ing blindly, usually with an expanded end. Such a blind tubule 

 may be seen in fig. 4, 2, and in a fetus of seven months I have 

 traced five or six similar tubules. It is probable that these are 

 the tubules of the appendages of the rete testis, as described by 

 Roth and Poirier, and also the upper, shorter ductulus aberrans,
