 where it disappears ; from this are given oil a large number of tibrilho

 by the vas deferciis, .-In.ws that this part of the testicle is chiefly formed 

 by a ramifying system of rectilinear canals with very thin walls, which 

 open into each other, and unite, on reaching the corpus Hi^hnmri, into 

 alnmt twenty principal trunks. These are named the straiylit rait<il!<-nll (vasa 



i. to distinguish them from the convoluted tubnli ; they receive the 



r at their exit from tk.; lobules, and are surrounded by numerous blood- 

 vessels and sustained by the fibrous septa of the tunica albuginea, which 

 appear to converge towards the point they occupy. At the corpus Ilighmori, 

 the vasa recta pass through that body, forming in its texture an anasto- 

 mosing network, the rete testis, and are continued into the epididymis as the 

 efferent cmml* (vasa efferentia). 



The semi nif trims tube* in the lobules 

 are from , .', -, t > the , I,, of an inch in 

 diameter. They are composed of a 

 very thin fibrous membrane (firmer 

 than that in the walls of similar gland 

 canals elsewhere); slightly elastic, 

 and made up of connective tissue 

 witli longitudinal nuclei, this mem- 

 brane is lined internally by a proper 

 amorphous membrane (basement) and 

 epithelium. The latter almost com- 

 pletely fills the tubuli ; near the wall 

 of the canal it is composed of polygonal 

 cells, but towards the centre these in- 

 crease in volume, become circular and

 in various stages of transformation; 

 finally, in the axes of the tubuli can 

 be perceived spermatozoa and the 

 detritus of the spermatic cells.

 remarkable flexions, enters the upper 

 border of the gland, a little behind 

 the epididymis. It dors not imme- 

 diately plunge into its substance, how- 

 ever, but passes within the texture of 



mica albiigim a, along the border-; 



of the testicle, and forms a complete

ides of the organ, detaching line

proper tissue in accompanying the interlobuhir septa. (There is generally
