At the pointed extremity of each lobule thespermatic canals become straighter, when each by itself, or thetwo or three arising inone lobule united into asimple canalj enter as theductidi recti, [?^ in dia-meter (fig. 257c),the baseof the corpus Highmori,where they form a veryclose plexus, 2—3broadand Ir! thick, and ex-tending the whole lengthof that body,—the retetestis {r. vasculosum Hal-leri) (fig. 257 d). Fromthe upper end of thisplexus, the canals in whichmeasure from ^ to ?^(0-03—0-08), proceed7—15 efferent canals,vasa efferentia testis s,Graafiana, of \—^ (016—0-18) (fig. 257 e),Avhich^ traversing the t. albuginea are continued into theepididymis. Here they contract to ^ and ^, are convolutedin exactly the same way as the spermatic canals in the lobulitestis, but without presenting divisions or anastomoses, andthus produce a certain number of conical bodies^ theapices of which are directed towards t
