MorgagniJ was the first who accurately described the Weberian organ, which he also probably discovered. Of fifteen human bodies which he examined with this object, he found it in fourteen. It is possible that in the one remaining case he overlooked it, since it sometimes happens that its mouth is but small, or is even altogether deficient, as Huschke has frequently ascertained it in healthy and robust suicides. Nevertheless it is not improbable that in some cases there is a complete absence of the Weberian corpuscle; the less so that we sometimes verify such dif- rences in other animals. In two of these fifteen cases, Morgagni found that the utri- culus, instead of opening by a special aperture, communicated with one of the ejaculatory * See PROSTATE, Vol. IV. fig. 103. f Zur Morphologic der Ham- u.

But at all events this is a rare ano- maly, which has been since observed by Adams only.* In a case mentioned by Hyrtif, there was a simultaneous deficiency of both vesicuke seminales, and the ejaculatory ducts descended into the upper end of a single receptacle, which was one inch long and seven lines broad. But though Hyrtl and Thtile regarded this structure as certainly an uterus masculinus, and thus as a Weberian organ; yet the in- sertion of the ejaculatory ducts at the upper end is a circumstance which contradicts their view.
