In the Weberian corpuscle of two new- born infants, H. Meckel-f- found a special variety of structure. It became thinner in its ascent, so as to be only permeable by a hog's bristle, and ended as a solid thread, which -separated by bifurcating. 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.
