CHAP. XIIII. Why Mules be barrain. [ 40]
ALCMAEON is of opinion, that Mulets, that is to say, male Mules be not able to engender for that their seed or geneture is of a thin substance which procecdeth from the coldnesse therof. The Females also, because their shaps do not open wide enough, that is to say, the mouth therof doth not gape sufficiently; for these be the verie tearmes that he useth.
EMPEDOCLES blameth exilitie or smalnesse, the low positure and the over streight confor∣mation of the matrix, being so turned backward and tied unto the belly, that neither seed can be directly cast into the capacitie of it, nor if it were caried thither would it receive the same. Unto whom DIOCLES also beareth witnesse saying, Many times (quoth he) in the dissection of Anatomies we have seene such matrices of Mules; and it may be therefore, that in regard of [ 50] such causes some women also be barrain.
