Chapter XIV.

How it Arises that Mules¹ are Barren.

Alcmaeon says, that the barrenness of the male mules ariseth from the thinness of the genital sperm³, that is, the seed is too chill; the female mules are barren, because the womb does not open its mouth (as he expresses it). Empedocles, the matrix of the mule² is so small, so depressed⁴, so narrow, so invertedly growing to the belly⁵, that the sperm cannot be regularly ejaculated into it, and if it could, there would be no capacity to receive it. Diocles concurs⁶ in this opinion with him; for, saith he, in our anatomical dissection⁷ of mules we have seen that their matrices are of such configurations⁸; and it is possible that there may be the same reason why some women are barren.
