The size of the Testes vary in different persons. The average of mankind have them each about the bigness of a pigeon’s egg; but sometimes they are larger. It seldom makes any difference in the actual power of procreation whether these organs are large or small, though persons with large Testes can generally perform the act of copulation oftener, and with less exhaustion. A man with large Testes generally has a large Penis, as the size of the one usually governs the growth of the other; but it is by no means certain that sexual connection thereby affords him any more pleasure. Such men should marry with great caution. Many females are incapable of affording them pleasure from the comparative smallness of their private parts; and they suffer much pain and ill health from such intercourse. On the contrary, men whose genital organs are not fully developed, though they may impregnate, yet they cannot always give full satisfaction to the female. If it could so be that people about to marry were properly matched in their private parts, it would prevent a great deal of unhappiness in the world. [Illustration: MALE PRIVATE PARTS ...

One of the Princes of the Royal Family of England (a son of George III.) died without legitimate issue because he could not have connection with his wife—she being too small, or he being too large for the purpose. It is true, he was entitled to a divorce by law, but it was said he respected his wife too much to resort to such a measure. Another curious case was that of Baron Brunner, whose wife claimed a divorce on the ground that her husband was a sort of eunuch, who could afford her no pleasure during connection. But in this case, as Madame was the mother of a daughter, to whom she dared not deny the paternity of the Baron, her petition was rejected.
