The instance of the Horatii and the Curatii, and their famous battle, on which hung the fate of Rome and Alba, is familiar to every one, their strength and wisdom being legendary with the Romans.
Twins and triplets, being quite common, will not be considered here, although there are 2 cases of interest of the latter that deserve citation.

Sperling reports 2 instances of triplets; in the first there was 1 placenta and chorion, 2 amnions, and the sex was the same; in the second case, in which the sexes were different, there were 3 placentas, 3 chorions, and 3 amnions.

What significance this may have is only a matter of conjecture.

Petty describes a case of triplets in which one child was born alive, the other 2 having lost their vitality three months before.

Mirabeau has recently found that triple births are most common (1 to 6500) in multiparous women between thirty and thirty-four years of age.
