It is proper to observe, that animals who arrive slowly at maturity, are the longest lived, and of the noblest species. Men cannot, however, claim any natural superiority from the grandeur of longevity; for in this respect nature has not distinguished the male. Polygamy is another physical degradation; and a plausible argument for a custom, that blasts every domestic virtue, is drawn from the well-attested fact, that in the countries where it is established, more females are born than males. This appears to be an indication of nature, and to nature apparently reasonable speculations must yield. A further conclusion obviously presents itself; if polygamy be necessary, woman must be inferior to man, and made for him. With respect to the formation of the foetus in the womb, we are very ignorant; but it appears to me probable, that an accidental physical cause may account for this phenomenon, and prove it not to be a law of nature. I have met with some pertinent observations on the subject in Forster's Account of the Isles of the South Sea, that will explain my meaning. After observing that of the two sexes amongst animals, the most vigorous and hottest constitution always prevails, and produces its kind; he adds,--"If this be applied to the inhabitants of Africa, it is evident that the men there, accustomed to polygamy, are enervated by the use of so many women, and therefore less vigorous; the women on the contrary, are of a hotter constitution, not only on account of their more irritable nerves, more sensitive organization, and more lively fancy; but likewise because they are deprived in their matrimony of that share of physical love which in a monogamous condition, would all be theirs; and thus for the above reasons, the generality of children are born females." "In the greater part of Europe it has been proved by the most accurate lists of mortality, that the proportion of men to women is nearly equal, or, if any difference takes place, the males born are more numerous, in the proportion of 105 to 100."
