 ON PARTURITION. 527

tenth month. Both laws and precepts of art, we must remem- ber, have reference to the general rules of vital processes. Besides, it is impossible to deny that many women, either for purposes of gain or from fear of punishment, have simulated pregnancy, and not hesitated to swear to the truth of their assertion : others again have frequently been deceived, and fancied themselves pregnant, whilst the uterus has contained no product of conception. On this point Aristotle's 1 words may be quoted : " The exact period at which conception takes place in the case of those born after the eleventh month can scarcely be ascertained. Women themselves do not know the time at which they conceive ; for the uterus is often affected by flatu- lent disorders, and if under these circumstances conception takes place, women imagine this flatulency to mark the period of conception, because they have recognized certain symptoms which accompany actual conception."

In the case of other women in whom the foetus has died in the third or fourth month, then putrefied, and come away in the form of fetid lochial discharges, we have known superfoeta- tion to take place ; and yet these same women have persisted that they have brought forth their children after the comple- tion of the fourteenth month. " It happens sometimes," says Aristotle, 2 " that an abortion takes place, and ten or twelve products of superfoetation come away. But if the (second) conception takes place soon after (the first), the woman goes to the full time with the second, vand brings forth both as twins. This was said to have been the case in the fable of Iphicles and Hercules. And it is a subject which admits of proof; for it is known of a woman that she brought forth one child resem- bling her husband, and another like a man with whom she had had adulterous intercourse. Another woman became pregnant of twins, and conceived another by superfoetation. Her labour came on, and she brought forth the twins well formed and at their proper time, whilst the third child was at the fifth month, and so died immediately."
