The right and natural birth is, when the child comes with its head first; and yet this is too short a definition of a natural birth: for if any part of the head but the crown comes first, so that the body follows not in a straight line, it is a wrong and difficult birth, even though the head comes first. Therefore, if the child comes with its feet first, or with the side across, it is quite contrary to nature, or, to speak more plainly, that which I call unnatural. Now, there are four general ways a child may come wrong. 1. When any of the fore parts of the body first present themselves. 2. When, by an unhappy transportation, any of the hinder parts of the body first present themselves. 3. When either of the sides, or, 4. the feet present themselves first. To these the different wrong postures that a child can present itself may be reduced. SECT. I. _How to deliver a Woman of a Dead Child, by Manual Operation._ When manual operation is necessary, let the operator acquaint the woman of the absolute necessity there is for such an operation; and that, as the child has already lost its life, there is no other way left for the saving of hers. Let him also inform her, for her encouragement, that he doubts not, with the divine blessing, to deliver her safely; and that the pain arising thereby will not to be so great as she fears. Then let him stir up the woman’s pains by giving her some sharp clyster, to excite her throes to bear down and bring forth the child. And if this prevail not, let him proceed with the manual operation.
