THE horror which these means of extraction naturally inspire, the damage and inconveniences inseparable from them, notwithstanding all the improvements pretended to have been made, have engaged several authors to imagine other less dangerous expedients. But before I mention them, I cannot well avoid taking notice of a suggestion of _Celsus_, if but to warn those whom it may concern, not to be too much carried away by the authority of a great _name_. IN such a case the method Celsus recommends, is, for one of the robustest men that may be got, to press strongly upon the belly of the patient, with his heavy hands, inclining them downwards, so that such a pressure may force out the head that shall have remained in the uterus. Is not this a right _learned_, and especially a very tender expedient? MAURICEAU and Amand giving a loose to their genius have proposed less perilous methods. _THE_ first tells us, that it came into his head, in this case, that a fillet of soft linnen might be made, in from of a sling, to be slipped over the head, and so bring it away. AMAND has imagined a silk caul, of net work, to wrap the head in. This caul is to be pursed up by means of a string, that gathers four ribbons fastened to four opposite points of the circumference, or opening of this kind of purse, by which the head so wrapped up is to be extracted. MR. Walgrave professor at Copenhagen has improved on the first scheme of a fillet, by stitching together the two extremities of a fillet of linnen of about two yards long and four or five inches wide, in which he makes three slits lengthways, to seize the head more firmly, and hinder the fillet from slipping off the rounder parts of it. The figure of it may be seen in a Latin work intitled, _Dissertation upon the separated head of a child, and the different ways of extracting it from the mother’s womb_. By Mr. John Voigt, at Giessen, 1749. MONSIEUR Gregoire, man-midwife at Paris, has disputed with Monsieur Amand the glory of this invention of the caul.
