Note 814 — ON INJURIES OF THE HEAD.
Francis Adams translation
The operation here described by our author is the more deserving of attention, as it appears to have been peculiar to him. It is not described by Celsus, Paulus Ægineta, Albucasis, nor any one of the ancient authorities, as far as I can find; neither am I aware of its having been attempted in modern times. The object of it, however, seems to be very rational, namely, to avoid doing serious injury to the dura mater by tearing the bone forcibly from it at once.
