The Preface.
BEcause the Cure of diseases must be varied according to the variety of the temper, not onely of the body in generall, but also of each part thereof; the strength, figure, forme, site, and sence thereof being taken into consideration: I thinke it worth my paines, having already spoken of Tumors in Gene∣rall, if I shall treate of them in particular which affect each part of the body, beginning with those which assayle the head. Therefore the Tumor either affects the whole head, or else onely some particle thereof, as the Eyes, Eares, Nose, Gumms and the like. Let the Hydrocephalos, and Physocephalos be examples of those tumors which possesse the whole head.
