''Observables Touching'' Petrification.

Hough much hath been already said and written of Petrification, yet 'tis conceived, that all that comes so far short of a competent stock for the composing of a perfect History of Petrification, that the incompleteness thereof ought to awaken the more diligent attention of the Curious, and to call in their aid for Additions, thereby so to increase and to complete the Materials for that work, that it may the better serve to clear and make out the Cause of that Transmutation. And that the rather, because if it lay in the power of humane Skill (by the knowledge of Nature's works) to raise Petrification, or to allay, or prevent it, or to order and direct it (which perchance in time might be attained the said way) much use might be made of this Art; especially if it could be made Applicable, to hinder the Generation of the Stone and Gravel in humane Bodies, or to dissolve the Stone, where 'tis formed; besides other valuable Uses, that might be excogitated.

Upon this Consideration, care is, and further will be taken in these Papers, to record, among other Observables of Nature, what shall be communicated of this kind of Change.

In  and  several Relations have been made belonging to this Argument. Much of it, together with considerable Reflections may be seen in Mr. Boyles Essay of Firmness: In Helmont de Ltihiasi, where, among other remarques, is recited the Testimony of Paræus, of a Petrified Child seen at Paris, and by the Owner used for a Whetstone: In Deusingiuss Historia Infantis in abdomine inventi, & in ducitiem lapideam conversi: In Mr. Hook'sMicrography, and in others. To omit now, what has been related (but perhaps not well enough attested) by Authors, concerning the stupendious Petrification of whole Companies of Men, and Troops of Cattle; by Aventinus lib. 7. ''Annal. Bojorum; by Purchas in his Pilgrimage'' p. 426. in fol. printed at London 1614. and, (of a Troop of Spanish Horsemen) by Jos Acosta lib. 3. c. 9.

To all which, the Curious Dr. Beale adds a Narrative of a Stone, not long since taken out of the Womb of a Woman of his neighbourhood neer Trent in Somersetshire, by incision, and afterwards perfectly cured, though she had born the Stone with extreme torments for 8. or 9. years. The operation he relates to have been made in Easter last; after which time, he affirms to have seen the Stone, and weigh'd it in Gold-Scales, where it wanted somewhat of four Ounces, but had lost of the weight, it formerly had, Rh
