To all which, the curious Dr. _Beale_ now 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, {321} being very light for a Stone of that Bulk. He further describes to be of a whitish colour, lighter than Ash-colour; perchance (_saith he_) not unlike to that recited out of _Scaliger_ by Mr. _Boyle_ in his _Essay of Firmness_ pag. 238. _qui aeris contactis postea in gypseam tum speciem tum firmitatem concreverat_. It had no deep asperities, and had somewhat of an Oval figure, but less at one end, than a Hen-Egge, and bigger and blunter at the other end, than a Goose egge. This Stone, (so he concludes) is intended for the _Royal Society_, with the Testimony of the _Chirurgion_, that perform'd the Operation, and other Witnesses of special credit; where also will be annexed the _manner_ of Operation. It appears by this last clause (to add that on this occasion) that this Well-wisher to the Improvement of all usefull knowledge, has taken notice of that considerable _Collection of Curiosities_, lately presented to the lately nam'd Society for their _Repository_, by the Publick-minded Gentleman Mr. _Daniel Colwall_, a very worthy and useful Member of that Body: To which Repository whatsoever is presented as rare and curious, will be with great care, together with the _Donors names_ and their _Beneficence_ recorded, and the things preserved for After-ages, (probably much better and safer, than in their own private Cabinets;) and in progress of Time will be employed for considerable Philosophical and Usefull purposes; of which perhaps more largely in another place. * * * * * _A Relation of a kind of _Worms_ that eat out Stones._ This is taken out of a Letter, written by one _M. de la Voye_ to _M.
