It seemes, that the two Authors in these two Papers have met with almost the very same Observations; which they account New, about the Genitals in both Sexes; and that, the former having appeared in Print before the latter, the latter thought himself obliged, the self same day that the Epistle of De Graaf came out of the Press (as himself intimateth) to declare in this his Podromus, that, though he knowes not, whether the Observations of the former be altogether the same with his, yet to avoid dispute hereafter, he thought fit, in this Paper of his, to represent the short of his own un-borrowed Observations, concerning that Subject, till he should be able to publish a full history of the structure of those parts.
Touching De Graaf, he 1. Rejects the opinion of those, that teach a Conjunction of the Seminal Arteries with the Veins by visible Anastomoses, and that reckon the Testicles among Glanduls. 2. He affirms, that he hath often unravell'd totam substantiam testiculorum in ingenitem longitudinem. 3 He asserts to have shewd by a short way, Vesicularum feminalium cum vasis deferentibus communionem, magnitudinem, figuram, earumque in Urethram exitum. To which he faith to have added a very easie way of examining the Body of the Prostate. From the consideration of all which he concludes Unam esse solummodo materiam feminis, eamque in testibus generari, in vesiculis excipi, & inde in Urethram ejici, non per unum, ut vult Veslingius, sed duo foramina. 4. He affirmes to have an easier and more accurate way of dissecting the Penis than any other Anatomists he knows; and that he assignes to the Muscles thereof a farr other use, than hath been done hitherto. Of all which he intimateth, that he is ready to publish a Book, after he shall have received the thoughts of Dr. Sylvius: upon the Manuscript thereof. He concludes, that he hath contrived a New Instrument, whereby every one may give himself a Ciyster without any Denudation of the parts, or change of posture.
