tioned: Which assures me farther that this is a mere Scheme or Congeries of vessels.
I have made several other Experiments of this kind, about other parts of the Body; not to mention the Muscles, Heart, and Kidneys, because I suppose, that few men will now undertake for a parenchyma in them. And as I have opportunity, I shall shew, I hope, that all forts of Glands (so called) are nothing else but Vessels (and their Liquors) variously wrought, and receptacles of several Liquors for divers uses; the difference of which alters their Colour, Consistence &c. My meaning is, that there is in no reputed Gland any other thing, than in the Body of the Testis, viz. That it hath not this or that intermediate substance, but that the Liquors, regularly come and goe to and through them in fine tubes (in such and such heaps and figures, as may make them appeare so and so form'd in several parts of the Body, where they are scituated;) As also, that the more conspicuous Vessels of the Body have other vessel, that help to makeup their Coats, and serve for the nourishment of the same, besides such, as import or export those liquors, for the conveyance of which they were designed for common use. But of this hereafter, as occasion shall serve.
So farr Dr King: Aa to Dr. de Graeff, we shall deliver what he lately imparted to us upon this subject, in his own words, extracted out of his Letter dated July 25. 1669, at Delst: accompanied cum Testiculo Gliris dissoluto, & transmisso in Spiritu vini; represented in Fig. II.
Quod Clar. D. Clarck ait, Se parenchyma (quod succum quendom denotare dicit assusum vel effusum & aliquomodo concretum in vasculorum & fibrillarum interstitiis,) in Testiculis vivorum & aliorum etiam animelium, testimonio sensuum oftendere posse; hoc Ego, pace tanti viri dixero, nonnise Autopsià edoctus admittere possum. Quandoquidem sæpissimè Hominum aliorumque Animalium testiculos, exceptis tenuis simis quibusdam membranulis, ita dissolverim, ut ne umbra quidemtalis parenchymatis remaneret; imò, quod magis est, quorundam Animalium testiculos ita dissolvi, ut visus acie no quidem membranulæ illa conspicerentur. Et ut verba mea factis comprobem, mitto ad Te Gliris testiculum meo modo dissolutum, ut videas, an Glandule tales in Testibus (qua-les
