So that, as Learned Dc Oraaf will have it, If you put a Blow-pipe into one of the Veins, the Branches wrll [well immediately; which hath fo far impofed upon fome over ci'edulous Anatomifls, as to make them believe upon this account, that the Veins have Inofculation with the Arteries , which cannot at all be evinced by this Experiment, becaufe the Branches of the Fpermarick Arteries, having no immediate entereourfe with the Veins, are not puffed up by the inflation of them, lo that the Arteries remain lank, a: unconcerned in the Dilatation of the Veins, when they are blown up with enfpited Air. 52;: In the Sperinatick Venis, two or three Remarks do occur : The firfl is, That their inward Region is befet with many Valves, not only about their egrefs near the Crl‘Z/rl, and Emulgent Veins, but alfo through their whole progrefs toward the 'l‘efticles, as f0 many I ocks to promote the lireams of The 5' not: Tumo f Blood in their current upward toward the (117/11, and to bound its tecourfe downward toward the Teflicles. The fecond obfervable is, That thefe Veins are often defaced with vari- .ng coll- Tumors, chiefly about the Valves, produced as I conceive, by a grofs Mali; of Blood, which flopping about the Valves, doth enlarge the Coats of the Veins, and render the Pyramidal body knotty, and Varicofe. ilrizhrhlidig The third remark is, which divers Antient Anatoniills have not obferved: Sgiiiiliom That the Veins do not keep the fame uniform progrefs with the Arteries, nicAumts. V\ hich in them is more flraight 3 but the coui'fe of the Veins is more crooked, and full of labyrinths, by reafon they emit great variety of Branches upward, and do terminate within the Membranes, tefembling the Tendrels of Veins; whence the former Anatomifts have {tiled theft: Plexes of numerous Veins Corpm rPyramidale, and @aiizyiniflrmt. The tile of the Spermatick Veins, is to reconvey the fuperfluity of Blood, after it hath been lei‘vieeable to the Tefticles upward7 into the great Trunk of the C1714, and afterward into the right Auricle, and Chamber of the Heart, to enoble the Vital Liquor with Spirituons and Saline Particles, received from the Tellicles; which make the Blood more aftive and vivid: imparting vigor and l'trength to the whole Body. 80 that Perfous upon Caftration, made defiitute of thefe ufeful parts, which fpeak them pflfca?

Flex lodged in the lowefl. Apartiment. Sometimes the Spermatick Arteries and Veins being in conjunction with the Spinal Nerve, fpringing out of the 21 pair of Vertebral Nerves, and with the Crcmalter Mufcle, do pafs out of the Cavity of the more free z'lbtlamcn, into the more lltraight enclofure of the Stratum, through a.

The Spermarick Veins into final] Branches, are entangled with the Arteries, and interwoven with each other, after the manner of a'cnrioully wrought Network; and the Veins do not only accoaft each other in fuper- ficial embraces, but have a more intimate converfe by mutual Inoleulations, by a perforation made through the Coat ofpne Vein into 1tsafl0crate,wherein they hold an entercourfe by the tranfmiflion of Vital Liquor, out of one Vein into another. But on the Other fide, the Preparing Arteries, contrary to the opinion of many Anatomiils, do not Inofculate with Veins: Perhaps divers have been mif‘taken, by reafon the Spermatick Arteries are frequently in comuné‘tion with the Spermatick Veins, which is no true Aliaflomofis, becaufe the alfociation of the Arteries and Veins is only fuperficial', and there is no Aper- ture interceding, thofe Vellbls of diHErent kinds, f0 that they have no near correfpondenedwith each other, by the transfulion of Liquor out of the Atteries into the Veins, if they were related to each Other by mutual [nofiularions. And this may be rendred clear Experiméntallyby making a Ligature i1p~ lantryof Mind, Strength, and Afiivity of Body, as well as the excellency 0f on the Preparing Veflizls near the Telticles, and a quantity of Liquor being l‘)?ifif‘°"i3§3: the Intellectual Faculties.
