![and soluble. Bat if in this place it were allowed communica- tion with the venous blood, the intention of nature might be frustrated; Leal Lealis seems indeed to have attempted to con- travene her decrees by his experience, but Winslow, Heister, and others have denied his grounds. For the communication of the arteries with the veins takes place above these ramifications, but not within them. Below however, upon the testis and epididymis, it seems probable that there is a communication not only between the arteries and veins, but also between the veins and arteries ; as in the intestines : see above. This has not indeed been hitherto observed, yet we may conjecture as much from the connexion of things, as well as from the fact that precaution is required to pre- vent the quantity of blood of good quality failing; and also from other signs, and from the circumstance that the little veins are more numerous and larger than the arteries, which would not be the case if all the venous blood without loss of time were de- rived away to other parts; and from this further, that these veins are absolutely without valves, which enables the blood to run back into these extreme parts, and to wait in readiness, as the state and condition demand. Thus the experiment of Leal Lealis seems readily enough to meet the fact, that the blood might pass into these venous vessels by injection through the arteries, or from above into the veins, or below into the [same.] The blood therefore of the better sort, is dispensed without any loss. But on these subjects more will be seen in the Chapters on the Testicles and the Uterus. Hence it follows that an ever new store, and an additional supply ever fresh, runs abounding in the very act of coition. This must happen if the veins com- municate with the arteries close to the testes and epididymides; but otherwise a quantity of the viler blood might run to the spot, and not only defile the seed but also burst the small ves- sels and capillaries. Furthermore, above this splitting of the vessels into threads, there seems to be a kind of place of re- serve, small though it be, for the arteries swell out a little below their origin. 14. One little artery communicates with another here, as in the body universally; whereby there is nothing proper in any one vessel, even the very least, that is not common to all.
