womb and those of either side of the womb to the respective breast of which are most apparent footsteps in the fabrick of nature for though in some vessels as Blood-veins water-veins chyle-veins arteries c. this distinction of sides be again lost and confounded by insertion into some common Trunk before they can be traced from the one part to the other collateral part yet in some other vessels without any such confusion in the midway the same collateral vessels ramify themselves distinctly unto the parts all along on the same side as is most manifest in the visceral sinew or wandering pair but yet hereby is not opened any window to see into the sex of unborn conceptions And as herein I desire to reverence antiquity but follow reason so upon your more serious thoughts I doubt not but you will judge with me another Point upon this subject very well worthy calling in Question and that is the much noysed ground of this sympatly between the Breasts and womb said and formerly thought to be the inosculations of the mammary veins and Arteries with the Epigastriks It is well known how many lateral heterogeneal inosculations between Arteries and Blood-veins have been introduced by closet Anatomists while in Bloudless speculations they formed nature according to their reasonings to solve appearing phaenomena's instead of forming their reasonings according to what they ought first to have observed in nature the verity and authority of all which among Anatomists at sharp that carry their Eyes in their hands and will believe no more than they see is at present not much however formerly solemnly and for singular purposes placed in and very near several of the chief Bowels yet the fumultous aestuation which this Hypothesis continually placeth nature under like the meeting of two contrary seas may be sufficient in reason also to decry and discard it for which reason also lateral homogeneal inosculations of bloud-veins with bloud-veins as they are frequently found so they may as easily in reason be admitted But the inosculations in the Question being final I wave these that are lateral And final inosculations are on all hands agreed to be in a manner impossible to be shewn because when granted to be yet there where they are the vessels are so minute and slender that it neither can be easy for the quickest sight nor the most cautions hand either without hurting them to come at the vessels where they are inosculated or to distinguish the vessels when heterogeneal at their inosculation or to discern a final inosculation whether of vessels of the same or of different kinds So that this whole Question about final inosculations being to receive its decision by the judgment of reason such final inosculations as are homogeneal as of Arteries with Arteries and Bloud-veins with Bloud-veins of the same Trunk such as in this Point were understood and intended by the Antients are no way capable of desence allowance or justification at the Barr of reason for it experimentally and to the eye appears that if any such inosculations should be supposed the same Humours at the same time from the same place should move two contrary ways to wit both to and from the heart and in vessels rising from or gathered at after into the same trunk in which account the lung vein the hollow vein and the port vein though all of them bloud-veins yet because of the diversity of their Trunks are to be esteemed as heterogeneal And finall homogeneal inosculations generally and therefore also between the Mammaryes and Epigastricks being thus everted the old doctrine oncerning the ground of the sympathy between the Breasts and womb cannot be retained And if any think by a short alteration of and putting heterogeneal inosculations for the rejected homogeneal the ground of this sympathy will remain firm and clear as of old to wit by making humours to be transferred from the womb by the Epigastrick arteries and mammary veins to the Breasts and by the mammary arteries and Epigastrick veins from the breasts to the womb I suppose that though such inosculations be not as the other impossible though undemonstrable to sense yet upon mature considerations these will not be judged sufficient to found this sympathy upon If we lay the matter seriously in the ballance even such heterogeneal and final inosculations do rather hinder the transferring of humours from the one part to the other to be sure look how much salls or is any ways drawn into their capacities and cavities cannot by them be so transferred but is otherways disposed of for the mammarie veins carry not to the breasts but to the subclavians and so to the heart and the mammary arteries carry not to the breasts but to the Muscles and parts on the forebelly In like manner the womb will appear equally unconcerned in those veins and arteries for the Epigastrick veins carry not bloud unto the womb but unto their collateral Iliacks and so to the heart and the Epigastrick arteries carry not bloud from the Iliacks to the womb but to the Muscles lying on the fore part of the belly And of themselves neither mammary bloud-vessels reach the womb nor either of the Epigastricks the breasts so as notwithstanding any thing in these vessels we yet seem to be in the dark as to the grounds of this confessed sympathy Not to add that in many Animals some and in some all the breasts are quite out of the way of the Mammaryes on the same side of the Epigastricks with the womb and on that side as farr removed from the capillar terminations of the Epigastricks and mammaries as the womb it self And professedly I understand not upon what necessity the vessels founding or contributing to the sympathy of these two parts must needs pass directly between the one part and the other and may not as well here as in the sympathy of other parts be admitted sufficient for this purpose by their common concern and relation to some special branch or general trunk And vessells thus related touching and terminating in these two parts are not hard to be found in several kinds as arteries and sinews to convey like matter to both these parts veins and sinews to reduce what is improper superfluous useless or redundant in either or meet and apt to be transferred from the one to the other in which both cannot but be assisted by the agreement of their similar attractions and that conformity of substance which is either constant or at some special times between some or all of each of their parts which as it may be a ground of the maturation exalting of these parts together so thereby the Bodies pores and passages of both are alike open for the reception of like humours and the same conform substance may be the cause why those vital emanations irradiations which the generative parts receive from the parts which are principal when I say those vital emanations come to be remitted and reflected back again from the
