The workes of that famous chirurgion Ambrose Parey translated out of Latin and compared with the French. by Tho: Johnson. Whereunto are added three tractates our of Adrianus Spigelius of the veines, arteries, & nerves, with large figures. Also a table of the bookes and chapters.

CHAP. XXI. Of the original of the Artery, and the division of the Branch, descending to the natural parts.

THese things being thus finished and considered, the guts should be pulled away; but see∣ing that if we should do so, we should disturb and lose the division of the artery descen∣ding to the natural parts; therefore I have thought it better to handle the division there∣of,* 1.1 before the Guts be pluckt away. Therefore we must suppose, according to Galen's opinion, that as all the veins come from the Liver, so all Arteries proceed from the Heart. This presently at the beginning is divided into two branches, the greater whereof descends downwards to the natural parts upon the spine of the back, taking its beginning at the fifth vertebra thereof, from whence it goes into the following arteries. The first, called the intercostal, runs amongst the intercostal muscles, and the distances of the ribs, and spinal marrow, through the perforation of the nerves on the right and left hand from the fifth true, even to the last of the bastard ribs.

* 1.2This in going this progress makes seven little branchings, distributed after the forementioned manner, & going forth of the trunk of the descendent over against each of the intercostal Muscles.

The second being parted into two, goes on each side to the Midriffe, whence it may be called, or expressed by the name of the Diaphragmatica, or Phrenica, (i) the Midriffe Artery. The third being of a large proportion, arising from the upper part of the Arterie presently after it hath passed the Midriffe, is divided into two notable Branches, whereof one goes to the Stomach, Spleen, Kall, to the hollow part of the Liver and the Gall; the other is sent forth to the Mesen∣tery and Guts after the same manner, as we said of the Meseraick vein, wherefore it is called the Coeliaca, or Stomach Artery. But we must note, all their mouths penetrate even to the innermost coat of the Guts, that by that means they may the better and more easily attract the Chylus con∣tained in them.

* 1.3The fourth carryed to the reins, where it is named the Reinal or Emulgent, because it sucks fit matter from the whole mass of blood.

* 1.4The fifth is sent to the Testicles with the preparing Spermatick-veins, whence also it is named the Spermatick Artery, which arises on the right side, from the very Trunk of the descendent Artery; that it may associate the Spermatick-vein of the same side, they run one above another, beneath the hollow-vein; wherefore we must have a great care whilest we labour to lay it open, that we do not hurt and break it.

The seventh Figure of the lower Belly.

• A, A, The Midriff turned back with the ribs of the Pe∣ritonaeum.
• BB, The cave or hollow part of the liver; for the liver is lifted up that the hollow part of it may be better seen.
• C, The least ligament of the Liver.
• D, The Umbilical vein.
• E, The hollowness of the Liver, which giveth way to the stomach.
• F, the left orifice of the stomach.
• GG, Certain knubs or knots, and impressions in the hollow part of the liver,
• H, The bladder of Gall.
• I, The Gate-vein cut off, and branches, which go to the bladder of gall.
• K, A nerve from the liver coming from the stomachi∣cal nerve.
• L, An Artery common to the liver, and bladder of gall.
• M, A nerve common also to them both, coming from the right costal nerve of the ribs.
• N, The passage of the Gall the Guts cut off.
• OO, The hollow of the fore-parts of the Spleen.
• P, The line where the vessels of the Spleen im∣planted.
• Q. The trunk of the hollow veia.
• R, The trunk of the great Artery.
• S, The Coeliacal Artery cut off.
• T, V, The Kidneys yet wrapped in their membrane.
• X, Y, The fatty veins called venae adiposae.
• a, b, The Emulgent veins with the Arteries under them.
• cc, dd, The Ureter from either kidney to the bladder.
• e, f, The spermatical veins to the testicles; the right from the hollow vein, the left from the Emulgent.
• g, g, Veins coming from the spermatical to the perito∣naeum.
• h, i, the spermatical Arteries.
• k, The lower mesenterical Artery.
• l. The ascending of the great Artery above the hollow vein, and the division of it, and the hollow vein, into two trunks.
• m, The Arterie of the loins called lumbaris. n, The holy Artery called Sacra.
• o, A part of the right gut.
• p, The bladder of Urine. * The connexion of the bladder with the peri∣tonaeum.
• q, A part of the vessels which lead the seed from the Testicles is here reflected.
• r, s, The scrotum or cod, that is, the skin that invests the Yard and Testicles
• t, The fleshy Pannicle or membrane which is under the cod.
• u, The coat which is proper to the Testicles with his vessels.
• x, A part of the yard excoriated or flayed, and hanging down.

The sixth going from the fore and upper part of this descend nt artery,* 1.5 descends with the Hae∣morrhoidal veins to the fundament; presently from his beginning, sending forth certain branches alongst the colick gut, which by Anastomasis are united with other branches of the Coeliacal Arte∣rie; for whosoever shall look more attentively, he shall often observe that veins are so united amongst themselves, and also arteries, and sometimes also the veins with the arteries. For Ana∣stomasis is a communion and a communicating of the vessels amongst themselves by the applicati∣on of their mouths, that so by mutual supplies they may ease each others defect. But they call this the lower meseraick artery.

The seventh proceeding from the trunk with so many branches as there be Vertebra's in the loins, goes to the loins, and the parts belonging to them, that is, the spinal marrow of that part,* 1.6 and other parts encompassing these Vertebra's, whereupon it is stiled the Lumbaris, or Loin-Ar∣tery.

The eighth maketh the Iliack arterie, until such time as it departs from the Peritonaeum, where the Crural Arteries take their original. This Iliack Artery sends many divarications towards the Holy bone where it takes its beginning, and to the places lying neer the Holy bone, which,* 1.7 be∣cause they run the same course as the Iliack veins, for brevitie's sake, we will let pass further men∣tion of them, till we come to treat of the Iliack veins.
