monary Vein 3 of which I have added two Figures Cvict* 
Fig. I. and n.) drawn after a Preparation of that Vein 
injefted with Wax, and freed from the Lungs of an Adult 
Humane body. The Original Preparation is to- be feen 
among the Anatomical Colleftions of the Accurate 
Dr. Tj/fof^. 
Among many very confiderable parts of the Humane 
Body, not ill expreft in the Tables, publifhed by Bidloo^ 
and overlookt, or not known by him, this Trunk of the 
Pulmonary Vein is one 5 unlefs he may be allowed to call 
it the Left Ventricle of the Heart, as he has doneTab.22. 
Fig. 7. A. which miftake and omiffion, tho very grofs, I 
correfted, without refleding, or taking notice of the fault 
of the Profeflbr, and fome hundred others of that work, 
tho I could not poffibly avoid naming him on near forty 
other fuch occafions, in my explication of thofe Tables, 
publiftied not long fince in Englifh^ of which and the reft 
perhaps more hereafter. 
The Trunk of this Vein is very ill expreft in the xxxth 
Table of Kerckringiuss Anatomical Obfervations, as will 
appear by comparing it with thofe here. However, fome 
later writers of Anatomy have been contented to borrow 
it, without obferving the fault. 
. The Left Auricle of the Heart (vid,T\g, LIL) in Hu- 
mane Bodies being much lefs than the Right, it was necef- 
fary that the part of this Vein next the Bafis of the Heart 
flaould be very large ^ Qh. A A B ) left the fudden ftrong 
motion of the Syjtok fliould caufe the Refluent blood to 
recoil in the branches of this vein (ib. D D E E) and pre-

But the weight of fo much Blood lying in the trunk of 
this VelTel (ib, A A. B ) does effeftually prevent its retro- 
cefl,ion in the lateral branches within the Lungs ^ Qb. DD.
