    from tlie lungs in the layers of the Ugamentum latum pulmonis^ and joining the esophageal veins. As far as my observations go, these vessels do not return the blood from any part of the interior of the lungs, and are simply the small veins belonging to the areolar tissue between the folds of the ligament. Since the foregoing was written, and conse- quently after the conclusions above mentioned had been arrived at, on perusing that portion of the Essay of Reisseisen in which he treats of tlie bronchial arte- ries, and which portion had not previously attracted my attention, I found the following passage, which I quote entire: — The veins which carry back the blood received from the bronchial arteries, since they have a special character, either neglected until now or else esteemed as an irregularity, seem m.ost worthy of more accu- rate examination. For all the venules, which in the greatest portion of the lungs answer to the bronchial arteries, arc collected not into similar trunks, but their mouths open into the pulmonary vein through- out its whole course. In that part only of the bron- chial tubes nearest to the large vessels, and from a part of the vascular network, are the venules collected into a very small trunk, which passes into the vena azygos, or some other branch of the vena cava, or into the vena cava itself. It is called the broncliial vein. * * Venffi nnnr qnm snngninem ex arteriis bronchialibus accep- tum reveliunt, accuratiori examine, quum proprietatem jeferant, vel plane usque adhuc negleetatn, vel certe pro aberratione liabi. tarn, dignissimffi videntur.
