Circulation of the Blood

The passage in Venerable Bede referred to by J.MN. may have been in a tract *De Minutione Sanguinis sive de Phlebotomia*; (which occurs in the folio editions, Basle, vol. i. p. 472.; Colon., vol. i. p. 898.). In the enumeration of the veins from which blood may be taken, he says,— "De brachio tres, *qui per totum corpus reddunt sanguinem*, capitanea linea, matricia, capsale." The subject of bleeding is again referred to in *Eccl. Hist.*, vol. iii, but not to the purpose.
