There is one experiment of Erasistratus's, mentioned by Galen, which appears to have given rise to their doctrine of the arteries absorbing air and finer fluids: perhaps this might induce them to suspect that the veins too absorbed. It will appear afterwards, that Era- sistratus was, in that experiment, deceived; that they were not arteries, but laeteals, which he saw,- and that it was not air, but ehyle, which they had absorbed; of course, that there was no just reason for the doctrine of ar- terial absotptiou. The discovery of the Circulation of the blood (lemon- straietl that the Course of the arterial fluids was constantly from the centre oi~ the body to the circumference, that is, perfectly opposite to that of absorbed fluids, or such as are supposed to be passing from the Cirt‘utnkrence to the Centre; and this overturned entirely that doctrine."
