Influence of the Vessel Wall.—Since the experiments of already quoted (see page 49) showed that a pressure of1 mm. was always sufficient to close the lumen of an excisedradial artery, the error from this source may be absolutelyneglected. That a sclerotic vessel may offer considerableresistance to compression is, however, a common belief, whichI do not think is justified, v. Basch found the empty scleroticradial could be compressed by 5 mm. Hg. The digital arteriesshould give an even lower figure, but that the larger brachialwould offer more resistance seems plausible.
