I now reproduce here two sphygmographic tracings whichmy friend Dr. Oliphant Nicholson has recently obtained, one from 138 ANTENATAL PATHOLOGY AND HYGIENE an infant five minutes old (Fig. 25) and tlie other from a child of sixdays (Fig. 26), both in perfect health; it will be noted that in boththere is relatively high tension, a well marked apex, and tidal anddicrotic wavelets. It may therefore be concluded that, with a delicatesphygmograph and sufficient care in employing it, such tracings are ob-. FiG. 25.
