The amplitude is notgreat, the line of ascent isoblique, the summit rounded,the descent gradual, and thesecondary waves characters are shownin Fig. QQ, which is the copyof a tracing obtained from oneof my patients who presentedthe signs of pure and uncom-plicated narrowing of theostium, there being no dias-tolic murmur of regurgita-tion, and the left ventriclehypertrophied with very littledilatation.
