The pulse no longer possesses expressive value in its qualities of softness or fullness; but anatomo clinical experience made it possible to draw up a picture of the biunivocal correspondences between the appearance of the pulsations and each lesional type: the pulse is strong, hard, vibrant, and frequent in active aneurisms without complications; soft, slow, regular, easy to smother in simple passive aneurisms; irregular, unequal, undulating in permanent nm tractions; intermittent, irregular at intervals in temporary contractions; weak and scarcely perceptible in hardenings, ossifications, softenings; rapid, frequent, disordered, and almost convulsive in cases of the rupture of one or several bunches of fleshy fibres.
