    Aeticle II.—Valvulak Thrills. A valvular thrill is a quivering sensation felt by the hand applied to the region of the heart in certain forms of disease. The likeness to the purring of a cat led Laennec^ to invent the name ** fremissement cataire for the pheenomenon : by its discoverer, Corvisart, it had been before described under the term bruissement. For a thrill to be of value as a physical sign it must be well marked : what may be considered a well- marked thril] can be learnt by experience alone. Tlirills are palpable mm-murs, and are due to the same physical condition; that is to say, to the vibration of a fluid vein. The vibration must be strong and slow in order to be palpable. The solids also must be apt for conduction; in other words, apt for con vibration : they must be elastic, tolerably homogeneous, and of a certain mean tension. Along fluid currents, thrills are conducted according to the laws of murmurs.^ * Ti-ait6 de I'auscultation mediate et des maladies des poumons et du ccem-. 2nd edit. ii. p. 448.
