Before he can become a doctor, he must gain a capacity for discriminating between sense stimuli.
The same may be said for the pulsations of the heart, which the student studies in theory, but which the ear can learn to distinguish only through practice.
We may say the same for all the delicate vibrations and movements, in the reading of which the hand of the physician is too often deficient. The thermometer is the more indispensable to the physician the more his sense of touch is unadapted and untrained in the gathering of the thermic stimuli.
