General insensibility of surface (worse, back and abdomen); rubbing and pounding borne without pain, and is grateful on account of warmth produced. Finger-ends thickened, horny; insensible to pinching and pricking. Instantaneous voice-producer (Coca).

Respiratory.--Acute hoarseness. Throat and nostrils burn. Sits bent forward with dry cough. Pharynx and larynx feel dry, and the voice weak and toneless. Rawness and soreness of chest and throat. Cough of children caused by naso-pharyngeal catarrh; mucus drops from posterior nares.
