“ SYMPTOMS OF DISEASE, WITH INSTRUCTION TO NURSES. Symptoms are the signs by which we know that disease is present. Every circumstance happening in the body of the sick person capable of being perceived by himself or others, which can be made to assist our judgment concerning the seat or nature of the disease, its probable course and termination or its proper treatment, is a sign or symptom. ”
