If a person without any premonitory symptoms is seized with a chill, followed by rapid breathing, a dull pain in the chest, cough, high fever, and comparatively slow pulse; if the thermometer indicates a temperature of 104° or 105°, and the pulse does not beat over 110 a minute, the case is one of ACUTE PNEUMONIA. Sometimes the temperature is below 90°; if it exceed 120° it is almost certain to be fatal. AGUE. CHILLS recurring regularly for a few days indicate the intermittent nature of a disease. But during the first chill if the thermometer is applied, we may know that a case is one of fever and ague, if while the skin is yet cold the thermometer rises to 105°, and later to 107°, and during the stage of sweating the instrument shows a decline of 2° every fifteen minutes till it has reached 98½°. This rapid rise and decline is due only to malaria, and quinine is indicated. (F. 182.) TUBERCULAR PHTHISIS. If a patient has been losing flesh of late and been troubled with a short, dry cough, take his temperature at about six P. M. for a few evenings. If the thermometer records 99° to 100°, and no other cause exists for this regular nightly increase of temperature, the case can be put down as one of incipient consumption, especially if tuberculosis has been in the family. Endeavor to improve the general nutrition by attention to the quantity and quality of the food (as generous diet as can be taken without disturbing the stomach or increasing the feverish symptoms); by enjoining a residence in a healthy climate; by exercise in the open air; by warm clothing; by daily tepid sponging, with friction of the skin; and by cod-liver oil or petroleum emulsion with hypophosphites. An animal diet is generally necessary. If digestion fails and there is acidity of the stomach, give pepsin. (F. 72.) Add a teaspoonful of sweetened lime water to a tumbler full of milk, and if this agrees with his stomach, he can take that amount four times a day. In TYPHOID FEVER the patient may complain of lassitude, headache, pain in the back, etc., for several days before he is feverish. Then his temperature is 99°, and it may be one degree higher each night, until on the sixth and seventh evening it is 104°; it being each morning one degree less than at night. Even if there is no diarrhœa, tympanitis, or eruption, we may by observing the temperature, feel sure that we have a case of typhoid fever. If it is a moderate case the temperature will be 104° at night, and 103½° in the morning, till the fourteenth day, when it may decline one degree in the morning, and half a degree or one degree in the evening. After that it may decline regularly till on the 21st day it may be 98½°. Relapse or chest difficulty may modify this regular decline, and the nurse must carefully note and report to the physician the temperature each morning and night.
