In the summer a lamp may be kept burning in the fireplace or grate; flues must in some way be kept heated or they will not draw. Stoves assist ventilation to some extent, but furnaces and radiators do not assist at all to ventilate, and the air is thereby especially dry. A pan of water may be kept boiling in the room, or perhaps merely setting on the stove, or a towel or two may be hung near a radiator and kept constantly wet; these will dampen the air by evaporation, and this is often necessary when the rooms are kept warm by artificial heat. About 66° is a proper temperature for a sick room in most cases, but 60° to 65° is suitable for fever cases; feeble and emaciated persons require a temperature of 70° to 75°. Be careful to have the room warm when the patient is out of bed. THE SYMPTOMS OF INFLAMMATION. The ordinary symptoms which characterize inflammation may be known if we observe what takes place when an external part is injured. Let us suppose that a healthy man has a piece of glass stuck in his arm. He soon has pain, then redness in that part of his arm, then swelling, which is hard near the injury, and increases so that some swelling may be observed, though not so hard at a little distance, and the part is quite tender and hot. These are the ordinary symptoms of inflammation: pain, redness, heat, and swelling, with tenderness that is manifested when the part is pressed. If the inflammation increases there are signs of disorder in other parts of the body; the patient may be first chilly and feeble, then the skin may become hot and dry all over the body, the pulse fall hard and frequent, lassitude comes on with headache, perhaps pain in different parts of the body; he has also other symptoms of fever; is restless, sleeps ill, loses his appetite, his tongue becomes white, his mouth is dry, he is thirsty, the secretions of the body are diminished, has what is called inflammatory fever, or sympathetic fever, or pyrexia, the last term being now most generally used. These phenomena, this inflammation, ends in two or three different ways. If measures have been taken for subduing the inflammation—in the supposed case of the arm—if the glass has been removed, it will probably happen that the symptoms above named will disappear. This is to end in what is called RESOLUTION.
