The huskiness and loss of power of articulation so common among us are largely due to the use of steam for heating. The steam cannot be properly regulated, and the temperature becomes too high. A person living in this atmosphere has all the cells of the lungs open, and when he passes into the open air he is unduly exposed. The affliction is quite common among the men who occupy offices in the new buildings which are fitted up with all modern improvements. The substitution of electric light for gas has wrought a change to which people have not yet adapted themselves. The heat arising from a number of gas jets will quickly raise the temperature of a room, and unconsciously people rely upon that means of heating to some extent. Very little warmth, however, is produced by the electric light, and when a man reads by an incandescent light he at times finds himself becoming chilly, and wonders why it is. Too hot during the day and too cold at night are conditions which should be avoided.
