LIGHT

is of great value to bealth. It kills germs, stimulates growth, and promotes a cheery frame of mind. To keep the blinds always down in order to protect the ue from fading is not the best policy in the long run. Light is used in the treatment of certain diseases. Finsen, of Copenhagen, demonstrated that sun-light pa ed through green screens, to remove most of its heat, and focus<ed on skin affected with lupus had a curative effect. The treatment is now widely practised, its introduction into this country being largely due to Queen Alexandra. Instead of sunlight electric light is utilised. Sun-baths are slso used for many conditions. They consist of basking in the sun whilst lightly clad. [tis doubtful if the sun bath merits all that is claimed for it. [Refer to Lapua.) [s. 382]
