Outdoor Solarium
Indoors it is easy to protect the head by simply lying so that it is in the shade of the window-casing and wall. Out¬doors it may be necessary to use a hat or a parasol. In the s enclosures one may lie with the head in the shade of a wall, or a projection may be built or canvas stretched outward from the south wall for use during the time when the sun is fairly well overhead.
