For example, electric current terminals can be provided on the benches, or steam can be laid on for heat experiments, etc., but these refinements and elaborations depend entirely on the requirements in each individual instance. Stools.--It is usual to provide stools for the students to sit upon. These should be strongly framed together, and have a wood seat about 12 in. by 10 in., and 24 in. or 26 in. high. In girls' schools, where the furniture is not treated so roughly as in boys' schools, some slight extra comfort can be given by having low backs to the stools. Windows, etc.--As it is only for a comparatively few experiments that considerable height is required, a lofty room can be hardly said to be necessary. No definite height of so many feet can be given, as it should bear some relation to the class of work to be, done, and also to the size of the room. The minimum height for rooms used for teaching purposes is given for various areas in the Board of Education Rules, and also by the authorities on school-planning. A top-light is not essential. Wall-space, however, as already mentioned, is most useful, not only for cupboards, but also for exercises in mechanics, etc. Hence it may be sometimes advisable to have a skylight, where one is possible, in order to reduce the number of windows otherwise necessary to properly light the room. However, as the physical laboratory is generally on the ground-floor or basement, a top-light is, in many cases, impossible. A south aspect is not advisable, as the laboratory would then become inconveniently hot in summer. One advantage, however, of windows in a south wall is that an outside mirror or ...
