    Always lean well back when reading, and hold tlic book up, as shown in the engraving (Fig. 5). Do not lean forward and face the light, as in Fig. 6. Never read by firelight, in the position shown in Fig. 7. Myopia, or short-sight, is often produced, particularly in young people, by reading in an imperfect light. Never read when lying down in bed; or if, owing to Fig. 7.—Reading by firelight. illness, you feel you must do so, then do not hold the book up over your face, but place it on the pillow, and read with your face downward and the back of your head to the light. If you have weak eyes, never sleep with the bed in such a position that your eyes face a window. Turn the side of the bed, instead of the foot, towards the window, and lie on your side with your face turned away from the light.
