If sunshine is employed, a sheet of blue glass should be used as a screen to defend the eyes from too much glare, because this glass does not materially weaken the power of the chemical rays to affect the paper.

He conceived, that in the anxiety to obtain a light roadway, mathematicians and even practical engineers, had overlooked the fact, that when lightness induced flexibility, and consequently motion, the force of momentum was brought into action, and its amount defied calculation. On the llth of October, 1838,...
