But here let repeat the warning suggested
by physician in THE TRIBUNE of yesterdays
Everything tending to strain fatigue either the eyes
themselves the adjacent muscles, should be avoided
Using an Opera-g is less irritating the than
spy-gass because while double the light is received and
both eyes instead OF one are employed the muscles sur

image is by making pin-hole in large card and so
holding 1t that the suns rays shall shine through the
