1t has been proven by trial that
cement mortar which has been mixed

water sets quickly, but at the end Of
two years is only about half as hard as

"A recent assertion that water color
paintings are affected injuriously by
constant proximity to electric lights,
the more delicate pigments fading in
consequence, does not seem to be borne
out by the facts. AS disintegrating
force, daylight is known to be far more
powerful than electric light of equal in-
tensitY. The latter too, as is well
known, is less active agent than day
