reflected, refracted, tinted with all the rainbow hues, and finally
projected through the clear plate-glass windows of the lantern with all
the force and brilliancy of a hundred rays. If any one cares to
understand more clearly the why and the how, let him either go and see
for himself or read about it in Brande's Encyclopædia. Mysie and the
Baron were content to bask ignorantly in the glittering, ever-changing,
