There is ere other way: That is to ga

70. the reader may urge, but you TO
81 TOW told us that IL the waves
light were too small the eye could -!

ded that the Photographic plate co
I'D gee smaller waves than our @
IS. Consequently, in the micro

y use light Of the kind which Is
yisIble to human eyes-the ultra !
