"No, Doctor, what is it?"

"It is a very small camera which takes pictures one-half inch by
seven-eighths. I had several opportunities to use it. I wasn't sure
that it would work on such short waves, but it did. When Saranoff
tries to return to this country, he will find that every immigration
inspector and every member of the border patrol has an excellent
likeness of him. That may hinder his entrance into the country for a
little while."

A CLASSIFICATION OF THE UNIVERSE

A classification of everything in the universe, from the smallest
thing yet measured, the electron, less than a millionth of a millionth
of an inch in extent, to the biggest, a star system of a thousand
million trillion miles, was described recently by Prof. Harlow Shapley
of Harvard in a lecture at the commerce center of the College of the
City of New York.

Looking forward to a time when man will be able to measure even
smaller things than the electron and larger than the greatest star
system, Prof. Shapley explained that he had left the classification
"open at both ends."

Man, Prof. Shapley said, occupies a very small place in all this
system, although, beside an electron or an atom, he is not so
negligible, at that.

"The survey," it was explained, "aims toward giving perspective. It
gives a sane and modest view of man's place in the scheme.

"The significance of the classification lies in the skeleton which is
afforded all science to bring some measure of order out of the world's
present chaotic knowledge of the systems of various kinds.

"All systems find a place in this synthesis--atoms, comets and
galaxies; man, radiation and the space-time complex. When looked at in
this objective way, human beings, and all associated terrestrial
organisms, appear only parenthetically in one of the subdivisions of
the class of colloidal aggregates."

Prof. Shapley discussed the concept of the cosmoplasma.

"This," it was explained, "is at once the most mysterious and
fundamental part of the universe, and only recently has come under
direct experimental study. In brief, it is the substratum of materials
throughout the universe, between planets, stars and the galaxies.

"It has no obvious systematic organization. Hence it includes such
diverse constituents as the high speed shooting stars, interstellar
calcium gas and radiation itself.

"Though no one has even seen an electron, the smallest thing included
in the classification, the
