has ten wave-lengths ranging from 3,ooo to 5,ooo ~.U. that are not in the spectrum of nitrogen nor in that of atomic oxygen with perhaps one exception.

The famous green line, 5,577 A.U., long defied identification.

At last in I925 McLennan and Shrum showed it to be emitted by atomic oxygen. A study was made of the intensity of this line in the spectrum of the night sky. It was found that after sunset the intensity of the green light from the zenith increased until a maximum was attained about one and a half hours after midnight. From this thne onwards until sunrise there was a decrease. G. F. S.

Assuming, that the sources of scattering act independently in the two thin coaxial metallic wires, and introducing the mean free path describing the Fuchs-Sondheimer effect, an apparent size effect is then defined. The aim of this paper is to show that the size effects in the thin coaxial metallic
