emission, The observations were made with an interferometer
consisting of two ideatical broadside arrays, each consinting of
four whole-wave dipoles, on an E--W bescline of 16 wavelengths.
The event characteristics are tabulated. A total of 17 events out
of 43 observed during the period November 5, 1966 to March 4,
1967 contained evidence of continuum emission. That this effect

(Univ,

Nature (London) 218: 461-2(Nov. 4,

The result of the studies by Longair and Scheuer (Nature 215:

919 (1967}} concerning the possible cor. elation between optical and
radio intensities and red shifte in quasare are discussed. These
authors found that correlation dlasppeared when the effects of rela-

tivietic time dilation were eliminaten An exp‘anation of this disappearance is offered, based on absorption by galaxica. The obeerved

Doppler effect in the absorption lines will correspond not to the
Tecearion velocity of the source, but to that of au iatervening galary. (UD

A search was made for extragalactic objects among blue slara

in high galactic latiudes, Spectra of Tonantzintla objects 256,
259, 361, 262, 264, 266, 186, 811, 622, and 317 were obtained with

an image tube and'a grating spectrograph at the Cassegrain focus

of the 128-cm reflector. Except for Tom 356, none of the objects

exhibits emission lines. A apectrophotometric study was made of

the quasi-stellar galaxy Tom 256, discovered by Sandage. The

physical parameters of the gapeous envelope are derived from

ths forbiddem-line ineneities. The eimation is found to be similar
