A double quasistellar object
It is reported that 1548+115a is also a QSO. Spectral information is provided for 1548+115b and 1548+115a, giving attention to the very different redshifts of the objects. The observations reported are believed to add support to noncosmological theories of redshifts. Such theories will receive additional support if an interaction between the two components of a close pair can be shown.

Discrepant redshifts of QSOs in clusters of galaxies and a close QSO pair
The question is investigated whether QSO redshifts are cosmological in origin, taking into account the possibility that QSOs may be more local objects. A search is made for situations in which more than one blue stellar object (BSO) lay close to a radio position selected from the 4C catalog. It is found that in all four examples studied the radio emission arises in the QSO and not the galaxies or cluster of galaxies.

A spectroscopic survey of 92 QSO candidates
Spectra obtained for 92 QSO candidates selected mostly on the basis of their proximity to radio-source positions are presented. Thirty-two were classified as QSOs on the basis of broad emission lines and stellar appearance, whereas redshifts were determined in 14 instances.

The absorption line spectrum of 1331 + 170.
The absorption-rich optical and near-infrared spectrum of the quasi-stellar object 1331 + 170 is analyzed. The emission-line redshift is about 2.08, and at least three absorption systems are shown to be present; the absorption redshifts are 1.7755, 1.7851, and 1.9637. We conclude that the absorbing material giving rise to the three systems is intrinsic to the QSO despite the high velocity difference between emission and absorption systems and the low velocity dispersion within each absorption system.

Redshift of OQ172.
Comments on a recently discovered second QSO with a redshift greater than 3. From a study of a composite spectrum of OQ172 formed by adding data from spectra obtained on different nights two strong emission features near 5540 and 7015 A are noted and are identified with Lyman alpha 1216 A and CIV 1549 A. The measured wavelength of the emission peaks corresponds to a redshift of 3.56 for Lyman alpha and 3.53 for CIV. It is concluded that the emission line redshift of OQ172 is near 3.53.
