Using data from the Ontario Longitudinal Study of Aging, the associations of remaining in good self-rated health with various independent variables are examined. Indicators of an "advantaged" socioeconomic status (e.g., relatively high levels of income and education), not smoking, and moderate alcohol use are associated with remaining in good health. The strongest association is observed between a life satisfaction index and remaining in good health, and different explanations are suggested for this finding. Comparisons with the previously reported associations of these same independent variables with mortality show different relationships for the two end points. For example, the associations of several indicators of social relationships with maintaining good self-rated health are not significant, although a strong relationship between social isolation and mortality has been reported. These differences can be explained by assuming that the relationships with the maintenance of good self-rated health can be affected by differential mortality rates.

A spectral analysis of benzene derivatives is extended to substituted phenols. The discussion emphasizes hydrogen bonding and steric effects which occur in phenols. Some of the phenolic absorption bands are ascribed to locally excited states.

An examination has been made of the carbonyl stretching bands in the infrared spectra of acetophenone derivatives substituted in the aromatic nucleus. The positions, integrated absorption intensities, and widths of the bands have been measured in carbon tetrachloride solution. The variation of these quantities is discussed in relation to the nature and position of the substituent group.
