The article presents an alphabetical list of abstracts and titles of abstracts submitted for papers presented at meetings of the American Statistical Association and Biometric Society in Washington D.C., in December 1967. The abstract "Indians and Smudges on the Census Schedule," by Donald S. Akers and Elizabeth A. Larmon, is an explanation of how certain anomalies in the reported characteristics of American Indians in the 1960 Census are to be explained by systematic smudging of the census schedules. The abstract "Input-Output and the Economy," by Clopper Almon explains that input-output and regression analysis were once considered rival tools for analysis of the economy. In those days, the constancy of the coefficients seemed a crucial issue in deciding whether or not to use input-output. Today, thanks to the progress in computer hardware and model building technique, regression analysis and input-output complement one another and the constancy of coefficients need be assumed only where we know of no better assumption.
