Ten-micron radiometry of 24 asteroids, 22 of which have not previously had their diameters and albedos determined, is presented. The magnitudes of the objects ranged from -0.35 to +5.35 and 13 of them had diameters smaller than 100 km. They ranged in albedo from 0.024 to 0.28, and the 22 previously unstudied objects included 10 C asteroids, seven S asteroids, three U asteroids, and two unknown. In the diameter-albedo plane, ten of the asteroids studied clustered near albedo 0.03 and diameter 100-200 km, in a region previously occupied by only seven asteroids but where Chapman et al. (1975) predicted many objects would be identified upon sampling those fainter than V equals about 12. The new data suggest that there are substantial numbers of S asteroids with diameter less than 100 km in the inner part of the belt.
