(15) The lingula, central lobule, culmen, superior portion of declive, anterior lobules and anteromedial half of simple lobule were severely degenerated, while other lobules were spared excluding moderate degeneration in inferomedian portion of the hemisphere.
(16) Results for 177 mice revealed that many brains had extra sulci present within the central lobe, the culmen, the declive and the uvula, and that patterns within a genetically uniform inbred strain were highly variable.
(17) Growth rates for body weight, culmens, wings, and tarsi of both species on control diets exceeded those on many treatment diets but the differences were less apparent for mallards than for black ducks.
