✦ Synopsis
Examining the weight gains of mice in selected and nonselected lines maintained on a low (10%) and high (20%) protein diet, and of their "crossbreds", it was ascertained that the highest values occurred in selected lines maintained on a high protein level and the lowest in "crossbreds".Analysing the enzyme activity - aldolase, aminotransferase AspAT and AlAT - in the liver of these animals, it was observed that selected mice maintained on either of the protein levels demonstrated usually values significantly lower than for the nonselected ones.

Ten adult western gulls (Larus occidentalis) ranging in weight from 761-1,004 gm were studied. The gulls were fed 3% NaCl in their drinking water. They were killed by decapitation, and the salt glands, weighing 0.51-0.78 gm were cooled, homogenized in 0.14 M KCI, centrifuged at 0 4 °C at 20,000 X G
Body composition was studied in three lines of mice, one selected for high (H) and one for low (L) 8 week weight, and one maintained as an unselected control (C). After 25 generations 8 week weights were 41.2g, 30.6 g and 20.5g for the H, C and L lines. Mice were sampled from the lines and analysed
