Several previous investigators have shown that the adrenal glands are much larger in wild Norway rats than in domesticated Norway rats. In order to determine whether such variations are peculiar to rats, or represent a generalization in nature, the adrenals were examined in other species of rodents. For this purpose the adrenals of white-feeted mice(Peromyscus-leucopus noveboracensis), house mice(Mus musculus domesticus), and Garworth Farms - W albino mice(Mus musculus domesticus) were compared. Furthermore, an attempt was made to determine the effect on adrenal structure when wild mice were confined in captivity or bred in captivity. Experimental procedures: All wild mice were caught in live traps either in homes or in and around the wooded areas of Metropolitan Boston. These traps were set in the evening and picked up the following morning. [TRUNCATED]
