—Bagg1 reported the results of experimental studies dealing with the effect of roentgen and radium treatment for certain congenital hereditary abnormalities of the genito-urinary organs that were found in laboratory animals. His data have been collected during the last six years and are based on records of 5,600 necropsies, especial attention having been given to selective breeding for renal defects. One thousand and fifty-seven animals had defects of the kidney. There were 1,000 animals, 519 males and 481 females, with one or both kidneys missing. One kidney was absent in 630 animals, and both kidneys were absent in 334 animals. Twenty-five animals had a solitary kidney which was reduced in size. Thirty-five animals had one hydronephrotic and one normal kidney. There were 11 animals with one hydronephrotic kidney; the other was not present.
