A life history study of the yellow throat
R. E. Stewart
1953, The Wilson Bulletin (65) 99-115
Investigations concerning the life history of the Yellow-throat were made in southern Michigan during the spring and summer of 1938. Supplementary information was also obtained at Arlington, Virginia, in 1940 and at the Patuxent Research Refuge, Maryland, in 1947.....Resident males established territories almost immediately upon arrival in spring. In southern...

Relationship between chemical structure and rat repellency
E. Bellack, J.B. DeWitt, R. Treichler
1953, National Research Council, Chemical-Biological Coordination Center Review (No. 5) 48-156
Repellent activity is defined as the activity of a compound in preventing consumption of, or gnawing attacks upon, foodstuffs or articles containing or treated with the candidate substance. Data are presented on repellency indices of 2700 compounds, and it is shown that repellency is associated with specific functional groups attached...

1953, Journal of the American Pharmaceutical Association (42) 695-697
Data are presented on methods of preparation, chemical and physical characteristics, toxicity, and repellency to rodents of complexes of symmetrical trinitrobenzene with various aromatic amines. When applied in suitable carriers or incorporated in plastic films, members of this series of materials were shown to offer significant increases in time required...
