Schedule A: Results of research looking at the ability of an animal to kill ticks place upon it with the number of dippings the animal receives Schedule B: A chart showing that the length of time elapsing since the last dipping determines the ability of an habituated animal to kill ticks which may become attached to it; Schedule C: A chart with observations to show that in habituated animals the effect on ticks of a given dipping is more rapid then in non-habituated animals; Schedule D: A chart of observations showing the retardation of the infective process in the habituated animal; Schedule E: Estimations of the amount of Arsenic retained by the hair and hide of animals for varying periods after dipping; Schedule F: A chart to show the elimination of arsenic by the kidneys at varying periods after dipping.15 pages : 4 chartsen© Dept. of Agriculture, South africa (original). © University of Pretoria.
