Though our present paper was not aimed at a discussion of the problems of control of the flies vexing cattle and transmissing their diseases, we can risk a statement based on the foregoing: a control of Musca autumnalis cannot be satisfactory by spraying treatments of cattle. Sprayings can kill at most the minute ratios of the imago populations calculated above. In addition, the relation of the killer effect and the contact repellent effect of the pirethroids - which are mostly used for these sprayings - has not been cleared expe rimant ally yet, and, in all probability, these two effects cammot be separated even theoratically. That Is, In the period when any of these compounds is on cattle in a killing dose, the M. autumnalis imagos will perish, later they will more or less be poisoned, respectively, the susceptible individuals perish, which will result Inevitably and very
