“…D.D.T. has been shown to be toxic to a variety of mammals, including rabbits, guinea-pigs, rats (Draize, Nelson, and Calvery, 1944;Smith and Stohlman, 1944;Cameron and Burgess, 1945), cows, sheep, horses (Draize et al, 1944), and cats (Lillie and Smith, 1944). The main pathological features seem to be liver damage of varying degree sometimes reaching the stage of necrosis, loss of weight, anorexia, mild anaemia with a reduction of the mean corpuscular haemoglobin, polymorphonuclear leucocytosis, and damage to the central nervous system, causing excitability, instability, tremors, and muscular weakness (Cameron and Burgess, 1945).…”
