Abstract
Four mongrel dogs were examined for the density of toruli tractiles with the skin and stained with methylene-blue. Each torulus tactilis was located with a loupe (x5-12)and marked with white lacquer. The distribution of toruli tactiles was estimated from the mean per two-cm square in different parts of the body surface. The results obtained were as follows. The mean per two-cm square was approximately 10-13 in a female specimen, and approximately 6-9 in male specimens. The density of toruli tactiles was thigh in the temporal and buccal areas, on the back of the trunk, on the lateral surface of the forearms, in the gluteal area, and on the lateral surfaces of the thigh and leg. It was low or very close to zero on the face, ears, axial, medial surface of the plica lateris, external genitals, palms and soles.
