The thickness of the hypodermic fatty layer was measured in 45 infants (20 males, 25 females) . The measurements were taken from 36 different points of the body on the 3rd day and the 6th day after birth. The results were examined for difference in thickness between the 3rd day and the 6th day in both sexes and for the relationship of such difference with : the physiological decrease of body weight of the infants, the thickness of the hypodermic fatty layers of the respective mothers, and the delivery frequency and age of the mothers.<BR>1) The distribution pattern of the thickness of the hypodermic fatty layer in infants was the same as the pattern in older individuals, but the disparities between the thicker parts and the thinner parts were smaller than those of the older subjects.<BR>2) The thickness on the 6th day showed a tendency to be greater than that on the 3rd day in both sexes ; this tendency was more evident in males than in females.<BR>3) Comparing the differences in relation to sex, they tended to be larger in all the anterior parts of the upper extremities, the posterior parts of the upper arm and the anterior trunk around the navel in males, and in the hips and the posterior parts of the lower extremities in females.<BR>4) Thickness increase between the 3rd and 6th days tended to be limited to the anterior surface of the arm for infants gaining 101 to 150 gm., and to be generally distributed throughout all parts of the body for those gaining more than 150 gm.<BR>5) The children of mothers who had thicker hypodermic fatty layers, and were multiparous, and aged, had thicker hypodermic fatty layers than the other children.
