Abstract

Royal Victoria Hospital and Queen's University, Belfast, Northern Ireland. between the pH of the skin surface and age, during the tirst week of life, has recently been demonstrated by Behrendt and Green (1958). They made pH determinations at three body sites, shoulder, axilla and abdomen, by a colorimetric method (Bernstein and Herrman, 1942), on some two hundred children who had no skin disorders. They concluded, from comparisons between groups of children of different ages, that during the first tw^o days of hfe about fifty per cent, of infants have " abnormally alkaline" reactions although later this proportion decreases so that by the end of the first week of life most infants have a " normally acid skin pH ". Their basic data were presented in the form of a scattergram showing the frequency distribution of all pH determinations made on children of specified ages. From this it was obvious that there was a preponderance of determinations of 6-0 pH imits or more, with many over 7-0 pH units, on the first day of life. Moreover much of the implied fall in pH during the first week of life occurred during the first three days. Determinations repeated daily on
