Preliminary studies1 demonstrated the constancy of basal measurements of the insensible perspiration in infants by the method of weighing under standard conditions. This demonstration of constancy and the absence of published basal figures led to the present study of a comparatively large and representative group of infants in an attempt to establish basal standards and normal limits of variation for this measurement in these subjects analogous to the well known standards at present available for their basal metabolism.
The composition of insensible perspiration,2 the apparatus and technic of measurements and the sources of error were fully considered in the previous paper.1 That study established the reliability of measurements with the balance and showed that with careful technic the experimental error of the method was probably less than 10 per cent.
The standard conditions that gave basal measurements in the previous study were employed in the present investigation.
