    of a newborn baby’s blood is a true mirror image of the weight curve : as the weight begins to fall imme¬ diately after birth, the refraction curve rises ; when the weight reaches its minimum, the refraction reaches its maximum ; with increase in weight, the refraction curve falls. Hence the initial loss of weight by the newborn baby is, in part at any rate, due to loss of 1-3490 1-3480 I •3470 1-3460 I •3450 'b 0 o o X to c to -o o I Age in days Fig. 1.—Relation between weight of body and refractive index of blood in a newborn baby. water by the tissues which they make up by absorbing water from the blood (see fig. 1). Similar studies, as well as the actual estimation of the blood-volume by means of the vital red method, have confirmed the theoretical expectation that changes in blood-volume occur whenever there is lack of balance between the amount of water taken into the body and that eliminated from it. When the balance is positive, i.e., on the side of the intake,
