Abstract

It has been shown previously that the weight (W) of an entire litter of newborn young of multiparous mammals is proportional to the number (N) in the litter. This proportionality may be expressed by the empirical equation

K

W=N+C

where K is assumed to have the properties of a partition coefficient and expresses the manner in which a limited nutritional supply is shared by the members oi the litter. This relationship also holds for human multipara, though it is modified by the inability of the human mother to increase the nutritional level to the same extent as other species we have investigated.
