INTRODUCTION
The neonatal body weight dataset comprises two tables. The first table provides numerical data for total neonatal body weight in 416 rows (species), where litter size may be one or greater than one. The second table provides 11 references from which the numerical data were taken.
Note that the numerical table has 9 columns. Observe that total neonatal weight is computed as the product of neonatal weight and litter size. About half of the records in the numerical database were taken from J.F. Eisenberg (1981).  Data for neonatal weight, where litter size is restricted to one, are given in the next set of tables.
