INTRODUCTION

The dataset  for red blood  cell volume, measured in cubic microns, is presented in two files. The first file summarizes the numerical data in tabular form in 109 rows (species) and 6 columns. 
Observe that all the body weights are taken from the standardized body weight table. (see The Design of Mammals: A Scaling Approach (2015), Cambridge University Press, Chapter 4).  The second file gives the single source from which the red blood cell volume data are taken.
