The wts. of 19 organs in 52 adult male cats and 20 organs in an equal number of adult 9 cats, were correlated with body wt. and with body length. The avg. of these correlations is higher in the malemale, and is higher with body wt. than with body length. The percentage differences range from 12-14%. The individual correlations range from a maximum of 0.978 to a minimum of 0.149. All of the correlations are positive but 22 (9 male and 13 female ) are so low that they are not significant. Each organ or system was correlated with every other organ and for these inter-organ relationships, the avg. of all 190 correlations for the malemale is 0.450 and the similar avg. for the 171 male correlations is 0.546. The avg. of the correlations is 21% higher in the malemale. The wts. of the musculature, integument, heart and kidneys have high correlations with body wt., body length, and with most organs. Low correlations with body wt., body length, and with many of the other organs are found for the hypophysis (with the lowest avg.), brain, spleen, digestive tube length (the only linear measurement) and the pancreas. This last group has avg. interorgan correlations below 0.5. The lowest avg. is that of the hypophysis with the other organs and it is but 0.177. Organs having the lowest coefficients of variability have the lowest coefficients of correlation with the body wt.
