Measurements of Cairo-borii Egjjptians 
The results shown in Table V have been compared with the like data for 
European countries, and no serious deviation in the coefficients has been noticed. 
This tends to confirm the statement made above for the head characters.

7. Regression Equations. Considering the significancy of all the coefficients of 
correlation shown above, we may Conclude that the variability between the human 
organs is not chaotic, but governed by very definite laws. We are therefore able 
to predict an unknown measurement in terms of the given length of a known 
organ. 
Table VII results from this investigation. This table shows us how and with 
what accuracy human characters can be calculated one from another. The
