The carpopodite correlations in Table III are generally lower than either the meripodite 

 or propodite correlations of tables II and IV. In table III the mean coefficient for car- 

 popodite with carpopodite is .8858 ± .0054. For non-homologous joints from the same 

 table the mean coefficient is .9075 ± .0073. The difference between the two means is 

 then .0217^^.0079, the non-homologous joints showing the higher correlation.

Finally in Table IV. we have the propodite correlations alone. Here the mean coeffi- 

 cient for propodite with propodite correlation is .9551=!=. 0036. For the non-homologous 

 joints in the same table the mean coefficient is .9317±.0017. The difference between 

 the two is .0234^.0040 in favor of homologous joints. 



What was said above regarding the reasons for the considerable difference between 

 homologous and non-homologous joints also applies here. The influence of the low car- 

 popodite correlations is not equally distributed in the two halves of the table. In order 

 to indicate to what an extent these carpopodite correlations influence the results in Tables 

 II. and IV. the following tables (V. and VI.) have been proposed in which meripodite and 

 propodite correlations are considered alone. Tables V. and VI. are to be regarded as 

 supplements to II. and IV. respectively.
