All the abo\'e coefficients of correlation are positive i)i sign and each exceeds 
three times its corresponding jJi'obable error. It will be seen from the above range 
that the differences are suggestive, therefore I am undertaking further investigations 
and hope to give the results shortly. 
Table II, {a) to (q) gives the correlation-tables from which the constants have 
been calculated.
