of "316 is higher than we should expect from other work done and this will be 
increased when we can allow for the inheritance between the first finger and the 
other fingers. If we compare the mean of the two forefingers ^29 with that found 
for the grandparental relationship we see that they are almost the same and we 
had supposed from previous work that the grandparental relationship was slightly 
higher. At the same time considering the number of cases and the probable error 
there is really nothing in contradiction with former work in these results. 
We cannot however say the same when we turn to cousins. Inheritance of type 
of finger-print in cousins is significantly lower than in the grandparental or avun- 
cular relationship, a result not confirmed by any other work we have done except 
in the less easily measured characters such as temper. Though the values of the 
coefficients are very low the diagonals are positive and there is no doubt about the 
sign which is an important point to consider when the contingency values, un- 
corrected for grouping, are as small as they are in this table. Further the correction 
for the number of cells leaves ^- positive, but we must admit that we were 
surprised to find such low values and it is difficult to account for them. Family 
schedules accompanied the finger-prints and there seems very little chance that 
there could have been any selection of the cousins considered. When the anthropo- 
metric department at the Galton Laboratory can be fully equipped and opened 
we hope to obtain more extensive finger-print data for the whole hand for 
collaterals and until we have that material we can only give the results we have 
reached on Galton's own data. We have at present no explanation to offer for the 
low values obtained for the resemblance in finger-prints between cousins.
