With regard to the computation of r^, it will be seen from example appended to 
Table A that the amount of labour involved in dealing even with a 3 x 3 table is 
considerable and will rapidly increase with the number of cells, and it is very 
desirable that some short method of approximating to the weights (C's) of the r's 
be devised. For the present it may be of interest to give here the C's for the various 
tables used.

The case of Table G, with negative weight for 7^2. ^^^^ ^^21 is suggestive and needs 
further study. The table has the characteristic that the mean is in and the 
marginal frequencies are decreasing in magnitude and nearly equal in both sets of 
categories. The table "Pairs of brothers" which is accompanied by similar weights 
is taken from Biometriha, vol. iii, 1904, p. 182, and is given below. It compares the 
athletic capacities of pairs of brothers.
