parison in utilising as its standard a figure whose magnitude is dependent 
upon the sum of a series of variables obscures the true value of the figures. 
Unfortunately, the observer (1) from whose writings the absolute measure- 
ments are taken has not provided any measurements more suitable.

When compared with Tables XX. and XXV., the results of these three 
observations support in a most remarkable manner the findings with regard 
to the interproportions of the limb segments of subject A 9. Unfortunately 
they can give no further help.
