measurement is given upon a skull in which it is known that the part does 
not exist, such measurement has been made from the reconstruction of 
either Schwalbe or Klaatsch. 
The results attained by this comparison are first of all set forth in 
Tables I. to XXVII. inclusive, where each table records in a progressive 
arithmetical series the results of the comparisons for each one of the 
twenty-seven observations made by us upon the Tasmanian crania. Unless 
specially mentioned to the contrary, the results are set forth in a pro- 
gressive series from the lowest figure to the highest, or from the highest 
to the lowest, according to the scale of evolution; and as it has been 
impossible for us to obtain all the required data in the objects selected by 
us for comparison, we have thought it advisable to show in each table 
not only those with which the comparison is made, but also those which 
were excluded from the comparison.

On the assumption that marked length of skull with dolichocephaly 
is a primitive characteristic, the figures in this table are arranged in an 
ascending scale from the nearest anthropoid to the maximum, and there- 
after in a diminishing scale. As such an arrangement is purely 
hypothetical, this table is very properly omitted from the final results 
obtained in Mr Cross’s paper which follows.
