The series from these dolmens is very small. On the other hand the Guanch 
series are both very complete. The first are drawn from the Musee Broca, and the 
second from the Museum d’Histoire Naturelle (see Rahon, loc. cit., p. 446), both at 
Paris. Although the first series comes from a single locality, and the second from 
several localities, the results are in good agreement. The following statures have 
been found from our formulae ;—

The first point to be noticed about this table is the confidence it inspires in 
formula (k). Whenever the series is in the least extended, formula [k) gives a result 
sensibly identical with the mean of all ten formulae. 
M. Rahon’s means for the eight groups are not very divergent from mine, he 
gives :— 
166-0, 154-8; 165-7, 153-2; 165-3, 154-4; 166-0, 155-4; and 165-9, 154-3. 
He thus does not make quite such a sensible distinction between the Gunnches and 
the Dolmen-builders as my numbers seem to indicate. It is curious that these three 
groups of Dolmen-builders should stand so close together, and also comparatively 
close to the Guanches. The Dolmen-builders must have been as tall as the modern 
French, while the Guanches were probably slightly taller. Both were of greater 
stature than neolithic man in France, approaching more nearly the neolithic man of 
Britain. 
The sexual ratio in the first and third cases cannot be considered of any weight, 
as the female data contain only single individuals.
