PROFESSOR KARL PEARSOK, MATHEMATICAL 
Two homogeneous series of neolithic bones ore given by M. Manouvrier in a paper 
entitled; “Etude des Cranes et Ossements humains recueillis dans la Sepulture 
Neolithique dite la Cave aux Fees, a Brueil,”'" and deserve separate consideration.

The corresponding mean values given by M. Manouvrier are : 161 ’2, 163’8, 150'2 
and 154.’3, of which only the last diverges sensibly from mine.t I should be inclined 
to omit the results obtained from [d) as excessive, only the larger radii surviving. 
To do so woidd not much alter my means, based on ten results, although it would 
more sensibly modify M. Manouvrier’s. 
The sexual ratios for the two groups are :— 
* “ Memoires de la Societe des Sciences naturelles ... de la Crease,” 2® Serie, vol. 3, 1894 
(2'= Bulletin). 
t Tlie agreement is surprising, considering that M. Manouvrier -worked only from half my data, and 
allowed very differently for the drying of the bones.
