Note. — Blank spaces indicate that tlie measurement could not be made or, because of distortion while hardening, was not available for 

 the purposes of comparison. The absolute measurements of the brains of the eminent series are often below those determined in tlie brains 

 of the ordinary series for the reason that mo.st of the former were preserved in alcohol or mixtures containing alcohol, and therefore 

 producing more or less shrinkage, while the latter were all preserved in formaldehyde and underwent little or no shrinkage. The figures 

 expressing relativity (in centesimals or percentage) are the most useful for analysis.
