THE WEIGHT OF THE BRAIN AND SPINAL CORD. 



97 



again divided into three series according to their stature, 

 thus giving us the figures for the tall, medium, and the 

 short persons. Under each one of the classes thus 

 marked out that is, among people between given ages 

 and of a given stature are recorded the weights of the 

 subdivisions of the encephalon as above named. There 

 is thus obtained an unusually complete presentation of 

 the weight as affected by the most important conditions 

 that modify it. Dr. Marshall's tables were expressed in 

 English weights and measures, but these I have taken 

 the liberty of translating into the metric system, since 

 by far the greatest number of observations on the brain 

 are thus recorded.

AND ITS SUBDIVISIONS IN SANE PERSONS, THE RECORDS 



BEING ARRANGED ACCORDING TO SEX, AGE, STATURE.

a. indicates that a record considered according to age is too 



large, s. indicates that a record considered according to stature 



is too large.
