32 Encephalic Anatomy of the Races 
presents a series of drawings showing all possible views, made directly 
from the specimens by himself, with the incidental aid of a stereograph. 
The nomenclature here employed is that proposed largely by Wilder, 
and accepted by the Association of American Anatomists and the 
American Neurological Association; a nomenclature unquestionably 
superior to that of the BN A in consistency, clearness and conciseness. 
The writer prefers the angloparonym “gyre” (plural “ gyres”) to the 
Latin “ gyrus” and “ gyri.” All anfractuosities of the surface are desig- 
nated “fissures,” the term “sulcus” being abandoned entirely. 
The fissures and gyres have been uniformly designated in the figures 
by abbreviations (see list at the end of this article). Where the length 
of fissures is given, the measurements were made by a moistened string 
laid along the course of the fissure. 
The comparative dimensions of the cerebral parts, as well as the 
conformation of the cerebellum, pons and oblongata will be discussed in 
the sequel of this series.

1. BRAIN oF “ ATANA.” 
(See Figures 1 to 6.) 
Our first specimen is that of an adult female, “ Atana,” the wife of 
“ Nooktah.” Her age is in the neighborhood of fifty-five years, and 
she is described as having been unusually intelligent, as may be judged 
from the fact that she was the “ medicine-woman” of her tribe. She 
died of tuberculosis on March 15, 1898, at 2 p. m., and her viscera were 
removed at 4.30 p. m. of the same day. Unfortunately, the brain was 
not weighed while fresh. It was placed in a mixture of formal and 
alcohol. Its weight on May 25, 1901 (i. e. after over three years), was 
as follows: 
Left hemicerebrum, 446 grammes; right hemicerebrum, 439 grammes: 
eerebellum, pons and oblongata, 163 grammes. Total, 1048 grammes. 
It may be assumed that the original weight was in the neighborhood 
py 5 Fe) to} 
of 1575 grammes. 
THE CEREBRUM. 
The cerebrum is quite firm in the deeper parts, but the cortex is ex- 
ceedingly soft and does not admit of much handling without damage 
to the surface. 
In general, the cerebrum is very well developed. Fissuration is, if 
anything, rather superior in complexity to that shown by average Euro- 
pean brains. This complexity is a trifle more marked upon the left
