the event of the twin-sister’s brain being obtainable, the opportunity 
for seeking out evidences of hereditary similarity in the gyral pattern is 
irretrievably lost. “Zakesino,” the twin-sister, is still in New York 
City, and is reported to be advancing rapidly in her school studies. 
An interesting feature of the Eskimo brains so far reported is their 
weight. (See Table I.)

So far as one may venture to express an opinion concerning the 
© weight of the Eskimo brain, it appears safe to say that it is rather above 
the average of the European brain. ‘This is certainly true of the three 
male brains whose actual weight is recorded in the table, and the con- 
clusion is further fortified by the results of the numerous cranial meas- 
urements of the Anthropologists.’ 
Of the female specimens, the brain-weights of “ Avia,” “ Ulrika,” and 
“ Atmahok ” are actual figures; while the fourth, that of the old woman, 
“ Atana,” is estimated from the present weight. The other specimens, 
which had been immersed in a similar fluid for the same length of time, 
lost from 26 to 29 per cent of their original weight. “ Atana’s” brain 
may therefore be assumed to have originally weighed about 1375 
grammes. 
DESCRIPTION OF THE BRAINS. 
The description of the fissures and gyres must necessarily be brief, 
emphasis being laid upon those features which most markedly differen- 
tiate these brains from each other as well as from those of other races, 
European brains in particular. Convinced that figures convey more 
information than words, and that they occupy less space, the writer 
1S8ee Topinard’s “Anthropologie.”
