(Livon’), and 63.5 (Dwight). The result is also similar to that obtained 
by Professor Turner, 65.0, on the scapulæ of nine Fuegians. 
he mean infrascapular index of 83.2 does not seem worthy of much 
consideration, from causes which have already been mentioned. Itma 
be noted, however, that according to the table given by Professor Tur- 
ner,’ this index is lower than any yet recorded for any race except the 
Eskimos, Hottentots and Tasmanians. 
CONCLUSIONS. 
From the present inquiry the following conclusions can be made : 
1. There is a marked difference in the size of the scapula in the two 
sexes; this is seen in the dimensions of the glenoid cavity, and in the 
leugth, breadth and,infraspinous length. 
. Lateral variations in the scapuls in linear dimensions are so slight 
and so contradictory as to be explained perhaps as due to an insufficient 
number of observations. The right bone is, however, a trifle larger than 
the left in a small percentage of cases,—this percentage being larger 
than that of the left bone exceeding the right in size. 
3. There is no important difference in the dimensions or indices of 
the scapula between the Kwakiutl and Songish. 
4. There is very little difference in the two indices in the two sexes; 
the female, perhaps, having indices a trifle higher than the male. This 
is in accordance with the results of Livon. Broca, on the other hand, 
considered the male to possess the higher index. 
5. The range of variation for the scapular index is not excessive, and 
there is a certain amount of uniformity in its distribution which makes 
the mean index of value. 
6. The range of variation for the infraspinous index, while not ex- 
tensive, is so evenly distributed as to destroy in part the value of its 
mean ; and so it cannot be considered to have a value equal to that of 
the scapular index as representing the average for Northwest Coast 
Indians—Grorce A. Dorsey, Pu. G., Assistant Curator of Anthro-
