Observations made just now regarding the identity of the measurements 
of Lapland and Massachusetts skulls may be here repeated respecting meas- 
urements of Asiatic, European, and American skins: there are discrepancies, 
but only those of individual variability. 
The distance from nose to eye averages half an inch; from nose to ear, 
about nine-tenths; the length of the head about an inch. The average 
length of the body we cannot make out precisely, as all our specimens are 
dried skins, and many of them stretched or otherwise distorted. Doubtless 
the average derivable from the table, as the figures stand, is a little too high. 
We doubt that any one of the specimens exceeded 3.75 in life, and think 
that few touch this dimension, which we are inclined to fix as about the 
normal maximum; the average is probably just about 3.33, while the normal 
minimum of adults may be a trifle under 3.00. The tail-vertebrae run between 
0.80 and 1.25, with an average of hard upon 1.10; the pencil of hairs at the 
end is the fullest and longest of any North American representative of the 
subfamily, a Lemming hardly excepted. It is rarely under a third of an 
inch, averages upward of four-tenths, and sometimes reaches the half-inch. 
The tail to end of hairs averages close upon 1.50. The palms are within an 
inappreciable fraction of a third of an inch, while the soles correspondingly 
bear upon 0.70, with two-thirds and three-fourths as apparently minima and 
maxima. The ears run between barely over a third to little more than halt 
an inch, averaging nearer the latter dimension.
