to do with specimens, now, to which I would not give houseroom in 
my own cabinet. If forced to reduce bulk, owing to limited facilities 
for transportation in the field (as too often happens), throw away ac- 
cording to size, other things being equal. Given only so many cubic 
inches or feet, eliminate the few large birds, which take up the space 
that would contain fifty or a hundred different little ones. Ifyou have 
a fine large bald eagle or pelican, for instance, throw it away first, and 
follow it with your ducks, geese, etc. In this way, the bulk of a large 
miscellaneous collection may be reduced one-half, perhaps, with very 
little depreciation of its actual value. The same principle may be ex- 
tended to other collections in natural history (excepting fossils, which 
are always weighty, if not also bulky); very few bird-skins, indeed, 
being as valuable contributions to science as, for example, a vial of 
miscellaneous insects that occupies no more room may prove to be.

from the text, being sometimes rather linear or oblong, and grayish, 
livid bluish, or evenreddish. I lately found, in a bay-winged bunting, 
only one testis, twice as large as natural to compensate for want of 
the other.
