116 APPENDIX TO MANUAL. 



to do with specimens, now, to which I would not give houseroora 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. If you 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 S9,me 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.

 the skin is still more tender and liable to be torn.

 from the text, being sometimes rather linear or oblong, and grayish, 

 livid bluish, or even reddish. I lately found, in a bay- winged bunting, 

 only one testis, twice as large as natural to compensate for want of 

 the other.
