116 APPENDIX TO MANUAL. 



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. 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 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.

 looked the night-hawks and whippoorwills ( Caprimulgidce) , in which 

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

" 94. Testes vary more in shape and color than may be inferred 

 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.
