'Oology a Science' 



To the Editor of Bird-Lore: 



The recent discussion of this subject in Bird-Lore and 'The Condor' 

 has been one of considerable interest, but in spite of the various views given 

 it still seems that the crux of the question has been passed unnoticed. 

 In the first place, it must be admitted that oology is not embryology and 

 that, therefore, it is more or less unreasonable to discard the former because 

 it has given no results to the latter branch of science. Oology, even at its 

 best, has nothing to do with the development or structure of the 

 embryo, except in so far as it affects the removal of the same from the 

 shell. Therefore, oology, as oology, should not be tried on its merits as 

 embryology, though it is difficult to see how any thorough naturalist can be 

 unfamiliar with the great names cited in former letters on this subject. 



Mr. Lucas has mentioned several cases where external ovarian fea- 

 tures have yielded greater or lesser results in capable hands, and a few more 

 might be cited that have shown confirmatory evidence of taxonomical 

 relationships, but here is the point — are these few and isolated results 

 enough and sufficient to dignify the subject as a special 'ology'? Is there a 

 series of facts in nature, however commonplace they may be, that, with the 

 same amount of work as has been expended upon egg-shells, would 

 not have yielded equal if not greater results ? Do these meager results war- 

 rant us classing egg-shell study, as a whole, as scientific? 



On one point all authorities seem agreed, that nest -hunting does afford
