Cambridge University Library (Add 4251/330)
Summary:

Thanks for JG’s book [An introduction to the Trochilidae, or family of humming-birds (1861)], which he has read carefully. Hopes someday to use the information on the close alliance of species in large genera.

CD repudiates hybridity of birds in nature.

Intends to extract the cases of "races" or doubtful species. They show that "determination of species is not a simple affair".
