Orchid anatomy.
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".
Has sent the packet of letters written to Francis Baily to Greenwich, but kept back one or two including the one on the R.S.L. Secretaryship. Is told that James South is now suffering from deafness. Has sent a paper on errors of observation to Cambridge. Comments on this.
