CD has previously received information on colours of greyhounds. Now asks whether breeders rear all puppies, and, if not, do they selectively rear more males or females?
W. J. Beal’s paper ["Phyllotaxis of cones", Am. Nat. 7 (1873): 449–53] shows incompleteness of HA’s theory, but does not invalidate his basic principles on origin of leaf arrangement or the broad applicability of the theory.
Thanks JDH for Asa Gray’s interesting letter.
Would like JDH’s copy of Coral reefs. Needs it for corrections for a new edition. Cannot buy one.
Pleased they will publish a new edition of Coral reefs, and he will soon consider any addenda and write a short preface.
Will return the wood-blocks of Journal of Researches the following week.
Could his copy of Coral Reefs please be returned.
CD is glad Horace has done "pretty well" in his examination.

CD requests WW to ask a large breeder of greyhounds whether the increase in litters requires that some puppies be destroyed. If so, is it sufficient to destroy merely the small and weak? Would this result in more males or females being destroyed?
CD once used the Field to tabulate ratios of female to male births in greyhounds (110: 100).

The coral-reef book has been invaluable [J. D. Dana, Corals and coral islands (1872); used by CD in Coral reefs, 2d ed. (1874)].
