Charles Martins of Montpellier will collect the varieties of silkworm for CD.
QdeB is battling with the polygenists in the Société d’Anthropologie.
Continues to support, in debates at the Société d’Anthropologie, the view that variability of animals and anatomical modifications are produced by environment. Wishes to use CD’s niata cattle example from Journal of researches [2d ed., pp. 145–6].
Spoke on Moulin-Quignon Jaw before Académie des Sciences.
Thanks CD for photograph [of Niata skull].
Controversy on species fixity [at Société d’Anthropologie].
Sends photographs of Mouin-Quignon Jaw.
The niata is a very good case because the race is well established and must originate in South America. There is a description of the head by [Richard] Owen in the Descriptive catalogue of the osteological collection of the College of Surgeons.
Has observed modifications in the skeletons of rabbits, ducks, poultry, and pigeons. There is an extract about modifications in pigeons in the first chapter of Origin. Encloses a woodcut of crested or polish fowls; there is a change in the brain as well as in the exterior bones.
Is sending photographs of the niata skull [requested in 4082]. W. H. Flower reports that he could have a cast made for £3.3s.0d.
Specimens obtained from Charles Martins will be most interesting.
