Thanks for information [on regeneration quotation].
The [genealogical] table seems excellent. Would be obliged for any further information about the children of the cousins – the case surprises CD.
Thanks HBD for his note. The analogy of surnames had not occurred to CD – only that of language generally, as shown so well by Lyell. Fears HBD’s argument about progression would not have much weight.
CD thinks HBD’s tables would be a considerable gain because "the importance of hereditary transmission can hardly be exaggerated from every point of view". Makes suggestions.
Asks him to send any remarkable cases of inheritance to him and, as well, any case of regrowth of amputated additional digit.
At CD’s request HBD has traced the quotation; it is on regeneration from Charles White in W. B. Carpenter’s Comparative physiology (1854), p. 480.
Is gratified that CD thinks some of the arguments in his book [Lectures on the germs of disease (1861)] are satisfactory.
Sends CD a form he has devised of a proper genealogical table of three or four generations of the families of medical cases, so that hereditary transmission may be more accurately and fully recorded.
Sends copy of the table, which now embodies CD’s suggestions [see 4117].
Gives instances of persons born with two thumbs and comments on hereditary factor.
Suggests man’s original mode of walking and running is similar to that of quadrupeds.
He also suggests CD answer critics who say no new species has ever been unequivocally traced to its origins, by pointing out that there is no unequivocal account of the origin of surnames.
