To Lawson Tait 2 March 1876
Summary
Thanks RLT for his letter. CD took much trouble over his two cases [regrowth of amputated supernumerary digits, in Variation] but the evidence was shaky.

To Lawson Tait 25 March [1876]
Summary
RLT’s two articles in Spectator [4 Mar and 25 Mar 1876] greatly honour CD.
Tait has made a good point about "Survival of the Fittest".
Dr Rudinger’s extensive inquiries show that all eminent German surgeons are unanimous about non-growth of extra digit after amputation.
J. Kollmann has written regretting CD has given up atavism and extra digits [in 2d ed. of Variation]; gives new evidence of a rudimentary sixth digit in batrachians.

To Lawson Tait 28 March 1876
Summary
James Paget’s scepticism about regrowth of digits. Suggests RLT experiment with amputation of digits, both extra and normal, of kittens and fowls. Fears they will fail to regrow, but, if regrowth is proved, it will be an important discovery.
