My dear M^rs. Dowie

I was very glad to receive your last note; but alas all is of no use! The point of interest is whether additional digits possess a power of regrowth which ordinary digits or bones do not possess.²

Now Sir J. Paget has quite convinced me that the degree of regrowth observed in the case in question is nothing very unusual with bones amputated during a very early age. I must alter what I have published & confess to error, which is an unpleasant operation; but it is ten times worse to think, that had it not been primarily through your very great kindness, & secondarily through Sir J. Paget, I sh^d. have gone on republishing & confirming an error.³

Therefore once again allow me to thank you cordially for your assistance, & believe me | Dear M^rs. Dowie | Yours faithfully & obliged | Charles Darwin
