My dear Sir

I return you many thanks for your two kind letters— I shall have no hesitation in using your testimonial   I feel that my Essays having obtained your favourable opinion is a real honour & am confident that it will be so considered by all scientific persons—²

Unless the physicians have quite lost their ancient reputation they ought not to be troubled by any considerations about “unorthodoxy” nor do I suppose they will unless indeed it comes before them in the shape of a proclivity to homeopathy—³

You must excuse my assuring you that I should no more think of printing half your testimonial and omitting the rest than I should of perpetrating any other piece of dishonesty—

I am | very truly yours | Gilbert. W. Child

C. Darwin Esq.
