To John Innes1 [1848?]2
My dear Mr Innes
I am extremely sorry to hear of your toothache.— You must not put, I think more than one drop of Chloroform on the tooth..—3 I send Tincture of Arnica4 which smarts the skin (deadly Poison) to put outside.— Mrs Darwin finds hot fomentations do best.— Many find cold water applications best.—
I have found two or three drops of Alum & Swt Spirits of Nitre5 (in bottle with a label) sometimes do my teeth great good. I was not in when your note came
Yours | C. Darwin
I send my bottles which you can return afterwards
I send Creosote,6 some find a drop of this do much good
