Searching Project Gutenberg for something that now escapes me, I stumbled across this little gem:
ARTS, MANUFACTURES, PROFESSIONS, AND TRADES
Medicine, Pharmacy, Hygiene, and Domestic Economy
by Arnold Cooley and Richard Tuson, as published in 1880
in which we find:
Treatment of persons struck by lightning. In case of any person being struck by lightning, immediately strip the body and throw bucketsful of cold water over it for ten or fifteen minutes; continued frictions and inhalations of the lungs must also be employed, and electricity should be tried if it be possible.Note that last about trying electricity. You know, were I ever struck by lighting back in the mid-to-late 19th century, I think I'd be happier to just die quietly, if that's alright.
I was going to look up a cure for the toothache, but I'm a bit afraid of what I'd find.
