I'm confused.
> That done, the antiseptic was pumped into every one of the innumerable tooth wounds until my arm was so full of the liquid that an injection in one drove it out of another
Isn't antiseptic applied topically not systemically, as they seem to be doing here by injection, and didn't antibiotics get developed later than this? I can't understand what they were injecting him with. Can anyone fill in my gaps, please.
