Reminded me of experiments by Professor of Ophthalmology H. Knapp, who injected cocaine into the nose, mouth, urethra, and... um, “For the sake of completeness I injected cocaine also into the rectum. The sensibility, which was not great anyhow, was reduced."
ALT Photo of a book, “Cocaine and its use in ophthalmic and general surgery” by H. Knapp, Professor of Ophthalmology at the University of the City of New York; G.P. Putnam's Sons, 1885.
Two fingertips are at the bottom of the photo, holding the page.

“6. The rectum. - for the sake of completeness I injected cocaine also into the rectum. The sensibility, which was not great anyhow, was reduced.
I have taken the liberty to reprint the above experiments from the Medical Record (Oct. 25th), because some of them were new -e.g., those on the urethra, the rectum, and the upper nasal passages.
The remainder of my paper contains the description of the application of cocaine in nine patients: squint, foreign body, pterygium, cataract-extraction, tumor sacci lacrymalis…“ etc.
