Morbus

I thought he were took with the Morbus one day, I did with his nasty angle! For “oh dear,” says he, and burst out in a cry, “oh my gut is all got of a tangle!”

Probably no small share of our cholera morbuses, diarrhœas, and dysenteries, have their origin in this source.

Unfortunately, most of the morbi accepted in modern medicine are only taxonomic entities whose causal derivation is merely partially known and therefore polygenic.
