Agree, Lydart.
In 1849, all medical terms were in Latin, it wasn't someone trying to be smart, or look good. The reason they used those terms then, is the same reason we do today, that's what "it' was called! Today, they do try to make it a bit easier for people to understand what's happening to them. It's called "informed consent", and the legal eagles are quite picky about it, but way- back- then, medicos were such superior beings, the patient wasn't told anything.
