Hemoptysis was also used--it's actually the most common spelling I've seen--and don't forget all the "haemo-" spelling variations!
Here's a useful book, all online:
Robley Dunglison's 1865 Dictionary of Medical Science
The one disadvantage of searching inside is that if the main listing of the word has an accent symbol added to show the accented syllable, the search engine can't pick up the whole word. But one can usually get pretty close. For example, "hemoptysis" still gets you to the right page, because it picks up the word within the definition.
I don't see hemophthis as a synonym for hemoptysis, but a regular google search corrects it to hemophthisis (I really do think the doctor was trying for hemo- and -phthisis) and offers the definition "An obsolete term for anemia resulting from abnormal degeneration or destruction, or a deficiency in the formation of red blood cells." That makes sense: hemo=blood and phthisis=wasting.
But to further complicate things, I could imagine a doctor getting hemo=blood, phthisis=consumption and "hemoptysis" all mixed up, and writing hemophthis (mispelled without the extra "is") as a synonym for coughing up blood due to consumption. One would need to see the context in which "hemophthis" was written to figure it out and make sure he really was talking about coughing up blood.
On a separate note, I never know how to contribute to the A-Z type of threads, because I could just start at the beginning of Dunglison's book and work to the back, but it seems pointless to duplicate thousands of period definitions that are already readily available. A discussion like this, though, is pretty interesting, when you have what appears to be a doctor's own neologism for coughing up blood during consumption,
if that is indeed clearly from context what he's trying to say, rather than anemia. Incidentally, anemia or anaemia was a perfectly good period word too. TerryB, do you have the context in which hemophthis was used, and evidence the doctor meant hemoptysis?
