![geofis of the Royal Navy, under the nosological title of nyctalopia, while others, with Dr. Cullen, have termed it dysopia tenebrarum. Hippocrates (if his text is correct) and others have confined the term nyctalopia to that disease in which the patient is blind by day and can see clearly by night. Waving the discussion of the propriety of the adoption I have made, if we view the word he¬ meralopia as derived from yjfjJpct, dies, and oktco, video, to see by day, and nyctalopia from ^ j, nooc, and oftra, video, to see by night, which I believe to be the common opinion ; the propriety of Vo¬ gel’s choice is at once evident; but it may be ob¬ jected to the correctness of this derivation, that the 66 al” in both words denotes (alpha privitiva) in which case the sense of the above translations wTould be wholly reversed. Hippocrates’s definition of nyctalopia, denotes the very opposite of night-blindness ; O; ^ rtjg WKTog o^uvrsg dig Stj vv%rd\ti7rccg zccXlofJLSv, Quos * O* tvs yjxros ogw»TEj] Nt/xTaXam? dicuntur praecipuo signifi- cato, qui nocturna coecitudine laborant, & noctu nihil cernunt, sole oceiduo obscurius, ut scribunt Paul us & -ZEtiiis.
