    The definition given by Vogel of hemeralopia^ or night-blindness is, 6 visus noctu abolitus.’ chap. 6. gen. 244. V Of this genus I shall venture to distinguish two species ; and trust, that the history of the disease will vindicate the propriety of the division. Species I. Idiopathica. Hemeralopia sine causa manifesto ——— II. Symptomatica. Hemeralopia scorbutica. After Vogel’s very plain definition of the dis¬ ease, which is the subject of this essay, it might be thought superfluous to notice the nosological differences, which have existed at all periods re¬ specting its proper generic name ; were it not ne¬ cessary to be aware that the generic titles of nyc¬ talopia and caligo tenebrarum have been also as¬ signed to it by different writers who have describ¬ ed it. Hemeralopia, or night-blindness, has been no¬ ticed by Paulus iEgineta, iEtius, Galen and other commentators on Hippocrates, by Bontius’s trans¬ lator, in Sir Gilbert Blane’s Treatise on the Dis¬ eases of Seamen, by Mr. Forbes * and other Sur- * Observations on Tropical Nyctalopia, by Mr. J. Forbes, Sur¬ geon, Royal Navy, Edinburgh Medical and Surgical Journal* No. 28. Page 417. seq.
