![nyctalopas nuncupamus, qui noctu cernunt. Lib. ii, sectio li. The note on this passage of Hippocrates, adduces various authorities for believing that those only are properly termed “ nyctalopes,” who are affected with night-blindness, and in books the 4th and 6th, section 7th, the word vv%Tct,\ooneg> is every where rendered into Latin, by “ nocturnse caecitu- dines,” or those who are blind by night. Fsesius* edition. Celsus describes night-blindness under the head of u De imbecillitate oculorum.—Praeter hsec, im- becillitas oculorum est, ex qua, quidam interdiu satis, noctu nihil cernunt,” lib. vi. cap. vi. This description is clearly applicable to night-blindness. Linnaeus defines nyctalopia to be, cc Oculi vi- sus nocturnus,” the sight possessed by night, class xi. ordo vii. 307. and Vogel, “ Visus noctu sal¬ tern contingens,” the sight only possessed by night, class vi. 243. Agreeably to the definitions of these nosologists, the name nyctalopia cannot cernunt, interdiu verd deterius,et si lunalueeat,nihil cernunt: quod tamen rarum est, ut testatur iEtius, illud vero frequens & maxime usitatum, &c. p 110. Fcesius* edition of Hippocrates, Franc. 1621. Tottxi ^ wxTcthbj7TE5] Hie w)vitii et affectionis oculorum nomen est, qua noctu nihil cernunt, nocturnam coecitudinem di- cunt, cum prsecipuo significato wxrocXu^sg dicantur eo affectu et nocturna ccecitudine laforantes. Note in lib, vi. sect. vii. p. 1195, From these notes it appears that the commentators have assumed it as a fact, that Hippocrates has, in these passages of his works, intended to treat of night, instead of day, blindness.](https://iiif.wellcomecollection.org/image/b30389197_0006.jp2/full/800%2C/0/default.jpg)
