In one of the blind animals, namely, the cave-rat (Neotoma), two of which were captured by Professor Silliman at above half a mile distance from the mouth of the cave, and therefore not in the profoundest depths, the eyes were lustrous and of large size; and these animals, as I am informed by Professor Silliman, after having been exposed for about a month to a graduated light, acquired a dim perception of objects.
Animalia itsuetarikoak diren harpeko bi arratoi (Neotoma) harrapatu zituelarik Silliman irakasleak haitzuloaren ahotik milia erdi ingurura, eta beraz, ez sakonerarik handienean, begi lustretsu eta tamainu handikoak zituzten; eta animalia hauek, Silliman irakasleak esan zidanez, hilabeteaz gero eta argi biziagotan eduki ondoren, objektuak lanbrotsuki hautematea lortu zuten.
