This is an introductory audio-tutorial on the living eye. The narrative is 40 minutes long (plus or minus a tad). The lesson opens with an exercise involving diagrams (found below). RECOMMENDATION: have a small mirror handy following the exercise with the diagrams.

SOUND CONTROL-- wait for tape to load before trying to play! (How can you tell? The tape is loading if the little rectangle in the sound control is changing color.)

ERRATUMcartoon (GOOF-UP): There's an error on the tape involving the eyelids . They may be called "palpebrae"; that's correct, for the plural. But the singular is palpebra, not, as the guy on the tape says, palpebrum. Anyway, he fined himself a butter pecan ice cream cone for the error.
