sible) the occult cause of these anomalies in the generative and 

 nutritive processes. 



The first instance of deformity 

 I have to notice, is that of a 

 lamb exhibiting considerable de- 

 ficiency in the facial portion of 

 the head, which was small, and 

 > j had no vestige of the projecting 

 iy portion of the face. It had but 

 ^l^^lone eye, and that placed in the 

 .#|J centre of the forehead ; its two 

 j^ ears were confusedly united into 

 one, as shown inJ/%-. 84., and 

 formed one impervious concha 

 placed immediately beneath the 

 eye, as exhibited in^^. 85.; below these there was nothing 

 visible, more than a regularly enlarging neck. Dissection 

 85 . M^^^!^^^ showed the following dis- 



position of the soft parts : 

 — The eye was rather 

 large in proportion to the 

 size of the head, but in 

 every respect a single 

 eye ; the optic nerve 

 passed into the cranium 

 in a straight line back- 

 wards from the retina; 

 the eye was covered by 

 the tunica conjunctiva, 

 which was reflected, and 

 lined the upper eyelid, 

 but was below united to 

 the very edge of the skin 

 that formed the inferior 

 border of the opening for the eye : indeed, there was no lower 

 eyelid.; the superior palpebra was perfectly formed, except that 

 there was neither punctum lachrymale nor canalis lachrymalis, 

 and consequently no saccus lachrymalis, nor ductus ad nasum : 

 it had a tarsus, cilia, and glandulae Meibomianae. There were 

 muscles attached to the eye and also to the ear, and nerves and 

 arteries, but I had not time to trace them. I observed that 

 the arteries, veins, and nerves which supplied the imperfectly 

 formed parts that I am about to mention were remarkably 

 small. The ear had no meatus externus, nor auditory 

 canal. Below this misplaced double ear, and hidden beneath 

 tjie jcommon integuments, were observable the rudiments of
