* firft, which we may denominate the mufcular, 
* originating in the lobes of the brain, proceed 
* back to infert themfelves into the mufcle retrac- 
‘ tor of the ovular globe ; the other five are dif- 
‘ tributed before, and are the upper and under 
‘labial, the mandibular, the optic larger and 
‘fmaller. The upper labial arife in the anterior 
‘ part of the brain, and, traverfing the fides of 
‘the oval, divide before into two confpicuous 
‘ filaments ; one proceeds to the higher part of 
‘the upper lips, and the other terminates in the 
* lower part of them. ‘The mandibular nerves 
‘ originate in the pofterior part of the brain, and, 
“ proceeding back, are inferted in the ovular 
‘globe, in the vicinity of the falival dués, di- 
‘verging into the mouth, throat, and palate. 
The optic nerves iffue from the fides of the 
€ brainy and, by means of either membrane, are 
‘ attached to the mufcle motor of the larger horns, 
‘and terminate in a pyriform bulb af their ex- 
‘tremity. The fmaller optics, or more properly 
“nerves, of the fmall horns alfo arife from the 
‘ fides of the brain, in the vicinity of the larger 
ones. They unite to the mufcle of thé fmaller 
‘horns ; and, divided into feveral filaments, pro- 
‘ ceed to terminate in the extremity of the horns, 
‘in the cutaneous mufcle and the extremity of 
* the under jaw. |
