The Obliquus fuperior has its Rife from the Edge 
of the Hole through which the optic Nerve paffes, 
between the Elevator and AdduFtor, runs along the 
Of planum upwards, paffing thro’ the Trochlea , a lit- 
tle Fully fixed to the frontal Bone, and, doubling 
downwards again, is fixed by a thin Tendon into the 
fame Coat, behind the tendinous Expanfion of the ■ 
Elevator , whofe Office is to incline the Eye for- 
wards, with its Pupil downwards.

The Obliquus inferior arifes tendinous from the 
Edge of the Orbit, where the Os maxillare joins the 
Os Mali , and ends backwards and inwards between 
the optic Nerve and the Tendon of the AbduFlor, 
drawing the Eye forwards, and inclining the Pupil 
upwards.

Observation - . 
Altho’ the Eye is faid, in our Description, to be 
drawn this or that Way (and it is indeed the Language 
of all Anatomifts) according as the Mufcle a£ts; yet, 
ftri&ly Speaking, it is only turned or rolled this or 
that Way, as a moveable Ball in a Socket ; by which 
Motion it is the Pupil alone that can be faid to 
change its Place, as a Spot upon a Globe, whofe 
Situation is alter’d by the Motion of fuch a Body 
round its Axis : So that, fince the Eye is moved 
only for the fake of Vifion, when the Elevator, for 
Example, is contracted, by drawing the Place of the 
Globe, ;
