the Major lyes in that part of the Procejfus Petrofus 
which regards the feat of the Brain {b ) This is 
twenty Lines or one Inch eight Lines long. The Medius

and the other is common with the Major for the 
fpace of three Lines ; ( ^ ) this is fifteen Lines or one Inch 
three Lines long : And the Minor which regards the Ca^ 
vitas Tjmpani, has one Orifice which is near to the 
Medius, were it approaches the ; and the other 
near to the Orifice of the Major. This is one Inch long. 
The feventh pair of Nerves called in general the Nrr-

divided into the hard and foft Portions, 
ojicog. EUph. ag other Animals. In this Subjed I 
Fig. IV. find one Lanule entring the Bone from 
the Tides of the Orifice for the Carotids 
Artery, about three Lines diameter/ e)( h) from thence 
running forward for the fpace of one Inch four Lines, 
then bending downwards one Inch, till it meets with 
the Orifice at the Sides of the Meatus Auditorius, by 
which it pierces the Scull, and pafies outward. This 
Canule, after it is entred the Proceffus Petrofus for the 
fpace of eight Lines, communicates with the 'Orifice 
which ufually enters the forefaid Procefs from the 
Bafe of the Scull ; and both thefe Orifices, after they 
have accompany’d one another about five Lines, are 
feparated, and the foft Portion penetrates the Bone at 
two places, as is faid. 
I have now endeavoured to give fuch a Defeription
