termM Glandula Vinealis ; tho' Snape will have It from 

 its Shape, which is like a Pine Kernel, to be called 

 Pineal ; I fay, this Glandule was the famous Dts 

 Cartei's imaginary Seat of the Soul ; though in my 

 Opinion, this Author feated the fame very homely : 

 For, this Gland in a Human Body, does not exceed 

 the Bignefs of a Pea, and is placed in the Anus of 

 the Brain, and no doubt ferves for the fame, and no 

 other Purpofes. 



The Medullary Jubilance of the Brain is the Be- Each Fi- 

 ginning of all the Nerves, as I have already faid ; ^-"^^ o^ the 

 and it is very probable that eacli Fibre of the f^^'^'^h ^^ 

 Nerves, anfwers to a particular Part of the Brain Sfto'^a'

 continual Heat and Pulfe of them. They have alfo ^^^^' 

 Blood- Veffels as the other Parts of the Body ; and 

 thefe VefTels are not only fpread upon their Coats, 

 but they run alfo among their Medullary Fibres, as 

 may be feen amongft the Fibres of the Retina, 

 ( a fine thin Membrane at the Bottom of the Eye, 

 immediately fpread upon the Optick Nerve, ) which 

 I fhall defcribe when I come to treat upon the 

 Diflempers of the Eye. Therefore, at prefent, I 

 fhall clofe this Defcription of the Nerves,, for it 

 would be tedious to the Reader to enumerate the 

 ten Pair of Nerves which arife immediately within
