 in the Knowledge of that, which in all Animal Bodies is

 In order to which, Lfliall follow the ufual Method of Dif- 

 fedtion, beginning with its Underfide, having already taken 

 a general Survey of the whole.

all over the Bottom of the Brain, and is a 

 curious Net- work of Blood-vcllels form'd out of the fmall 

 Twigs which fpring from the largeft Branches of the Can- 

 tid and Cervical Arteries, having palled through the Skull 

 by proper Holes in the Bones of the Temples. Thefe Vef- 

 fels are the more adapted and fitted to the Nourifliment of 

 the Brain, as they are thus interwoven one with another, by 

 which Means the Blood takes a much longer Stay than if 

 they obferv'd a more ftreight and equal Diredlion.

Pituitaria \^\ng obfervable : Towards the Bottom of 



the Brain it is inclofed within the Mem- 

 branes, and feated in a fmall Cavity in the Os cwmforme^ or 

 Wedge- like Bone, appointed by Nature for that Purpofe. 



It has a Conduit called the Infundibulum^m 

 'The Intundi- Funnel, which conve)"s the Excrements of

tomifts have believed there was a Paflage from it to the 

 Nofe : But later Enquiries have difcover'd two fmall Duds 

 ■which it fends off to the Jugular Veins ; fo that forae are 

 of Opinion, it is again mixed with the Blood. This Fun- 

 nel, or hifundibulum^ is faid to take its Rife from the fore- 

 part of the third Ventricle, into whicli this Moillure feem^

 Gland above-mention'd, where it probably undergoes ano- 

 ther Degree of Refinement, that it may be the better adap- 

 ted to the Furpofes of Nature. 



Anatomifts have, it feems, been very much puzzled to 

 find proper Refcmblances for leveral Parts of the Brain, hav-

 Buttocks, being the largeft, and the two Slonss, which ate
