He Brain of a Skait being taken out of the Skull, .1 Bel viflo, appears tampered of many ranks of ProeelfesJ to which are appendant (as outlets) the 0pm}; and Olfaétory Nerves. The Brain and Cerebeflum is framed of five rows of Protuberances, the firll is made of 1". four Procelfes, two lateral, and two interior; the outward ‘l‘are graced with a kind of pyramidal Figure, the Bafis adjoyning to the middle Needles, and the Cones to the Olfaétory Nerves. + I» [7. The middle pair i are greater and longer then the lateral, and fomewhat telembie l'arallelograrns. +ec. The fSecond row 1. are endued with an oval Figure, and are much lefs then the rl‘r. + dd. The third rank + are after a manner adorned with a pyramidal lhape. -I- e e. The fourth row + are fomewhat of a triangular Figure. +ff. The fifth row +make the Cerebeflum, and have an oblong irregular Figure, as well ' ' as the refit o the Procelles. And each fide of the Procelles of the CerebeL/um is encircled with Proccffes of irregular fhapes, not unlike Intellines, and fomewhat refembling the Anfmflur of a Hu- , mane Brain. 1- g g. Beyond the Cerebellum appears the Medufla Spinal}: "l divided into two equal parts 1' I: b. by the interpolition of a fmall Fiffure ‘l and each fide of the Medu/Ia .Spimli: is + iiiiii i i. garnilhed with numerous Nerves + deriving themfelves from its inward Recelles. f (k. The Optick Nerves + take their rife from the Meduflz ob/angata, and afterward creep our of the Brain, and after fome {pace are inferred into the Eyes. +7 I. TheOllaétory Nerves are two pair, of which the leali + feern to fpring outof the fecond row of Procelfes (endued with an oval Figure) and after tome fpace, are inferted into the greater Trunk of the firll pair of Olfaétory Nerves. + m m. The greater pair of Olfaétory Nerves + do fprout out of the Apices of the firii rank of Proceiles, and after an Inch or more, are branched obliquely on each 'l :1 mt. fideinto the numerous Fibrils + making a fine Syflem, the immediate Organ of Smelling.

The third rank 1» are alfo compofed of three Proceffes, of which the middle is the Ieafl, and are all adorned with a kind of triangular fhape. 'i' d.
