general, he has allotted the feveral appartments to the faculties of 

 the fenfitive Soul: His placing the Spirits to ferve to voluntary 

 aftions in the Cerebrum, and thole that ferve Involuntary in the 

 Cerebellum, is a noble and ufeful dijeovery. 



2 1 7. His affigning the cortical part for generating Spirits, and 

 the feat of Memory ; the Medullary, or Corpus callofum, for the o- 

 perations of the P bant a fie ; the Corpus ftriatum for the common 

 fenfe ; the Medulla oblongata, apromptuary for the Spirits, for per- 

 forming the office of Senfation, and ftontaneous motion ; and the 

 Prominentia orbiculares, and their Epipbyfes-, for conveying the 

 imprejfes of thepaff/ons, and natural infiincl, between the Cerebrum 

 and the Cerebellum, are highly ingenious and his own ; and fo is 

 his, and Dr. Lowers joint difcovery of the curious plexus, of the 

 Vertebral and fpinal Veins and Arteries ; their Neurologia is alfo 

 moft elaborate and no lefs admirable,tracing the Nerves from their 

 very fource, and following them through all the Meanders of the 

 Body, and thence (hew T ingus the reafon of the. fecret Jympathies - 

 of the parts. 



218. And although Dr. Willis was not the firft that mention'd

 And having fully difcovered the Hypoftafis of the fenfitive Soul, its 

 affeclions and fenfes ; he further obliges Mankind with a moft ratio- 

 nal account of the difeafes feated in it, and the Nervous Juice, ac- 

 cording to the different parts of the Brain, and the Syflema nervo- 



fum ' placing Cepbalalgies in the Meninges ; Lethargies, fomnolen- 

 tia continua^ Coma, Car us, Pervigilium, and Coma vigil, in the An~ 

 fraflus and Cortical part of the Brain ; the Incubus in the Cerebellum: 

 Then defcending to the Corpus callofum, he finds the Sprits there 

 fomtimes hurled round into Vertigoes, fomtimes exploded in 

 Spafms, Convulfwns, Epilepfies, fomtimes eclypfed in Apoplexies. 



219. In the Corpora firiata, and Medulla oblongata, if the ffi- 

 rits that ferve to motion be difturbed, thence he (hews come like- 

 wife Spafms and Convulfwns ; if thofe that ferve to fenfation, do-
