^oz The V^atural Hijlory 
general, he has allotted the feveral appartnients to iht faculties of 
the fenfitive Soul: His placing the Spirits to ferve to voluntary 
anions in the Cerebrum^ and thofe that ferve Involuntary in the 
Cerebellum^ is a noble and ufeful dijcovery, 
2 1 7. Hisaffigningthe cortical part for generating Spirits^ and 
the feat of Memory ; the Medullary^ or Corpu6 callofum^ for the o- 
perations of the P bant a fie ; the Corpus Jiriatum for the common 
fenfe ; the Medulla oblongata^ a promptuary for the Spirits^ for per- 
forming the office of Senfation, znd fpontaneou^ motion ; and the 
Prominenti<e orbicular es^ and their Epipbyfes-) for conveying the 
impreffes of x\\tpaJfions^ and natural inftinSi^ between the Cerebrum 
and the Cerebellum^ are highly ingenious and his own ; and fo is 
his, and Dr. Lowers joint difcovery of the curious plexm^ of the 
Vertebral and ^inal 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 fliew^ing us the reafonof the i^ecret jfjimpat hies ^ 
of the parts.

lucida'. Where he difcourfes of the manner how the Soul performs 
Its operations mws % he does it, as indeed he has done all, with 
the greateft Improvements within the compafs of Wit and Reafon : 
And having fully difcovered the Hypo^afis of the fenfitive Soul^ its 
affeSiions and [enfes ; he further obliges Mankind with a moft ratio- 
nal account of the difeafes feated in it, and the Nervous J^uice^ ac- 
cording to the different parts of the Brain^ and the Syfiema nervo- 
fum ' phc'ing Cephalalgies in the Meninges Lethargies^ fomnclen- 
tia continua^ Coma^ Carips^ Pervigilium^ and Coma vigil^ in the An^ 
fra5fu^2ind Cortical part of the Brain ; the Incubm in the Cerebellum: 
Then defcending to the Corpus callofum^ he finds the Spirits there
