mTHac the Learned Author of this difficulc Argument had 
heretofore promifed , he now in this Eook with much 
care performeth ; which is the Pathologj of the Brmn^md the Ner- 
vous kind, explicating the Difeafes that aftecTt ic,and teaching their 
Cures 5 together with fome previous Phyfiological Confiderations 
oi t\\tSoule of Brutes, 
And bcc^ufe it may, by fome, be thought fomewhat paradox- 
ical, that he afligneth to that Soul, whereby both Brutes and Men 
have life, fenfe, and local motion, not on^y extenfion, and as 
'twere Organical parts, but a!fo peculiar Difeafes, and appropri-

Soul, efteeming, that both by confiderable Arguments , and by

and befides, that its Bipmition is by a necelTary confequence 
deducible from the fammepu^ Life of the EUud , and the hctd or 
Ethereal fubftanccof the Jnimd Spirits - hoth which he hath 
formerly aflerted, and endeavoured to prove. For, if it be gran- 
ted him, that the F/W portion of this Soul, lodging in the Bloud, 
be a kindof Fire, dXidtht Senjitive part be nothing but an 'Ag- 
gregate of Animal Spirits, diffufed all over in the Brain and 
Nerves; he draws this confequence, That the Soul of a Brute ^ 
co-extended to the whole Body , hath not only many and diftind, 
but alfo fomewhat difllmilar, parts* And if it be objefted, that 
the Soul of a Brute is immaterial , becaufe it perceivetb, oris 
aware that it feels ^ Matter feeming incapable of Perception ; he
