Having difpatched his Differtation about the Five Senjes , he

its parts* 7, Shews the difference of the Spirits from 
thQl^rtal 'y which he efteems to be only this ^ That the Animal 
Spirits are Viral Spirits highly refrified, refined and perfefted in 
and by the Braioj for Senfarion. Lays open the origine of the 
Nerves^ proceeding from that part of the Brain^calFd Pons Cere-'
