The benevolent Founder of this Ledure has indeed 
circumlcribed it within very narrow Limits, by con- 
fining it, in this Society , to the Phyfiology of the 
Motion of the Mufcles alone: Whereas, had he al- 
low'd it to be more generally anatomical, the Under- 
taker would find feveral very pleafing Fields to range in, 
relating to the animal Oeconomy, not yet taken no- 
tice of, that are capable of ftriking the Hearers with 
Amazement, and of producing, in the Royal Society , 
yet a greater Regard for the mod ftupendous and 
curious Subjeds in all Nature..

As to the Invention of any more Syftems towards

ever to render it familiar to any human Perception, 
however nearer one Authors Opinion may approach 
the Truth than that of another : And therefore I take 
the Liberty here to recommend to whomfoever fhali

World. Thus may feveral ufeful Dedudions be made 
from a Method of this Nature; a CorreElorium be 
produced for all former Treatifes of the Mufcles i
