Our Author defines a Alufclc, as confiding of an 
infinite Number of tendinous Fibres like Cords ; which 
are fo blended together at the Extremities, as to rc- 
fetnble a thick Cord compofed of many others ; but 
that within the Body of the Mufcle thofe Fibres arc 
at fome Diftance from each other, and the Spaces 
between them filled up with Flefh ; which, with 
Membranes, Blood-veflels, Nerves, and innumerable 
Lympha:duds, conftitutes the intire Mufcle. This 
Flefh, in the Spaces betweent he Fibres, he fays, is no- 
thing elfe than that Portion of Blood flowing thro' 
thel'e Interftices ,• which, being condenfed * by the 
Coldnefs of the Fibres, is detain’d between them, and 
Conftitutes the Mufcular Flelh.

He has given an ingenious Scheme for explaining 
the Manner in which a Mufcle is moved, after hav- 
ing laid down the abo vcPrte Indian the Sum of which 
is, That a certain Power is determined from the Brain,
