XIIL Our Author defines a Mufcle, as con filling of an infinite Number of tendinous Fibres like Cords 5 which are fo blended together at the Extremities, as to re- fetnble a thick Cord compofed of many others 5 but that within the Body of the Mufcle thofe Fibres are at feme Diftance from each other, and the Spaces between them filled up with Flefh5 which, with Membranes, Blood-veflels, Nerves, and innumerable Lymphasduds, confiitutes the intire Mufcle. This Flefh, in the Spaces betweent he Fibres, he fays, is no¬ thing elfe than that Portion of Blood flowing thro0 thefe Interftices ,* which, being condenfed * by the Coldnefs of the Fibres, is detain'd between them, and conflitutes the Mufcular Flefh. XIV, He has given an ingenious Scheme for explaining the Manner in which a Mufcle is moved, after hav¬ ing laid down the above Prreludiathe Sum of which is. That a certain Power is determined from the Brain, by * It is to be fear’d, if Blood could be evafated, the leaft con¬ denfed Particle would be fufficient to form, by degrees, Abfcefles, or fome other Miichicf. c
