Muscle, the shell-fish, its description ; its organs of genera- 

 tion are what most deserve to excite our curiosity; it en- 

 deavours to become stationary, and to attach itself to any 

 fixed object it happens to be near; its enemies: it is sup- 

 posed that those threads, which are usually called the beard 

 of the muscle, are the natural growth of the animal's body, 

 and by no means produced at pleasure, as Reaumur sup- 

 poses ; its instrument of motion, by which it contrives to 

 reach the object it wants to bind itself to; its food; some 

 of this kind have been found a foot long ; the natives of 

 Palermo sometimes make gloves and stockings of its beards ; 

 the places where found ; it requires a year for the peopling 

 a muscle bed, v. 231. 



Muscles, to judge of the strength of animals by the thickness 

 of their muscles inconclusive, i. 44-3. The pectoral muscles 

 of quadrupeds trifling, in comparison to those of birds ; in 

 quadrupeds, as in man, the muscles moving the thighs and 

 hinder parts are strongest, while those of the arms are 

 feeble ; in birds the contrary obtains, iv. 6. Those of the 

 shark preserve their motion after being separated from the 

 body, v. 231.
