A Yiew of the Outer Layer of the Mus- 

 cles on the Front of the Fore-Arm (Flex-

 Flexor Cubiti. 2, Brachialis Internus. 3, 

 Lower Internal portion of the Triceps. 4, 

 Pronator Radii Teres. 5, Flexor Carpi 

 Partialis. 6, Palmaris Longus. 7, Part of 

 the Flexor Sublimis Digitorum. 8, Flexor 

 Carpi Ulnaris. 9, Palmar Fascia. 10,

order that the fingers may be 

 desirable that there should be z 



dantly supplied with muscles, 

 many of which are fusiform 

 in their appearance, and all 

 of which are for the purpose 

 of moving the hand and fin- 

 gers. Most of the fibres run 

 in a direction parallel to the 

 bones of the fore-arm, but 

 those which perform the ac- 

 tions of pronation and supina- 

 tion lie obliquely, and some 

 nearly at right angles to the 

 long muscles. In this part 

 of the body the muscles are 

 distinguished by slenderness 

 of form and consequent deli- 

 cateness of tendon, the latter 

 in many cases being equal in 

 length to the muscular fibre, 

 since there are very few mus- 

 cles below the wrist, and those 

 only which are short and 

 thick, for the purpose of mov- 

 ing the thumb and little 

 finger. 



245. Tendons of the Fin- 

 gers, — The arrangement of 

 the tendons which are at- 

 tached to the phalanges, for 

 the motion of the fingers, 

 shows the contrivance and 

 skill of an Infinite Being. In 

 slender and easily moved, it is 

 s small a quantity of matter in

 and Supinators lie?
