tlie scabrous surface situated on the internal part of the posterior 

 face of the tibia about halfway down that bone, and forms a tendon 

 which is attached to the upper part of the internal edge of the groove 

 in which runs the tendon of the /7er/oraws. Another muscle arises 

 from the external condyle, from the patella on its anterior surface, 

 and from the fibres of the rectus Jemoris ; it covers the tibia and fills 

 up the space between it and the Jibula, and forms a tendon which 

 passes through the foramen situated at the anterior surface of the 

 tibia between its condyles, under the capsular ligament of the ancle- 

 joint, and is attached to the prominence situated between the second 

 and third portions of the metatarsal bone near its tibial extremity. 



" A muscle arises from the anterior and external parts of the head 

 of the^6M/a; it becomes tendinous about halfway down the leg, 

 passes under the annular ligament, and is inserted into the external 

 side of the metatarsal bone near its postero inferior angle: another 

 slip goes under the foot and forms the plantar ^ia'a. Another 

 muscle arises from the anterior inferior surface of the patella, and 

 from the whole of the fossa and its edges on the head of the tibia, 

 passes downwards, and is tied down by the annular ligament ; and 

 has the same distribution as in the Locn and Gull, except that the 

 tendon is more closely tied down, smaller, and not so round. An- 

 other muscle arises fleshy from the whole anterior part o( the Jibula, 

 interosseous ligament, and part of the external side of the tibia ; it 

 forms its tendon near the ancle-joint, and is attached to the pos- 

 tero-external angle of the metatarsus on its plantar surface. There 

 are also four muscles arising from the metatarsal bone, one on each 

 side, and one in the foosstB between the three portions of the meta- 

 tarsal bone : they all arise near the tibial end on its superior surface, 

 and are attached to the phalanges of the first, second, and fourth 

 fingers. The thumb has three muscles: an extensor, on its superior 

 surface; ajlexor, on its inferior j and an abductor, on its internal 

 surface; all attached to the tibial end of the metatarsus as usual. 



" The diaphragm consists of twelve narrow fleshy slips, which 

 arise, six on each side, from the internal surface of the ribs : near 

 their angle they pass upwards, and are inserted tendinous into the 

 thin transparent membrane covering the lungs. The blood-vessels 

 pass in front of ic. 



" The circulatory system corresponds exactly with that of the 

 Loon, except in the origin and distribution of the arteries of the 

 stomach. The cceliac artery comes oft' on a level with the fifth rib ; 

 it passes a little forwards, and divides into the coronaria ventriculi, 

 the hepatic, and the splenic. The coronaria ventriculi, just after its 

 origin, divides into the superior and inferior coronaries : the superior 

 passes round the large curvature of the stomach, and near the pylo- 

 rus gives off" the superior pyloric and left hepatic; the inferior passes 

 down the right side of the stomach, and disappears at the pylorus, 

 being here minutely ramified upon it. The hepatic gives ofl' the 

 right gastro-epiploic, which goes on the inferior angle of the sto-
