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 vvhich runs the tendon oi' Ūig perforans. Another musele arises 

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

 and from the fibres of the rectus femoris ; lt covers the tibia and filis 

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

 passes through thejbramen situated at the anterior surface of the 

 tibia betvveen 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 musele arises frona the anterior and external parts of the head 

 of the Jibula; 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 j^asaa. Another 

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

 from the vvhole of tbe^b^sa and its edges on the head of the tibia, 

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

 has the sarae distribution as in the Locn and Guli, except that the 

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

 other musele arises fleshy from the vvhole anterior part oithejibula, 

 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 museles arising from the metatarsal bone, one on each 

 side, and one in the Jbssce 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 museles: an extensor, on its superior 

 surface; a.Jlexor, on its inferior; and an abductor, on its internal 

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



" The diaphragm consists of twelve narroiv 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 vvith that of the 

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

 stomach. The coeliac 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 thelarge curvature of the stomach, and near the pylo- 

 ms gives ofF the superior pyloric and left hepatic ; the inferior passes 

 dovvn the right side of the stomach, and disappears at the pyloms, 

 being here minutely ramified upon it. The hepatic gives oft" the 

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