scapula, was received the head of the shoulder-bone, or fore-thigh-bone ; as to 

 that protuberance called the acromium, was fastened the end of the clavicula. 



This thigh-bone of the fore-legs was about 24 inches long ; it was thick and 

 strong, having a large rough spine jetting forward, and running half its length. 

 The lower extremity of this thigh-bone, to which were fastened the tibia and 

 fibula, grew almost an inch in breadth. Above, where this bone began to 

 grow broad, on the outside there was a large protuberance ; and on the inside 

 a great oblong foramen, or hollow passage, formed by a small bone, arising 

 from the internal fore-part of the thigh-bone, where it begins to grow larger, 

 and is afterwards united to that part of the basis of this bone where the fibula, 

 or minus focile, is joined. Just in the middle of the basis of this bone, there 

 is a large sinus, which backwards appears deeper, locking into another deep 

 sinus of the tibia ; by which means these bones are so firmly articulated 

 together, as not easily, if possibly, to be put out of joint. 



The tibia or focile majus, was a strong bone, about 3 inches long ; which 

 was extended upwards about -j- of an inch above its articulation with the thigh- 

 bone; and at the other end, was fastened to the outward bone of the tarsus. 

 The fibula, or focile minus, is a smaller bone, placed more inward and for- 

 warder, and not so long as the tibia ; being articulated above, but not so firmly, 

 with the thigh-bone, and below, with the inner bone of the tarsus. For there are 

 but two bones of the tarsus, having each a small sinus, for receiving the heads of 

 the two fociles. The bones of the metatarsus were 4, or perhaps 5, to which 

 were joined the 5 fingers or toes of the fore-feet. The innermost toe had but 

 two articulations, or joints, but at the end had a large hooked strong nail : the 

 other 4 fingers had each 3 joints, armed with hooked nails, as the first. 



The hinder-legs were fastened to the trunk of the body by the os innomina- 

 tum ; which, in a straight line, was 3 inches long. In the head of the hinder 

 thigh-bone, and deeper in, there was a space for the fastening the ligament, 

 from which space there was a sinus which led outward ; so that the brims of 

 the acetabulum were not an entire circle, but broken off here. Here also are 

 the ossa marsupialia, orjanitores marsupii. The hinder-thigh-bone was a little 

 above 3 inches long ; it was a roundish strong bone. But the tibia, or focile 

 majus of the hinder-leg, was somewhat longer, and a little curved. The 

 fibula, or focile minus, was about the same length, but straighter and slen- 

 derer : this towards the foot was articulated to the os calcis, as the tibia to the 

 talus or astragalus ; and these two bones I make the tarsus ; and joining to 

 them were the bones of the metatarsus, and to these the phalanges of the 

 fingers or toes. In the innermost, or the thumb, there were only two joints ; 

 in the other 4 toes, or digiti, in each there were three. The end of the thumb
