merely fat and skin. The bony structure is as follows: (Figure 1). 

 First come two slender spiculse of bone, tbe left (a) nearly three- 

 quarters of an inch in length, the right (a) somewhat shorter, con- 

 nected by a narrow trans- 

 verse piece. These are con- 

 tinuous with a single irreg- 

 ularly cylindrical bone (d) 

 an inch and a quarter long, 

 having at either end a pro- 

 tuberance directed forward. 

 To this, another bone (c), 

 seven-eighths of an inch 

 long, is anchylosed at a 

 right angle so as to point 

 forward. At the proximal 

 end this has a small process 

 jutting out on either side, 

 and below it shows a com- 

 mencing bifurcation. Next 

 come the phalanges. On 

 the right there are two (d 1 ). 

 On the left the proximal 

 phalanx (d) may be said 

 either to bifurcate or else 

 to have an outgrowth from 



its right side ;- each of these subdivisions has a small terminal phalanx 

 which is not so well developed as that of the right toe. The proximal 

 phalanx has also a slight knob on its outer and lower side opposite to 

 its bifurcation. This extremity was covered with fat and skin, having 

 no other tissue. There is considerable difficulty in naming the various 

 parts. To begin with the phalanges ; d' from its number of segments 

 is evidently the hallux, the sole representative of the right foot. If 

 we hold that d bifurcates we have two left halluces, which is absurd; 

 but if we consider the median toe to be an outgrowth from d we shall 

 have a left Hallux and a second toe. 



C evidently represents a double metatarsus and has at its lower 

 end somewhat the appearance of being inverted. There were 

 remains of joints between this bone and the phalanges, but above, all 

 the segments are coossified. The segments a, a 1 , and b are the most 

 difficult to identify. It might be argued that b represents the two
