( On the Right Side. 



At the proximal end of the metacarpus. Dis- 

 tance between the lateral And the mesial 

 margins of the surface of articulation with 

 the carpal bones 3'02 



At the proximal end of the metacarpus. Dis- 

 tance between the lateral And the mesial 

 scabrous elevations immediately digitad 

 from the articular margins 3' 11 



Greatest distance, interveningly to the prox- 

 imal and the digital ends of the metacarpus; 

 between the lateral And the mesial surfaces 

 of the caudal margins of the groove occu- 

 pying the caudal surface of the bone . . 1"78 



Smallest distance between the lateral And the 

 mesial surfaces of the rostral and more 

 solid portion of the metacarpus; interve- 

 ningly to the proximal and the digital ends 

 of the bone 1 '55 



At the digital end of the metacarpus. Distance 

 between the lateral And the mesial termina- 

 tions of the rostral articular margins . . 4'22 



Atthe digital end of the metacarpus. Distance 

 between the sinuosity on the caudo-digital 

 extremity of the lateral articular margin, 

 And the opposite and similar sinuosity on 

 the mesial articular margin 3 '82

At the proximal end of the metacarpus. Dis- 

 tance from the lateral pitted surface imme- 

 diately digitad from the rostral articular 

 margin. To the opposite and similar caudal 

 surface 1*49 



At the proximal end of the metacarpus. Dis- 

 tance from the rostral protuberance imme- 

 diately digitad from the rostro-mesial arti- 

 cular margin, To the opposite caudal sca- 

 brous surface 2'07 



Greatest distance, interveningly to the prox- 

 imal and the digital ends of the metacarpus; 

 from the rostral surface of the lateral por- 

 tion of the bone (divided from the mesial 

 portion by a furrow-like depression). To 

 the opposite caudo-lateral margin of the 

 groove occupying the caudal surface . . 1 "45 



Greatest distance, interveningly to the prox- 

 imal and the digital ends of the metacarpus; 

 from the rostral surface of the mesial por- 

 tion of the bone. To the opposite caudo- 

 mesial margin of the groove occupying the 

 caudal surface 1'43 



Smallest distance from the rostral surface 

 of the metacarpus. To the opposite caudal 

 surface; over the digital bifurcation of the 

 bone. Being the smallest distance interve- 

 ningly to the proximal and the digital ends . 1'04 



Atthe digital end of the metacarpus. Distance 

 from the rostro-lateral articular margin of 

 the lateral condyle. To the hollow of the 

 disjunction of the lateral and the middle of 

 three tubercles on the caudal articular mar- 

 gin of that condyle 1*80 



At the digital endof the metacarpus. Distance 

 from the rostro-mesial articular margin of 

 the lateral condyle. To the caudal extremity 

 of the mesial of three tubercles on the cau- 

 dal articular margin of that condyle . . 2'01 



At the digital end of the metacarpus. Distance 

 from the rostro-lateral articular margin of 

 the mesial condyle, To the caudal extremity 

 of the lateral of three tubercles on the cau- 

 dal articular margin of that condyle . . r95
