2. The greatest mesial extent of the pelvis is equal to the 

 coronal length of the head. 



3. The length of the union of the ossa pubis is equal to the 

 length of the union of the lower jaws. 



4. The lateral length of the pelvis is equal to the distance 

 from the muzzle to the caudal surface of the zigomatic inclo- 

 sure. 



5. The greatest rostral breadth of the pelvis is equal to the 

 zigomatic length of the head. 



6. The acetabular breadth of the pelvis is equal to the greatest 

 breadth of the head. 



7. The greatest caudal breadth of the pelvis is equal to the 

 distance from the muzzle to the end of the pterygoid pro- 

 cesses.

• The lengths of the four long bones of the atlantal limbs, in- 

 dependently of processes and elevations, are consecutively as 

 the numbers 22. 28. 20. 6 :— Sum 76". 



The similar lengths of the four long bones of the sacral limbs 

 are consecutively as the numbers 



28. 23. 20. 5:— Sum 76. 



The correspondence is obvious : 



The second number of the atlantal series is identical with the 

 first number of the sacral series. 



The last number in each series expresses the difference of the 

 first and the second numbers of the series. 



The penultimates are identical, and the sums are equal. 



Osteologically, Notwithstanding the dissimilitude of flexure 

 in the atlantal and the sacral limbs ; 



The sums of what may be termed their articular lengths are 

 equal.
