The only peculiarity in the neck is the excessive size of the body of the 6th verte- 

 bra, which is compensated by tlie smalhiess of the 7th, and that the spine of the 6th is 

 forked. There are 11 pairs of ribs, the last being about 12 cm. long. The lUtli vertebra 

 is ])eculiar. The articular processes change below it. It has a normal transverse process 

 on the left, but on the right this is more rib-like, being over o cm. long, and showing a 

 tendency to bifurcate at its proximal end. There is no head, 

 and it springs from the pedicle, but the bifui'catiou suggests a 

 representation of a tubercle. The next four verteljrae are 

 clearly lumbar; but the 24th is transitionid, being sacralized 

 on both sides. It, however, is to he counted as lumbar. The 

 spread of the lumbar transverse processes, beginning with the 

 2()th, is normal, and the 23d is a good penultimate. The sacrali- 

 zation of the 24th is further advanced on the left, Avhere it 

 forms a small part of the auricular surface. On the right it 

 does not touch the ilium. There is a transverse element on 

 each side, more isolated on the left than on the right. The 

 body is completely co-ossified with the 1st sacral. There is a 

 double promontory, of which the lowei- is the real one. The 

 arch is quite distinct in the middle, with a well-developed spine. 

 The 1st sacral (2-Jth) is the /'u/cra/is. There are eight pieces below the 24th vertebra, 

 which seem to consist of 4 sacral and 4 coccygeal. There is a foi-ameu between the 

 sac-rum and coccyx on the right, but on the left it is open. (An injury leaves the latter
