statement somewhat (luestiouable. but it i.s made lieeau.se certain appearances of the bone 

 seem to justify it.) In this spine we have, as shown by the 19th, the 24th, and 29th 

 vertebrae, a tendency for the sacrum and loins to move up higher (m the left.

The cervical and thoracic regions present nothing noteworthy till we come to the lUtli 

 vertebi'a. This has on the right a transverse process of normal shape and origin, but nn- 

 usnally long and broad. The left one is of the usual proportions, but is free. The spinous 

 process is distinctly lumbar. The change in the articidar processes is above this vertebra, 

 though rather transitional on the right. For these reasons 1 have decided to call the ver- 

 tebi'a a lumbar, but with hesitation. The spread of the transverse processes in the loins is 

 irregular ; but owing to the twist of the spine and to sonre injuries of the processes the details 

 cannot be given. The 2.3d is much like a last lumbar and there is no characteristic penul- 

 timate. There is a double promontory, above and below the 24th vertel)ra. It is hard to 

 say which is the greater. The body of the 24th is partially co-ossified witli the one l)elow 

 it, with some slight remnants of a disc persisting. The costal element, strongl}' developed 

 on both sides, especially on the right, fuses with the sacrum. The arch is thoroughly ab- 

 sorbed into the sacrum, and the spinous process is replaced by a tubercle. These facts 

 would induce one to call the vertebra sacral, wex'e it not for its relations to the auricular 

 surface. On the left it has nothing to do with it ; on the right it forms a considerable 

 part. Just how much is hard to determine ; but I believe the 25th to be certainly the 

 fulcralis. Below the 24th are five sacral vertebrae. The conJHr/nfa vera of v. Meyer is in 

 the 3d. The extent of the auricular surfaces downward cannot be ascertained on accotmt 

 of injur}'. There is Init one coccygeal vertebra, the rest liaving been lost. It seems to be 

 partially fused with the sacrum, but this is probably a late-occurring change.

The neck and back show nothing particular. The change of the articular surfaces is 

 between the 19th and 2()th, except that the left superior joint of the last thoracic (19th) 

 is somewhat transitional. The 20th vertebra is a typical 1st lumbar. The spread of the 

 lumbar transverse processes increases up to the 3d. Those of the 4th are small, as is ct>m- 

 mon in that vertebra. The 24th vertebra is the turning-point of the discussion, and is par-
