The author demonstrates that the processus odontoideus is 
originally separated from the centrum of the epistropheus by 
two intervertebral epiphyses, that it has parts corresponding to,^ 
but not developed into, an arcus, that its formation is analogous 
to that of a caudal vertebra ; consequently the epistropheus is 
cottiposed of two centra, coalescent like the sacral vertebrae.
