THE CCELIAC ARTERY IN THE RABBIT 99 



The whole question as to the cause or causes seems at present 

 to be without a solution. It seems, therefore, that the entire prob- 

 lem of abnormalities or variations waits upon the further knowl- 

 edge of embryology and a solution of the factors which govern 

 and regulate embryonic development.
