Since the bronchial branches are known under a variety of 

 names, it will be advantageous before proceeding further to in- 

 dicate the nomenclature employed in this paper. The different 

 secondary outgrowths from the primary lung tube have the same 

 histological structure, but they vary in position, in size, and in 

 the profusion and distribution of their branches.
