differentiated races or species, with a fifth, which 

 he has examined less. These, which frequently 

 run athwart the breeds, so-called, of the fanciers, 

 are : 



1. The type of the English carrier. 



2. The Bagadotten carrier of Germany. The 

 runts belong to one or both of these types. 



3. The type of the rock dove, including most 

 pouters, also fantails, trumpeters, nuns, swal- 

 lows, etc. 



4. The type of the tumbler, including tumblers- 

 and barbs. 



5. Another type among pouters distinguished 

 by the number of its vertebrae, but whose 

 craniology is not further known. See " La 

 Philosophic Positive Revue," No. X. p. 89, and 

 prec. and seq. 



It is evident that these results place the whole 

 question in a light entirely new, and that should 

 they be confirmed by future investigation, the 

 whole of Darwin's argument as to the breeds of 

 domestic pigeons will fall to the ground.
