Fig. 3. — A, B, C, D, E and F. To show contrast in constitutional vigor in females 

 of six varieties of fowls. The differences are much more apparent when com- 

 paring the live fowls. The photograph fails to show clearly the brilliancy of the 

 plumage, and to catch the natural attitude and expression of the fowl.
