In favour of this view, I may add,

first,

firstly,

that →C. livia, or the rock-pigeon, has been found capable of domestication in Europe and in India; and that it agrees in habits and in a great number of points of structure with all the domestic breeds. Secondly,

that, although

tumbler differs immensely in certain characters from the rock-pigeon, yet

that, by

comparing the several sub-breeds of these

varieties,
