I can feel no doubt 1859 1860 |
that all our domestic breeds

descended from the

livia with its geographical sub-species. |
In favour of this view, I may add,
firstly, firstly, 1859 1860 1861 1866 1872 | first, 1869 |
that
the wild C. livia the wild C. livia 1872 |
C. livia, or the rock-pigeon, 1859 1860 1861 1866 1869 |
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 that, although 1872 | although 1859 1860 1861 1866 1869 |

Thirdly, those characters which are mainly distinctive of each

Fourthly, pigeons have been

and tended with the utmost care, and loved by many people. They have been domesticated for thousands of years in several quarters of the world; the earliest known record of pigeons is in the fifth
ægyptian ægyptian 1859 1860 1861 1872 | Ægyptian 1866 1869 |
dynasty, about 3000 B.C., as was pointed out to me by Professor Lepsius; but Mr. Birch informs me that pigeons are given in a bill of fare in the previous dynasty. In the time of the Romans, as we hear from Pliny, immense prices were given for pigeons; "nay, they are come to this pass, that they can reckon up their pedigree and race." Pigeons were much valued by Akber Khan in India, about the year 1600; never less than 20,000 pigeons were taken with the court. "The monarchs of Iran and Turan sent him some very rare

and, continues the courtly historian, "His Majesty by crossing the breeds, which method was never practised before, has improved them astonishingly." About this same period the Dutch were as eager about pigeons as were the old Romans. The paramount importance of these considerations in explaining the immense amount of variation which pigeons have undergone, will
