As all these marks are characteristic of the parent rock-pigeon, I presume that no one will doubt that this is a case of reversion, and not of a new yet analogous variation appearing in the several breeds.

Although new and important modifications may not arise from reversion and analogous variation, such modifications will add to the beautiful and harmonious diversity of nature.

The weather cleared, as they descended the river, and under a sky at last cloudless, the Marches had moments of swift reversion to their former Rhine journey, when they were young and the purple light of love mantled the vineyarded hills along the shore, and flushed the castled steeps.

The effects of variability are modified by various degrees of inheritance and of reversion.

There may be truly said to be a constant struggle going on between, on the one hand, the tendency to reversion to a less modified state, as well as an innate tendency to further variability of all kinds, and, on the other hand, the power of steady selection to keep the breed true.

But for himself, now heir to the principality of Vaufontaine, and therefrom, by reversion, to that of Bercy, it had no importance.

The creature had seemed to undergo a sort of cataplasia, a reversion of its cells and tissues to a more primitive, almost embryonic form.

Consequently, sudden reversions to the perfect character of either parent would be more likely to occur with mongrels, which are descended from varieties often suddenly produced and semi-monstrous in character, than with hybrids, which are descended from species slowly and naturally produced.

Rattle-snake Reason and instinct Recapitulation, general Reciprocity of crosses Record, geological, imperfect Rengger on flies destroying cattle Resemblance to parents in mongrels and hybrids Reversion, law of inheritance Rhododendron, sterility of Richard, Prof.

As anything which disturbs the constitution is apt to lead to reversion, that is, to the resumption of a former character, it appears probable that when secondary radicles grow downwards or lateral shoots upwards, they revert to the primary manner of growth proper to radicles and shoots.
