[411] Every naturalist admits that there is a general tendency in animals and plants to vary; but it is usually taken for granted, though we have no means of proving the assumption to be true, that there are certain limits beyond which each species cannot pass under any circumstances, or in any number of generations. Mr. Darwin and Mr. Wallace say that the opposite hypothesis, which assumes that every species is capable of varying indefinitely from its original type, is not a whit more arbitrary, and has this manifest claim to be preferred, that it will account for a multitude of phenomena which the ordinary theory is incapable of explaining.

Aryan Hypothesis and Controversy  -- The Races of Manldnd change more slowly than their Languages  --  Theory of the gradual Origin of Languages  -- Difficulty of defining what is meant by a Language as distinct from a Dialect  --  Great Number of extinct and living Tongues  --  No European Language a Thousand Years old  -- Gaps between Languages, how caused  --  Imperfection of the Record  --  Changes always in Progress  --  Struggle for Existence between Rival Terms and Dialects  --  Causes of Selection  --  Each Language formed slowly in a single geographical Area  --  May die out gradually or suddenly  --  Once lost can never be revived  --  Mode of Origin of Language and Species a Mystery  -- Speculations as to the Number of original Languages or Species unprofitable.
