FOURTH PAPER. 
(First Paper, giving all explanations, Nat., March 1894, pp. 85-92.) 
THE Rey. W. Fowler, of Liversedge, has kindly pointed out to me 
that in the introduction to the first paper of this series, I did not 
define a phrase which I have since used freely; and as some slight 
misunderstanding has arisen, I take this ‘cabin of explaining 
it to make my meaning clear for the fut 
By dying out I mpl the gradual extinction of species through 
changes brought about by drainage, disafforestation, and the 
enclosure of moors, rabbit warrens, and wild haunts, for the purpose 
of cultivation, and by the ‘firing’ of commons purposely to destroy 
their native vegetation, or, what is more frequent, accidentally—in 
a word, by the change of environment from artificial causes. See 
Ranunculus Lingua \.., Corydalis claviculata DC., Viola palustris L., 
Genista anglica L., etc., in the published papers, and Drosera 
anglica Huds., etc., to appear. By the phrase “trust out, I shall 
mean the unassisted action of species on one another by changes in 
climate, desiccation, power of rapid reproduction, and_ hereditary 
thrust out our less vigorous species of water plants. It is often 
almost impossible to define approximately where artificial selection 
ends and natural begins, or vice versa. In the majority of cases 
known to be in operation at present—I might almost say in every 
case—they supplement each other's action continually, in the most 
obvious instances, artificial always preceding natural selection. 
£lodea, an American species, could not have acted as a disturber 
here, if it had not been idesaily introduced by human agency, 
nor would the gradual desiccation of the country have been so rapid 
if the forests had been left and the fens undrained. ‘The fringe of 
the subject is too wide to be even outlined here, ae the whole 
matter, I hope, will receive due treatment in the future 
Sept. 1894.
