Conclusion 253 
Linnean Society, Mr. Tylor being then too ill to read it 
himself. The paper has since been edited by Mr. Skertchly, 
and published.* Anything that should be said further about 
it will come best from Mr. Skertchly ; it will be enough 
here if I give the résumé of it prepared by Mr. Tylor 
himself. ; 
In this Mr. Tylor said :—‘‘ The principles which underlie 
this paper are the individuality of plants, the necessity for 
some co-ordinating system to enable the parts to act in 
concert, and the probability that this also necessitates the 
admission that plants have a dim sort of intelligence. 
“It is shown that a tree, for example, is something more 
than an aggregation of tissues, but is a complex being 
performing acts as a whole, and not merely responsive to 
the direct influence of light, &c. The tree knows more than 
its branches, as the species know more than the individual, 
the community than the unit. 
“‘ Moreover, inasmuch as my experiments show that 
many plants and trees possess the power of adapting them- 
selves to unfamiliar circumstances, such as, for instance, 
avoiding obstacles by bending aside before touching, or 
by altering the leaf arrangement, it seems probable that 
at least as much voluntary power must be accorded to such 
plants as to certain lowly organised animals. 
“Finally, a connecting system by means of which 
combined movements take place is found in the threads of 
protoplasm which unite the various cells, and which I have 
now shown to exist even in the wood of trees. 
“ One of the important facts seems to be the universality 
of the upward curvature of the tips of growing branches of 
trees, and the power possessed by the tree to straighten its 
branches afterwards, so that new growth shall by similar 
means be able to obtain the necessary light and air. 
“A house, to use a sanitary analogy, is functionally
