(Proc. n. Geogr. Soc. 1879, p. 568.) 

 Mr. Ball has, however, not confined the Table to the local problem. He has traced 

 out the distribution of each species of the Alpine flora in the other mountain-ranges of 

 Europe. The usefulness of this feature of his work to those who study geographical 

 botany must at once be obvious. The result was to confirm him in his belief that the 

 Alpine flora owed comparatively little to a migration from the Arctic flora. In this 

 respect he seemed somewhat alarmed at appearing to come into conflict with the views 

 of Mr. Darwin and of Sir Joseph Hooker in tLe well-known classical paper by the latter 

 published in the Transactions of this Society. But, as Sir Joseph Hooker very properly 

 pointed out, " neither Mr. Darwin nor Professor A. Gray nor bimseK had ever dealt with
