THE VITALITY OF SEEDS.

[TO THE EDITOR OF THE "srEc-r,troa."1 Sia,—I should like to correct a mistake which occurs in the- letters of-both your correspondents (Spectator, November 14th and 21st) on this interesting point. The place where the plant in question is found is at the Roman Camp of Cilurnum, at "The Cheaters," Chollerford (North Tyne), Northumberland. The tamp is upon the line of the Roman Wall, and large excavations were carried out there for many years by the owner of the estate, the late John Clayton, Esq. The last time I visited Cilurnum the beautiful little purple flower was growing in great profusion from the walls of a chamber. The excavator himself told me that the flower- appeared shortly after the chamber was opened out, and that it did not occur in any other part of the camp or district. I can throw no light on the botanical aspect of the matter,. but think the facts are interesting and would bear more investigation.—I am, Sir, &e.,
