St. Piran's, is sunk below the level of the surrounding cemetery, and it has a division running across it, to mark the limits of the nave and chancel, the former of which measures 15 ft. in length, and the latter only 5 ft. The altar is of stone, and a bench of stone is built along the walls all around the interior. There is a small window in the south wall, measuring about 1 ft. 3in. in width, the arch of which is destroyed; and opposite to this window is the doorway, in this instance placed on the north side; it measures 2ft. 10 in. in width, and the head of this is also gone.

Though this writer seems to despise the efficacy of these waters, the tradition of their virtues still remained amongst the Cornish: only a century ago, a writer describing the gene-
