No. VI.—SOLVITUR AMBULANDO
On this chequered floor, paved with slabs each a foot square, the palindrome word ROTATOR can be traced in various ways.

No. VII.—A CURIOUS CHRONOGRAPH
A bachelor clergyman, whose initials were I.E.V., had built a fernery with the profits of his tracts on the deceased wife’s sister question. He dated it on a mural tablet thus:—
| My LateVVIfe’ssIsterbVILtthIs VVaLL; bVT I In trVth neVer VVeD any VVIfe at aLL, nor VVont forsooth, saIth I. e. V. | ||
If the Roman numerals are extracted from this inscription, and added together, they amount to 1884, the desired date.
