Tide Tables.—Can you, or any of your subscribers, give me a rule for ascertaining the heights of tides and times of high water, the establishment of the port, and rise of springs and neaps, being known? One divested of algebraic formulæ would be preferred: say—
| Establishment | 10 h. 58 m. |
| Springs' rise | 8½ feet. |
| Neaps'" | 2 feet. |

Passage in Ovid.—In speaking of the rude and unscientific state of the early Romans, in the third book of his Fasti, Ovid has the following verses:
"Libera currebant, et inobservata per annum
Sidera: constabat sed tamen esse Deos.
Non illi cœlo labentia signa tenebant;
Sed sua: quæ magnum perdere crimen erat."
