^{page 336 note †} Since this paper was read, Lieutenant Pettersson has kindly verified my calculation, and assigns, as the position of my station, lat. 57° 42′ 58″·0 N., long. 0^h 47^m 45^s·3 E.

^{page 336 note ‡} As the value of the following observations must depend greatly on the character of the instrument with which they were made, I may mention that this telescope shews bright stars, with perfectly round, well-defined discs; and, with a power of 75, the two stars in Castor are seen completely separated.

^{page 336 note §} To Professor Chevallier, and especially to Lieutenant Pettersson, my warmest thanks are also due, for their kind assistance and advice.

^{page 338 note *} The chief inconvenience I found in using this instrument, arose from being obliged to point the telescope by the hand. A slow rack motion would have been very useful. In observing a total solar eclipse, every moment is so valuable, that too much care cannot be bestowed beforehand in having everything adapted to save time. From my own experience, I should recommend observers to have their telescope mountings as commodious and firm as possible.

^{page 339 note *} Shakespeare makes Hecate say:—

—Upon the corner of the moon

There hangs a vaporous drop profound.”

This odd fancy forms no unapt description of the rounded appearance of the cusps, which certainly looked very much as if a drop of liquid were depending from them.

^{page 340 note †} The nearly instantaneous appearance of these lines vividly recalled a well-known passage of Coleridge's,—

—that strange shape drove suddenly

Betwixt us and the sun,

And straight the sun was flecked with bars——”

^{page 341 note *} It may be proper to mention that my vision is rather highly myopic, and that I can read with less light than most persons.

^{page 344 note *} If this experiment be ever repeated, it should be performed in an apartment, or by means of a box adapted to exclude the general light of the atmosphere. The candle should be carefully preserved in order to compare its light with that of the moon.
