tion outwards, nearly three digits ; cusps distant 30° on sun's limb, 

 a broken point or bead at each end. This phase noted as that of 

 the formation of the ring by Nos. 1, 2, 3, 4, and 1 1 . 



D. Formation of ring or instant of osculation of limbs. This 

 phase noticed as the approach of two sharp well-defined points to 

 a contact, by Nos. 5, and 15. It was observed at the instant when 

 the cusps, apparently 20° of the sun's limb apart, suddenly united 

 by the extension of four or five luminous beads, or rounded portions 

 of the sun's disc, by Nos. 3, 4. 8, 9, 10, 11, 13, and 14. 



E. Omitted in the table. This letter refers to the time when 

 the dark lines, described by Van Swinden and Baily, should have 

 appeared. They were not seen by any observer, though carefully 

 searched for. 



F. Perfect ring, the beads of light having united, or run into each 

 other suddenly. 



G. Counterpart of E, not observed though looked for. 



H. Rupture of ring, counterpart of D. Took place at a point 

 and so noted by all the observers. 



I. Appearance of beads, five or six in number, extending from 

 cusp to cusp. 



K. Counterpart of C, in every respect. 



L. Counterpart of appearance just preceding C. Brush or blaze 

 of light, narrowed down to a small space, 3° or 4° on the moon's 

 border, extending outwards 2^ digits ; cusps still broken as seen by 

 most of the observers. Nos. 5 and 15, however, saw no irregularity 

 of cusps, no beads of light. 



M. Final disappearance of arch of faint light, with brush of light 

 extending beyond the middle, having previously become very faint. 

 This phsenomenon observed with great care and certainty by No. 10. 



Doubtful.
