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 11. 



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 Bailey, should have 

 appeared. They were not seen by any observer, though care- 

 fully 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 G 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 ir- 

 regularity 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 phenomenon observed with great care and certainty by No. 

 10. 



N. Appearance o^ dark lines extending into the sun's disc, noticed 

 by Nos. 3, 4, 10, and 14. The time noted by Nos. 3 and 14 as 

 the end of the eclipse. 



O. End of eclipse, inferred by each observer from his notes. 



P. Final disappearance of the dark lines, the sun's disc having re- 

 sumed its natural shape. Nos. 3, 4, 10, and 14 inferred the 

 time of O as at some instant intermediate between N and P. 

 The time of external contact difficult to determine, on account of 

 this irregularity.
