 tortion of the moon's limb could be seen, and the cusps of the sun, 

 before the ring formed, were as sharp as needles."

" At beginning of eclipse, limbs sharp and well defined. The 

 same at formation and rupture of the ring, only in ^the former the 

 light seemed to flash round the moon's limb." Two detached arched 

 portions of the ring were seen separated from the cusps, " while 

 the space l)etween presented points of light (beads) only."

Arch of faint light with brush in centre, seen before the forma- 

 tion of the ring. Arch seen after rupture, brush of light not recol- 

 lected. Formation and rupture of the ring, by broken portions of tho 

 sun's border, several in number, not round like beads, but arched 

 portions of the ring. These continued several seconds, and then 

 suddenly united in the first instance, and separated in the last, 

 without, however, exhibiting the dark lines figured by Baily.
