"The ring formed instantaneously, and broke nearly so. No 

 beads were seen, nor the dark lines mentioned by Mr. Bailey, nor 

 the light round the moon, although all were looked for. No distor- 

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

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



No. 17, by Lieut. Gilliss, U. S. N., at the Marine Observatory, 

 Washington City, N. 8", W. 0.08s in time, from the Capitol, with a 

 3^ feet achromatic, green screen glass, power 50. Astronomical 

 clock regulated by a five feet transit instrument.

Do. of ring, 



" 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 por- 

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

 space between presented points of light (beads) only."
