The twist in the tail was quite prominent, and the forked appearance was 

 distinct. Ou the 19th there was but little change to be seen. The next 

 morning the tail appeared shorter and broader, the twist not prominent, and 

 the end more even. The nucleus was decidedly less brilliant. Ou the 21st 

 the tail was broader. Ou the 22d the coma and nucleus showed unmistak- 

 able signs of being smaller and fainter. The tail was much the same as on 

 the two previous days. Ou the 23d the tail was much broader near the end 

 than anywhere else. The end was but slightly uneven. The head was small. 

 Oo November 5lh the comet was much less brilliant than on former days. 

 Nucleus was small but brilliant. Tail was much broader than before, and 

 brightest along the south edge from the head to the middle of its length. 



TELESCOPIC OBSERVATIONS. 



On October 9th the nucleus was granular and elongated in the direction 

 of the tail. Along the north side of the coma, between 20' and 25' from the 

 nucleus, and running parallel, or nearly so, to the center line of the tail, 

 there was a faint streak of light quite distinctly bounded on the north side, 

 but fading gradually away toward the comet proper. The brilliancy was 

 not greater than that of the tail at its apparent termination. This faint 

 streak of light extended toward the sun fully one-half a degree from the 

 nucleus, but its end was illy defined. Ou the south side of the coma there 

 "was a similar but fainter streak of light about 15' from the nucleus, parallel 

 to the axis, and extending 15' toward the sun. Both of these streaks ex- 

 tended westward from the nucleus until they met the tail, where it was broad 

 enough to equal the distance between them. Ou October 13th the streaks 

 were apparently a little longer in the direction of the axis, but were at the 

 same distances from the nucleus. The haze between them extended across 

 in front of the nucleus. The brighter part of the tail was enveloped in a 

 thin haze, and the streaks were a forward continuation of it. On October 

 14th the eastern haze was longer and brighter, the sides were decidedly par- 

 abolic in form, but the eastern end was poorly outlined. Ou the 15Lh the 

 appearance was much the same, though the haze was longer and broader. 

 It was quite uniform in texture, and faded away gradually toward the east. 

 By the 17th the brightness of the haze had become less, though the size re- 

 mained nearly constant. The edges were brighter than the central parts, 

 and extended in the form of two short, straight horns. On the 20th the size 

 was about the same, but the edges were more nearly straight, the eastern end 

 was very poorly defined, and the brightness very much reduced. Ou the 

 21st, 22d and 23d the haze gradually lost its brightness, but the size remained 

 about the same. It was last seen on October 25th, when it was exceedingly 

 faint, and presented nearly the same appearance as when it was first seen on 

 the 9th. The observations on the decrease of this haze seem to show that it 

 became invisible through the lessening of its light, rather than by a dimi- 

 nution of its size.
