i9o8.] OF DANIEL'S COMET. 11 



bright for some 3° or 4° back from the head. The nucleus was 

 visible to the eye as a star of about the third magnitude. The head 

 was midway in brightness between that of f Tauri and A Orionis. 

 The tail could be traced faintly for at least 15°. It was pretty faint 

 but when looked at with averted vision it could be seen fairly well 

 for a distance equal to that from ^ Tauri to Aldebaran. The end 

 of the tail just reached to BD+i5° 732 (1855.0 4'^ 56" i8^o 



+ I5°i2'.3)- 



August II. — The tail, with the naked eye, could be traced to 

 BD-|-i5° 732. The south edge would pass through that star. 

 It was 1° or i^° wide at that point. Though faint, it could be seen 

 quite well. It was straight and somewhat narrow. The nucleus 

 was conspicuous as a star-like body in the head. The head itself 

 was narrow. The tail was bright for 2° or more and then it faded 

 out rapidly towards the end. The head was as bright as ry Gemi- 

 norum. In the 40-inch the nucleus was ill defined, and blurred 

 into the brightness following. It was distinct at the preceding edge. 



August 12. — Sky first-class. With the naked eye the nucleus 

 was bright and stellar. It was about as bright as -q Geminorum. 

 The tail was perhaps a little brighter than before but rather feeble 

 except near the head. I could trace it faintly nearly to BD -|- 15° 

 732. The head was as conspicuous as y Geminorum, near and to 

 the east, but the nucleus was much less bright than that star. 



August 7j. — The sky was very thick, and part of the time at 

 first the comet was behind clouds. 



August 14. — Clouds at first covered the comet. It then came 

 out and was conspicuous about 2° east of y Geminorum. When the 

 comet and star came out of the clouds they were very much alike, 

 but as they rose higher the stellar condition of the nucleus was 

 much inferior to the star — say i magnitude less bright. The tail 

 was straight and rather slender. For 5° back of the head it was 

 pretty bright, then for the rest of its length it was faint. It could, 

 however, be readily traced to 126 Tauri (Proctor's chart). 



August ip. — It was bright to the eye — perhaps brighter than 

 before. The tail could not be traced far — perhaps nearly to y 

 Geminorum. Sky very poor.
