284 REPORT— 1872. 



spot No. 4. He has not mentioned it before. Mr. Elger gives /3 with the 

 Bpot No. 32, discovered by him this evening." Mr. Gledhill's record of the 

 remaining streaks observed by him is as follows : — " e and i bright, broad ; 

 a, P, y, S fairly bright ; ^ extends up to spot No. 4 ? ; e extends as far north as 

 ^." He agrees with Mr. Elger in recording the " streaks as brighter than 

 last night," the 14th. He does not mention the sector ; but I suppose he saw 

 it. In speaking of ^ extending to spot No. 4, does he refer to rj ? 



1870, October 6. — Mr. Gledhill recorded the floor as medium, = 0-50 ; the 

 streaks very bright. Mr. Elger, the same evening, -p. , . 



described them as all faint, especially on the east ^^' 



side of the floor. Webb's elbow and c he de- « ^ 

 scribed as plain : a sketch is given of the junction 

 much the same as it was seen on August 11, 1870 

 (interval 168 hours to meridian, see fig. 18, post, 

 p. 289) ; the western strip of light on the floor 

 appears to have subsided since October 4, as ob- ^^'^^' ^^^- ^■—'^- ^- ^- ^^ger. 

 served on May 10, compared with May 9, 1870 (see mite, pp. 273 & 277). 



^Mmmaj-^.— Sun's altitude 28" 54'-3 to 31° 42'-7; tint of floor 0-54, esti- 

 mated from curve. Streaks generally visible — sector, trident, and N.E. streak. 

 The trident with stem was seen complete by Mr. Pratt on March 14, 1870. 

 The streak n, which is very rarely seen indeed, was observed on April 12, 

 1870, and also on March 3, 1871. The streaks were mostly bright. 



Interval 108 to 120 hours. 



1870, May 12. — Mr. Elger recorded the sector and streak y as very bright 

 and well defined; ft brightest near spot No. 3, and faint at border. The 

 three arms of the trident, ^, e, e, faint, but easily traced ; the floor noted aa 

 very dark between e and e. The projection from Webb's elbow, c, seen 

 during the April lunation, although plainly seen, could not be traced so far 

 to the south as before, and was not so sharply defined ; indeed all the west 

 portion of the N.W. marking (i.e. the brightness in the N.W.) was hazy. 

 [Haziness on the W. and N.W. part of the floor was noticed on April 11, 

 1870, by Mr. Elger. On April 12, 1870, by Mr. Pratt, who described it as 

 very hazy. On June 10, 1870, by Mr. Elger.] The streak a east of spot 

 No. 16 was very bright and well defined, and Webb's elbow was very 

 evident. The localities of spots Nos. 33 and 35 were the brightest. On the 

 same evening and interval, Mr. Pratt described the sector as but faintly 

 seen, and with the very same aspect as his first view of it, viz. a streak 

 sloping more N.W. and S.E. than usual, its western edge quite straight, its 

 eastern edge slightly curved and fan-shaped ; all' other streaks invisible. 



1870, January 14. — Mr. Elger writes : — " The markings were at times 

 very distinct, the east portion of y unusually so. I was unable to make out 

 Webb's elbow. The streaks ?;, ft, y, the sector, and trident were aU di- 

 stinctly seen. I much regret that the long speU of cloudy weather prevented 

 me from observing the markings after the 14th instant, as I think those on 

 the east side of the floor (y, »;, ft) were visible much sooner after the first 

 quarter during this lunation than they were during the last. [Had they 

 become brighter ? See Interval 96 to 108 hours, 1869, December 15, ante, 

 pp. 282-284.] There appeared also to be something abnormal about spots 

 Nos. 1, 3, 4, 5, and 17. Spots Nos. 6, 24, &c. I was unable to make out, 

 although they were seen on the 14th of December, 1869. 



1870, September 7. — Mr. Gledhill recorded the floor as dark, =0-66; 

 streaks all veiy bright.
