OBSERVATIONS OF LUNAR OBJECTS. 85 



Interval 144 to 132 hours. 



1871, March 8. Mr. Ormesher records a spot near the S.W. border, 

 ■which he queries " 14, a long way off " from its position. Is it a spot not 

 before recorded ? 



1870, August 13. Mr. Gledhill records spots Nos. 3 and 17 as fine bright 

 disks. No. 1 as a fine, largo, bright disk, and No. 4 as a nebulous object. 

 Mr. Pratt remarks that " on this evening, as ivell as in 1870, August 12, 

 the tint of the dark portions of the floor was much intensified close to the 

 rim. It was the case all round, but especially so between 6 and ^, between 

 e and ^, and between /3 and rj." 



1869, December 20. Mr. Pratt places a spot nearly due north of No. 1 

 on the diagram of this evening, wliich he queries as 23. I query it as un- 

 certain. Spots Nos. 1, 0, 23, and 16 very nearly align. The line passing 

 through Nos. 1, 0, and 23 passes slightly west of No. 16. Mr. Pratt's spot 

 is very decidedly east of this line. [1871, March 31. The spot registered 

 by Mr. Pratt on Dec. 20, 1869, not having been reobserved, it is probable 

 that it may have been, as Mr. Pratt queried, No. 23. I have now entered 

 it as such.— W. R. B.J 



Interval 132 to 120 hours. 



1870, September 12. Mr. Neison records of No. 22, " a spot very faint, 

 and difficult to make out in the midst of a patch of light." 



Interval 108 to 96 hours. 



1870, July 16. Mr. Gledhill records spot No. 1 as "a fine, large, bright disk; 

 looks like an elevation ;" also Nos. 3 and 17 as bright disks. I have made 

 the following note on the Form : — " 9 and 0. These do not appear in their 

 precise localities, especially 0. It may be that the spot thus marked by 

 Mr. Gledhill is a new one." 



1870, December 12. Mr. Pratt writes : " A faint crepusciilar kind of 

 shade has crept over the western part of the floor, and is deepest near the 

 western border ; but the gradation is very delicate, 12 hours to 12 hours 40 

 minutes." [1870, March 24. Mr. Gledhill noticed a darker tint at the west 

 part of the floor, and furnished a tinted sketch : see remarks under this 

 date (p. 87) ; also Mr. Elger's observations of the same portion of the floor 

 being light, under date 1870, August 6, interval 48 to 60 hours.] 



1870, November 11. Mr. Gledhill records spots Nos. 1, 3, 30, and 17 as 

 brk/ht S2)ots. On the 13 of September (same interval) he recorded them as 

 "bright or fine craters;" with the exception of Mr. Nelson's record on 

 August 12 of No. 3 as a suspected crater (interval 168 to 156 hours), this in- 

 terval (108 to 96 hours) is the earliest in the declining day that the four have 

 been seen as craters. The terminator is recorded as west of Fracastorius. 



1870, September 13. Mr. Gledhill records spots Nos. 1, 17, and 30 as 

 bright or fine craters, and says of 17, " fine crater as 1 and 3; " but of 3 

 he says, " fine disk." I have marked 3 as a crater. 



Interval 96 to 84 hours. 

 1870, August 15. Mr. Pratt records that the darker margins of the 

 sbiided parts of the floor are still visible as on the 12th and 13th August, 

 but not in such striking contrast. 



1870, October 13. Mr. Pratt records spot No. 1 as brilliant, the others 

 dimmer than usual. 



Interval 84 to 72 hours. 

 1869, August 26. Mr. Pratt remarked a decided difference in definition
