to 168°. Looked again for nebulous object seen Nov. 3.7. It has 

 not moved. It is likely a nebulous star — a glistening point of light 

 is seen from time to time in its centre. 



Nov. 7.7. — Again tried method of search by recognition of disk. 

 Improved by having dome all dark. I set with tangent screw in decli- 

 nation upon successive narrow zones, and sweep in R. A. Used 

 power 600. Success good — shall try this method further. Clouded 

 over between 16 and 17 hrs. 



Nov. 11.7. — Swept carefully between 9° and 10° of my plan of 

 to-day. Used power 600. 



An object suspected, -\-'d° 45'. 



Object is c. aS=24^± 



ac = 74' ± 

 R. A. 10^ 19™ ± 

 I do not much believe it to be anything but a star. 



Examined again, Nov. 13.7. Object a star. 



An object a about equally suspected, -|- 9^ 35', R. A. = ll"" 1" 

 It has a faint comjmnion, p = 96°, s = 25". 



ab = 12'.5. c is bright star and 2'± south of parallel of b. 



Examined again, Nov. 13.7. Object a star. 

 Twilight, however, prevented my seeing 

 the comes. 



Iris ® Nov. 11. a = 3" 43'", S = + 24° 5G'. 



After it began to be pretty light (about 17''.5), I tried search by 

 clamping in R. A., and sweeping in declination, following my adopted 

 plane of the planet's orbit. 



Set on 8 = +6°.5. 

 a=: 11'' 12"'.
