Is about 8' too great. 



For 26° read 27° (misprint; Z. rigbt). 



f>W read 45' (Bonn 15. VI eoirect). 



41' read 42' (obs. in lioiin 15. VI). 



42'21".9 read 32'16". 7 (error of reduc- 

 tion in Z. 223.41). 



24°6'25".8 read 23°56'23".5. 



45^.80 n ad ■13».86 ( — error of reduc- 

 tion to middle wire iu Z. 217.80). 



37' read 38'. 



53'3S".9 read 43'37".0. 



17°44'4".4 read 16O43'57".0 (= LL. 

 34124. In tbe position of tbe Cat. 

 no star is to be seen. There is an 

 error of 1° in Z. 391.166). 



49'47".5 read 39'46".3 (also obs. in 

 Bonn B. VI). 



54' read 55'. 



38'37".3 read 28'35".l (—error of re- 

 duction Z. 220.179). 



.57' read 27' (error of Cat. ; Z. correct)- 



10'>J6''.3y read 9"'45».30 (in Z. 308.133 

 the wire should be 7, not 5). 



6'.94 read 12'.94 (error i)erliaps from 

 writing tbe time 10».0 for 16».0 in 

 Z. 240.13). 



51' read 52' (Lamont, and Bonn B. VI). 



34'20".0 read 44'21".6 (Wash. Z., and 

 Bonn B. VI). 



37' read 36'. 



42' read 44'. 



41'23".8 read 31'22".0. 



38».63 read58».63 (in Z. 244.42 the wire 



should be 4, not 5). 



To be corrected by — 10"; the preceding 



number is right, as shown by LL. 



and Lam. observations. 



An observation made at Berlin, A. N. No. 



1637, has tbe AR. smaller by lO''. 

 For 41".42 read 31'.42 (— error of Cat. ; Z. 

 right). 



20° read 29° (misprint). 



26™ read 27™ (— error of Cat. ; in Z. 

 right. The star thus appears to be 

 identical with 20632). 



84' read 35' (—error of col. 7 in Z. 

 311.82). 

 This star was not found in the sky. 

 Needs a correction of -f 10'*, or perhaps 

 of +9°. 82, the time interval be- 

 tween wires 2 and 3 in Z. 249.82. 

 For 24'. 44 read 228.44 (—error of Cat.; 

 Z. right). 



Is about 4» too small ; also in Zone. 

 For 51» read 52= (error in Z. 247.95). 



52= read 53= (error in Z. 247.97). 



52"'43" read 53"'33= (error in Z. 247.96). 



24=.83 read 34=.83 (error of Cat.; Z. 

 right). 



5' read 53' (misprint). 



26=.86 read 27».68. 



20° read 30" (misprint). 



20°4y'51".7 read 19°49'42".6. There 

 is no star in the uncorrected posi- 

 tion, and the Z. 255.23 is 1° in error. 



22"> read 21°'. 



22'" read 21'". 



56' read 51'. 



4' read 5' ( — error of Cat. ; Z. right). 



40"' read 41"' (error in Z. 245.63). 



21' read 20' (error of Cat. ; Z. right). 



59».43 read 17».63 (iu Z. 234.96 the 

 wire should be 5, not 3, which makes 

 41".80 difference). 



48».36 read 3d».07 (corrected by inter- 

 val of wires 5 and 6 in Z. 254.95, to 

 agree with Y. and Lam.). 



12=.23 read 33".09 (error in reduction 

 to middle wire in Z. 257.32). 



44'46".8 read 54'47".9 (Ham. Coll. Z.). 



29=.27 read 39".27 (error of Cat. ; Z. 

 right). 



24'" read 25™ (error in Z. 265.29). 



24'" read 25™ (error iu Z. 265..30). 



25™ read 26™ (error in Z. 265.31). 



25™ read 26™ (error in Z. 265.32). 



48'54".7 read 38'50".6. 



40™ read 41'" (error iu Z. 250.18). 



41'" read 42"' (error in Z. 2,50.19). 



45' read 47' (error in Cat. ; Z. right). 



51° read 15° (misprint). 



30'.34 read 20".34. 



19'50".5 read 59'55".2 ( — error arising 

 from a misprint in col. 7 of Z. 253.63). 



14°37'54".3 read 15°38'0".0 (iu col. 7 of 

 Z. 250.68 there is a misprint of 1°). 



2.3° read 24° (misprint iu Cat.). 



49™ read 50™. 



43'2".6 read 53'5".5. 



27'6".5 read 37'9".4. 



29'.51 read 39=.72 (error in reduction 

 to middle wire Z. 269.34). 



59'" read 60™ (error of Z. 250.100 ; also 

 the AR. of 107 and 108 of the same 

 zone, and hence No. 1 and No. 16 of 

 the Cat.o ught to beiucreased by 1'"). 



Among errors of smaller .amount, not rare is that of 1" in AR., which is more difficult to be found out. It would 

 be desirable that iu future no zone work be undertaken without the use of a chronograph, as the i)rincipal source of 

 this error lies iu miscounting the tloek-beat. Many of tlie doubtful cases have been cleared up by Argelauder him 

 self, by a reobservation, in the • Bonn B.,' Vol. VI. A few others are here appended. 



Errors of about 1= in right ascension.
