My obsei'vations are: — March 27, 1875, about 7iin; January 19, 

 1876, 11 or 7i; February 10, 1877, a little less than a star sp X 

 and fx Ursse llajoris ; February 21, 1884, about 7 m — considerably 

 less than 43 Camelopardalis ; also less than 17 Leonis Minoris. 



ISo. 297. 12 Sestais-tis.— 6 ni. Lalande (19542); 6-7 Heis ; 6-5 

 DM; 6*8 Gould, who found it 6"1 at Albany, but the Cordoba esti- 

 mates were 6-7 to 6" 9. 



February 18, 1877, I found it brighter than LL 19473 (6 m.). 



This latter star is not in Sarding^s Atlas; I estimated it 6|-m. on 

 the above date (and brighter than 9 Sextantis) ; March 7, 1884, I 

 estimated 12 as 6-8 m, ; April 2, 6"8 -less than 13, but brighter than 

 LL 19473. 



^0. 298. 3428 B.A.C. HrDEiE = LL 19634.— 7 m. Lalande; 6-7 

 Heis ; 7^ Franis, " deep dull yellow." March 2, 1878, Dr. Gould says 

 it is not brighter than 7*m. (Z7. A., p. 303) ; April 7, 1883, I esti- 

 mated this stai' 7*2 m. 



It is 6-7 m. in the Cape Catalogue (1879"17). 



T^o. 299. Laxanbe 19662 Sestajs^iis. — 4^ Lalande; 5m. Harding; 

 7-8 Lamont (1845); 6-7 Heis. It does not seem to have been ob- 

 served by either Argelander, d'Agelet, Bessel or Santini {Nature, 

 May 13, 1875) ; Gould gives it 6-4 in the Uranometria Argentina. 



In April, 1875, I found the star only 7 m. 



February 15, 1877, less than 17 Sextantis (6-7 Heis). 



Febmary 11, 1880, less than 17 Sextantis. 



April 7, 1883, estimated 6im. 



Xo. 300. y I. 163 Sextantis. — A nebula observed by Admiral 

 Smyth, who says {Bedford Catalogue, p. 224), "It is remarkable that 

 this object was very clearly distinguished in my telescope ; for H. 

 says it was scarcely perceptible in his twenty-foot when he gave it 

 only six inches of aperture." According to Chambers it was " seen 

 without the sligtest difficulty in a finder of 2^ in. by Brodie." 



IS'o. 301. v^ Hydi'se. — 5 m. Lalande and Harding ; 5-4 Heis ; 5 m. 

 Franks, and = v^ Hydi'^, March 2, 1878 ; 5-6 Cape Catalogue (1879-19). 

 The Cordoba estimates vaiy from 4-5 to 5*2. 4-69 H.P. 



March 28, 1876, I found v^ about ^ mag. fainter thanv^ Hydrse. 



April 7, 1883, v^ four steps fainter than v^. 



April 8, 1883, v^ one step less than k Hydree, and four steps less 

 than uK 



1^0. 302. Lacaille 4174 Caehs^^. — 7 m. Lacaille ; 6^ Brisbane; 

 7 m. Cape Catalogue (1875*26). It was found generally below 7'0 m. 

 at Cordoba, and Gould considers it ' ' variable by not less than half a 

 unit."
