SCIENTIFIC SUMMARY.

parallel. I failed to find tlie red star on February 6, 1873, and was informed 
by Mr. Knott, to whom I communicated my failure, that he was equally 
unsuccessful on two previous occasions — on June 25 and August 3, 1866, 
However, on January 13 of the present year, I found a star in the position 
of 101, as well as I could identify it in a hurried observation. The passage 
of clouds did not permit me to examine it very closely, but it appeared 
about the 8*5 magnitude, and slightly tinged with red. I have not observed 
it since then ; but I would suggest that it should be closely watched in 
its present excellent position for observation, when its very probable varia- 
bility might be determined. 
“ In No. 74 1 have remarked differences within the limit of one magnitude, 
with considerable changes of colour : Schjellerup thus notes it — Bessel- 
roth, Cape Obs., vivid red, 8. 
“ My observations of it were as follows : — 
“ 1871, March 8. Pale red, 8. 
“ 1872, Feb. 10. Orange, 8. 
“ 1873, Feb. 2. Orange, 7-5 to 8. A comes 9-5 ; intense blue ; 285°. 
“ 1873, Dec. 20. Fine orange red, 7. 
“ 1874, March 6. Fine orange red, 7. 
“No. 77, described by Schjellerup as roth, 7*7, seems less than 8, withthe^ 
palest possible red tinge. 
“ It may not be out of place here to refer to a very remarkable orange star ~ 
which I found when looking for 77. On February 2, 1873, it appeared 
about the 7th magnitude, with a comes of the lltli ; position 95°. On 
December 26 the large star seemed of the 6th magnitude. On February 3 
it looked nearer the 5th, and on March 8 it appeared of the 6th magni- 
tude again. Its roughly approximate place by equatoreal is R.A.,, 
6 h 14 m 40 s , Decl. -2° 54' 30". Its small apparent changes may, indeed,, 
be due to errors of estimation ; but I consider it worth the attention of' 
observers, as it is strikingly superior in depth of colour to very many of the 1 
stars in Schjellerup’s Catalogue ; and the fact that it was missed by 
previous observers of red and orange stars is strongly suggestive of 
variability. From recent measures, I find that the angular distance of 
the comes is 100", and the position 99°. 
“No. 63, unless I mistake its identity, presents an instance of complete 
change of colour. It appears as one of Schjellerup’s own stars in the list, 
where it is marked ‘ roth/ but to me it always shows a fine blue tint ^ 
while 51 Orionis , near it, is deeply orange. 
“No. 152, which is described in the Catalogue as a red star of 8-5 magni- 
tude, has been observed by me on several occasions as a fine orange star of 
the 6th magnitude. 
“ No. 280 furnishes an undoubted instance of change. It is catalogued as 
one of Argelander’s stars of the 6th magnitude, and followed by a blue star 
on the same parallel. On April 18, 1873, I noted it as a good red, but no 
more than 7’5, and estimated the blue star at the 9th magnitude. On 
January 15, 1874, the red seemed only of the 8*5 magnitude, and it was 
considered even smaller by the Kev. Mr. Webb, on the 12th. On February 
17, I thought the star had risen to the 7th magnitude, with a high colour.”
