Notes on the British Association Catalogue of Stars. 
By W. S. Jacob, Director of the Madras Observatory. 
The catalogue of 8377 stars published by the Association in 1845, though com¬ 
piled from the best data available at the time, is, as regards the places of many 
touihern stars, erroneous, owing to the imperfect nalut e of the data, especially those 
depending on Lacaille and Brisbane. 
A thorough revision of the catalogue was therefore commenced at Madras in 1849, 
end completed in 1853, by observing, in most cases, at least three times with both 
'•aiuit ami mural circle, every number to which any doubt attached between the 
N. I'.D. 40° and 156°, and in a few cases a little beyond these limits. 
The subsidiary catalogue thus formed has been printed in tbe last volume of 
Madras Observations,' which should etc now have been on its way to the India 
fienw. 
Hie general results of the revision may be briefly stated as follows -I nail, 1503 
timbers were examined; of these the undermentioned 55 were missing, viz.:—
