In the star list which follows the coordinates of those stars found in Newcomb's 

 Fundamental Catalogue* were taken from that publication, but were reduced to the system 

 of Auwers. The declinations of the remaining stars were deduced from what, is believed to 

 be practically all existing material, including observations made at the Lick Observatory, 

 kindly furnished in advance of publication byll. H. Tucker. The reduction to Auwers' 

 system has been applied in all cases where such was available. In case of a few of the 

 newci' series where this relation had not been investigated the Catalogue places were 

 employed directly, but with a somewhat diminished weight. 



It- is not to be inferred that the system of Auwers is considered superior to that of 

 Neweomb, but as Ibis is the system more; generally used in latitude work of Ibis character, 

 its employment here renders the results more directly comparable with those obtained 

 elsewhere (ban would otherwise Ik; the case. In the two pages which follow are found the 

 mean coordinates for L875, with elements of reduction to any epoch which appear to call 

 for no explanation. The numbers are those of the British Association Catalogue. Those 

 stars marked N were taken from Newcomb's Catalogue. 



This list is followed by a, second, giving the mean places for L894 and 1895. The 

 reduction to apparent place is as follows: 



j c,s + «!') = $ (,j„ + <y) + i (/<' + i>\) - + I («'+ "'.) ■* + i ('>' + b 'i) B + h («' + «'i) 0+ i (d< + d\) i) 



h and <V being the apparent declinations required, 

 <\, and <V the mean declinations here given.
