STARS IN COMA BERENICES. 355 



the conclusion at which I arrived in each special case, and in ac- 

 cordance with which the correction was applied in the succeed- 

 ing calculations. The numbers refer to the catalogues detailed 

 in Sec. I. 



(i) The proper motion given is used in the reduction. 

 See pp. 1 8 and 20 of the introduction. 



(2), (3), (4), (5) These do not take account of proper mo- 

 tion. In (3) and (5) it is not mentioned ; in the case of (4) 

 see Introd., p. 26, §11; and for (2) see Argelander's Bonner 

 Beobachtungen, Vol. VII, p. 10. 



(6) No proper motion is applied unless a ^ is found in the 

 column headed " Epocha Media." Its value, although not 

 given, may be obtained from the value for Str. — Bradley, 

 given pp. 299 ff See Introd., p. lxxx. 



(7) Pond uses the A. S. C. constants and no proper mo- 

 tion unless therein included. Such cases are marked by an 

 asterisk in the column of precessions, the same as in the 

 volumes from which the constants are copied. 



(8) Proper motions greater than o" .^ are always, and those 

 greater than ©''.25 are sometimes included in the reduction. 

 Smaller values are always neglected. Introd., p. 2. 



(9) No stateinent. Proper motion is probably not taken 

 into account. 



(10) According to Introd., p. xxviii, proper motion is not 

 used in the reductions. 



(11) Proper motion is neglected in reducing the observa- 

 tions to the beginning of the year, except where included in 

 the A. S. C. constants (Introd., p. xxiv) ; but in combin- 

 ing the separate annual results into a general catalogue, it is 

 taken into account (p. 595, " Column 6") whenever its value 

 is given. 



(12) See (26). 



(13) This catalogue does not take account of proper mo- 

 tion. As it was not accessible to me, I could not personally 

 verify the above statement, which is made in accordance with 

 Davis, p. 28, no. 69. 



(14) I could not find any definite statement bearing on
