being inclosed in a parenthesis and separated by a dot; the declinations, taken from the special 

 lists and reduced by means of the equations just given to the standard of Bessel for northern, 

 and of Argelander for southern stars ; the mean of the right-ascensions to the nearest second, and 

 for the declinations the rigorous mean by weights ; and lastly, inclosed in brackets, the sum of 

 the several partial weights for the declinations. The factors for the several authorities, which, 

 when combined with the number of observations, constitute the partial weights, are :
