1873 Jordan. ' Verallgemeinerung eines Satzes der Methode der 

 kleinsten Quadrate.' Zeitsclir. Math. v. Phgs., Vol. XVIIT, pp. 

 116-120. 



Concerning the solution of normal equations. 



1873 JouFRET. Syr la methode des moindres car res et ses ajyplica- 

 tions du tir. Paris, 8vo. 



1873 Laurent. ' Traite du calcnl des lyrohahilit'es!' Paris, 8vo. 

 pp. xii, 268. 



This is intended as an introduction to the study of Laplace's 

 Tli'eorie. . . . des Proh. At the end is the best list of literature on the 

 Method of Least Squares which I liave seen. 



1873 Nevvcomb. 'A mechanical Re|)resentation of a familiar 

 Problem.' Monthlg Notices Astron. Soc. Lorid.., Vol. XXXIII, pp. 

 573-574. 



" Given at several epochs, observed values of a quantity which 

 varies uniformly with the time, to find by Least Squares the most 

 probable values of the two constants which fix its value at any time." 

 The analogy of the question with one of equilibrium in mechanics is 

 pointed out. The solution of a system of linear equations by Least 

 Squares may be represented in a similar way. 



1873 Peirck (C. S.) 'On the theory of errors of observations.' 

 Eep. Coast Sitr. IT. S. for 1870, pp. 200-224. 



Gives an account of some interesting experiments " made to study 

 the distribution of errors in the observation of a phenomena not seen 

 coming on, as in the case of a transit, but sudden as in the case of 

 the emersion of a star from behind the moon." The results are given 

 graphically and show a decided approximation to the ex])onential 

 law of facility. 



In the ten pages of introduction new ideas are offered concern- 

 ing a notation, " suggested by the study of the logic of relations." 



1873 Seeliger. ' Ueber die jAconi'sche Auflosung eines Systems 

 von Normalgleichungen mit drei Unbekannten.' Astron. Nachr., 

 Vol. LXXXII, col. 249-252. 



See above 1840 Bessel. 



1873 Stone. ' On the most Probable Result which can be derived 

 from a number of direct Determinations of Assumed Equal Values.' 

 Month. Not. Astron. Soc. Load., Vol. XXXIII, pp. 570-572.
