ir)'2 Mansfield Merrhnan — Lixt of Writings relating 



In prejiuriiig this list I have been able to use only the libraries of 

 Yale College, (including that of the Connecticut Academy of Arts 

 and Sciences,) but I think no work in those libraries relating to the 

 subject has been left unconsulted. Out of the total 4U8 works, I 

 have seen 812 ; the titles of these and the accompanying notes have 

 been drawn from actual inspection. T have made uo attempt to con- 

 sult the literature of the Russian and Hungarian languages, and with 

 wider library facilities the number of titles in the Italian, Dutch and 

 Scandinavian languages would undoubtedly have been greater. Of 

 course no work of this kind can be regarded as complete. 



It has been my aim to record all Avritings which can be considered 

 as contributions to the science of the Adjustment of Observations, and 

 I think that those marked as actually inspected may be truly so 

 reo-arded. Many works on Astronomy and Probability which devote 

 but a page or two to the subject, as well as numerous ]>ractical 

 papers, in which the Method of Least Squares is used incidentally 

 and briefly, have been left unnoticed ; to record all of these would 

 be Avell nigh impossible, nor would the value of the list be thereliy 

 increased. Among the 96 which I have not seen there may possibly 

 be a few that woidd be rejected after actual inspection. 



The following is the arrangement of the list. 



At the head of a title is placed the year of publication. In the 

 case of memoiis this often difters from the date of the vohime in 

 Avhich they are contained ; for instance. Nautical Almanacs are pub- 

 lished several years preceding and Transactions of Learned Societies 

 often several years after the date which they bear. When a memoir 

 is ])ublished in parts extending over two or more years it is recorded 

 under the date of the first part. 



The author's name follows the date of publication. In the index at 

 the end of the list the full names of authors are given, and a distinc- 

 tion is made in the text when two persons of the same surname have 

 written on the subject. 



The titles of books, and pamphlets published as books, are printed 

 in Italics, and the titles of memoirs in ordinary type. Those which 

 I have actually inspected have their titles enclosed in single quota- 

 tion marks (' ') and these are intended to correspond with the 



originals in punctuation, spelling and when possible in the use of 

 capitals. 



The place of publication of books is given, with references to sub- 

 sequent editions or translations. The usual terms 4to, 8vo, etc. are 

 added, although they give little idea of the size of a book, and the
