 Probable error of a single one of the four best results, +0-8 



The probability that this result is 10 sec. in error, is less than 0-OOOL 

 The probability that the error amounts to 25*0 sec. (the quantity re- 

 quired to include Lambert's longitude, reported to congress and ac- 

 cepted by that body) is too small to admit of computation. The high 

 authority of Bowditch, Triesnecker, Wurm, De Ferrer and Paine, 

 whose combined computations give the longitude of our prime meri- 

 dian *5'' 8" 7-0' west of Greenwich, and the demonstrable error of 

 Lambert's computations, which lead to a result of 5^ 7"" 42% as report- 

 ed to congress, leave to geographers no room for doubt as to the proper 



* In the interval between the reading and printing of this paper, Robert Treat Paine, 

 Esq., by means of three chronometers, carried by himself from Boston to Washington, and 

 thence to Boston, through Philadelphia, obtained the following important results, for the lon- 

 gitude of the Capitol.
