ACCOUNT OF THE METEOR SEEN IJT CONNECTICUT. 



The course from S to M is nearly N 15* V/, the distance 

 SM 4' 29''; hence the difference of latitude of the points S, 

 M is 4' 20", departure 69*6', difference of lonjritude 93". 

 Hence the latitude of the point M is nearly 4ri9'20'N, ' 

 and its longitude 73"28'33".W. 



If it be required to find the change in the above elements 



arising from an errour in the altitude at Wenham, it would 



only be necessary to repeat the latter part of the calculation, 



since the values of SA, SWA, AWB, would remain the 



same in both rases.
