U. S. COAST AND GEODETIC SURVEY. 



In finding the difference between the longitude of the time meri- 

 dian (S) and the longitude of the place (L) consider west longitude 

 as positive and east longitude as negative. 



In the ordinary use of Form 244 it is assumed that civil time has 

 iDeen used in the tabulations of the observations. If, however, the
