On the New Nautical Almanac. 25 



Committee having made a report of their labours, it was 

 ordered to be printed ; and a copy of the same (together with 

 a specimen of the printed pages of the new almanac) having 

 been forwarded to each member of the Committee, a distant 

 day was appointed for taking it into consideration ; by which 

 means every opportunity and facility have been afforded for 

 the most ample and open discussion of the several points in 

 question. The final result of their deliberations is contained 

 in a Report, which has been forwarded to the Admiralty: and 

 we have the satisfaction of stating that nearly the last act of 

 the late Board, was the approval of that Report, and the 

 issuing of an order for its being carried into immediate exe- 

 cution. 



We have been favoured with a sight of that Report (which 

 will form a portion of the ensuing volume of the Memoirs of 

 the Astronomical Society), and we here present our readers 

 with the following summary of the principal alterations and 

 additions. 



The use of apparent time is abolished in all the computa- 

 tions : and mean time alone adopted. 



The calculations are, in general, carried one place further 

 in the decimals than has hitherto been done : that is, all quan- 

 tities expressed in time are carried to two places of decimals 

 in the seconds ; and those in space, to one place. 



The moon's right ascension and declination are given to 

 every hour / and to the declinations are annexed the differences 

 for every five minutes. 



The places of the six principal planets are to be given for 

 every day ; and those of the four new planets for every fourth 

 day : with an ephemeris of the latter for every day, for one 

 month before and after their opposition. 



The co- efficients A, B, C, D, which are used for computing 

 the apparent places of the stars, are to be given for every day. 



The apparent contacts of Jupiter's satellites, and also of 

 their shadows, with the planet, are to be inserted. 



The lunar distances of the planets are also to be inserted : 

 with the proportional logarithm of the first difference annexed 

 to all the lunar distances. 



Predicted occultations (visible at Greenwich) of planets and 

 fixed stars, to the sixth magnitude inclusive, are to be given : 

 and also, 



Elements for predicting such occultations of the planets 

 and fixed stars, to the jifth magnitude inclusive, as may be 

 visible in any habitable part of the globe : with the limits of 

 latitude annexed, within which they will be visible. 



The apparent places of the fixed stars are to be increased
