SeSlJon of our fidereal fyjienu 



By taking out of this table the vlfnal rays which anfwcr to 

 the gages, and applying lines proportional to them around a 

 point, according to their refpeclive right afcenfions and north 

 polar diftances, we may delineate a folid by means of the ends 

 of thefe lines, which will give us fo many points in its fur- 

 face ; 1 Ihall, however, content myfelf at prefent with a fec- 

 tion only. I have taken one which paflcs through the poles of 

 our fyftem, and is at re6tangles to the conjunction of the 

 branches which I have called its length. The name of poles 

 feemed to me not improperly applied to thofe points which are 

 90 degrees diftant from a circle pafling along the rnilky way, 

 and the north pole is here affumed to be lituated in R,A. 186^ 

 and P.D. 58°. The fe6tion reprefented in fig. 4. is one which 

 makes an angle of ^^S degrees with our equator, c roiling it in 

 124I and 3041 degrees. A celeftial globe, . adj ufted to the lati- 

 tude of 55° north, and having a- Ceti near the meridian, will 

 have the plane of this fedlion pointed out by the horizon, and 

 the gages which have been ufed in this delineation are thofe 

 which in table I., are marked by. afleriiks. When the vifual 

 rays anfwering to them are taken out of the fecond table, they 

 mufl:' be proje6led on the plane of the horizon of the latitude 

 which has been pointed out ; and this may be done accurately 

 enough for the prefent purpofe by a globe adjufted as above di^ 

 reeled; for as gages, exadlly in the plane of the feclion, were 

 often wanting, 1 have ufed many at lome fmall dllfance above 

 and below the fame, for the fake of obtalninf7 more delineatino; 

 points ; and in the figure the flars at the borders which are 

 larger than the reft are thofe pointed- out by the gages. 1 hi
