lide of the Wilder. The naked eye then will immediately dire£t 

 us, by means of the two ftars juft mentioned, towards the 

 place where, in the finder, the armed eye will perceive the 

 double flar in queftion about | degree from the 44th Lyncis. I 

 need hardly obferve, that we mull: recoiled the invcrfion of the 

 finder, as thofe who are in the habit of ufing teiefcopes with 

 high powers, always fnrnifhed with inverting finders, will of 

 courfe look for the fmall ilar in the upper part of the field, as 

 in fig. I. ^ 



At the 45th ftan, in the fird clafs, the defcription fays, 

 *^ About I \ degree f. preceding ^ti, towards ; Aurigse.'* This 

 double flar will accordingly be found by placing ^ Aurigae firft 

 into the center of the finder ; then, drawing the telefcope 

 towards/, which the naked eye points out, the ftar we look for 

 will begin to appear in the circumference as foon as jtt is about- 

 I degree removed from the center, as in fig. 2. 



It will fometimes happen, that other flars are very near 

 thofe whvich are thus pointed out, that might be miftaken for 

 them. In fuch cafes an additional precaution has been ufed by 

 mentioning fome circumftance either of magnitude orfituation, 

 to diiKnguifh the intended fi:ar from the refl. After all, if any 

 obferver fhould be ftill at a lofs to find thefe flars without having 

 their right afcenfion and declination, he may furnifh himfelf 

 with them by means of F.lamsteed's Atlas Cceleflis ; for my 

 defcription will be fufficiently exa6t for him to make a point in 

 the maps to denote the flar's place; then, by means of the gra- 

 duated margin, he will have its A and declination to the time 

 of the Atlas, which he may reduce to any other period by the 

 ufual computations. 



Before I quit this fubje£l: I muft remark, that it will be found 

 en trial, that this method of pointing out a double ftar is not 



only
