34 Is a changeable star. Its period perhaps is about 18 years. 
See Phil. Trans. Vol. LXXVI. page 201. 
38. In Flamsteed's observations, page 73, a star was taken 
without RA, marked “ quse prascedit «.” The time of this 
observation however is sufficiently determined by the 37 be- 
fore it, and 45 and 4b just after ; but there is no star visible 
in the space pointed out that can possibly be taken for 38. 
“ Sept. 22, 1783, 38 lost. There is not a star of the 7, 8, 9, or 
10th magnitude near the place.” It therefore does not exist, 
or rather is lost. 
41 Is less than 21, and not much larger than 32, which is 
contrary to the catalogue. “ It is less than 4m.” In Flam- 
steed's observations it is marked 4m, but 21 and 32 are without 
magnitudes. • 
48. “ Sept. 3, 1784; I could not see this star, but instead 
of it found in the neighbourhood 2 stars of the 7th magnitude 
within 3 or 6' of each other." “ Nov. 13, 1795. If one of 
the stars be 48, its magnitude is over-rated, and must be about 
7.8m. That of the two which is nearest to 49 is the largest.” 
39 Is less than 33, 36 and 63, contrary to the catalogue. It 
is also contrary to the magnitudes given in the observations : 
63 is without magnitude. 
66 Is larger than 78, contrary to the catalogue. See 78. 
“ Sept. 13, 1784; 20-feet reflector 66 (v) 4m> Fl. 3m. It is 
larger than 34(A), contrary to the catalogue.” Neither 66 
nor 34 have any magnitude in Flamsteed's observations. 
71 Is equal to 80, contrary to the catalogue. Neither of 
them has any magnitude given with them in the observations.
