 in which the third line is only suspected." Both must of

 have seen in the " finder." Can it have changed its cha- 

 racter since ? 



[iVo^e.— With four exceptions, Nos. 1843, 2076, 1565, 1801 (all be- 

 tween 7'^ & IP R.A.), the whole of the bright planetary nebulse between 

 80° and 150° N.P.D. have now been examined.
