 tenths of the nebulous Contents of thc heavens consist of ne- 

 bulae of spherical or elliptical forms, presenting every variely 

 of elongation and central condensation. Of these a great number 

 have been resolved into distanl stars (by the Rcfleclor of the 

 Earl of Rosse), and a vast multilude more have been found to 

 present that motlled appearance, which renders it almost a 

 matter of certainty that an increase of optical power would show 

 them to be similarly composed. A not unnatural or unfair in- 

 duclion would therefore seem to be, that those which resist 

 such' resolulion, do so only in consequence of thc smallness 

 and closeness of thc stars of which they consist: that, in short, 

 they are only optically and not physically nebulous. — Allhough 

 nebulac do exist which even in this powerful telescope (of Lord 

 Bosse) appear as nebulae, without any sign of resolulion, it may
