284 Mr Durilop's Catahgue of Nebulw and 



which the Brisbane Observatory has been the means of putting 

 the world in possession of, respecting that important and hi- 

 therto but little known portion of the heavens. 



Mr Dunlop then proceeds to give his observations in detail 

 on no fewer than 629 different nebulae ; but as it is impossible 

 in a work like this to reprint so large a catalogue, we have se- 

 lected the most curious and interesting nebulae, and those 

 which are most likely to attract the notice of the philosopher 

 in his speculations on the construction of the heavens.

This is a beautiful large round nebula, about 8' diameter, 

 very gradually condensed to the centre. This beautiful globe 

 of light is easily resolvable into stars of a dusky colour. The 

 compression to the centre is very great, and the stars are con- 

 siderably scattered south preceding and north following. —

A beautiful bright round nebula, about 4' diameter, exceed- 

 ingly condensed. This is a good representation of the 2d of 

 the Connaissance des Tems in figure, colour, and distance ; it 

 is but a very little easier resolved, rather a brighter white, and 

 perhaps more compact and globular. This is a beautiful^ 

 globe of white light ; resolvable : the stars are very little scat 

 tered.

A star of the 6th magnitude, with a beautiful well-definec 

 milky ray proceeding from it south following ; the ray is C( 

 nical, and the star appears in the point of the cone, and th< 

 broad or south following extremity is circular, or rounded offJi 

 The ray is about 7' in length and nearly 2' in breadth at th< 

 broadest part, near the southern extremity. With the sweep-j 

 ing power this appears like a star with a very faint milky raj 

 south following, the ray gradually spreading in breadth froi 

 the star, and rounded off at the broader end. But with 

 higher power it is not a star with a ray, but a very faint nebu- 

 la, and the star is not involved or connected with it : I shouh 

 call it a very faint nebula of a long oval shape, the smaller end'
