192 COSMOS. 



Cluster of stars near c of the Southern Cross (No. 3435), 

 composed of many- coloured small stars from the 12th to 

 the 16th magnitude, distributed over an area of ^th of a 

 square degree ; a nebulous star, according to Lacaille, but so 

 completely resolved by Sir John Herschel that no nebulous 

 mass remained ; the central star deep red. ( Observations at 

 the Cape, pp. 17, 102, pi. 1, fig. 2.) 



Cluster of stars, 47 Toucani, Bode; No. 2322 of Sir John 

 Herschel' s catalogue, one of the most remarkable objects in the 

 southern heavens. I was myself deceived by it for several even- 

 ings, imagining it to be a comet, when, on my arrival at Peru, I 

 saw it in 12 south lat. rise high above the horizon. The visi- 

 bility of this cluster to the naked eye is increased by the 

 circumstance, that, although in the vicinity of the lesser 

 Magellanic cloud, it is situated in a part of the heavens con- 

 taining no stars, and is from 15' to 20' in diameter. It is of a 

 pale rose colour in the interior, concentrically enclosed by a 

 white margin composed of small stars (14th to 16th mag.) 

 of about the same magnitude, and presenting all the charac- 

 teristics of the globular form. 75 



A cluster of stars in Andromeda's girdle near v of this 

 constellation. The resolution of this celebrated nebula 

 into small stars, upwards of 1500 of which have been re- 

 cognized, appertains to the most remarkable discoveries 

 in the observing astronomy of the present day. The merit of 

 this discovery is due to Mr. Geo. Bond, assistant astronomer 76 

 at the Observatory of Cambridge, United States, (March, 



75 "A stupendous object a most magnificent globular 

 cluster," says Sir John Herschel, " completely insulated, upon 

 a ground of the sky perfectly Hack throughout the whole 

 breadth of the sweep." Observations at the Cape, pp. 18 and 

 51, PI. iii. fig. 1 ; Outlines, 895, p. 615.
