either plainly appeared to be nothing but ftars, or at leaft to: 
contain ftars, and to fhew every other indication of confifting 
of them entirely. 1 have examined them with a careful {eru- 
tiny of various powers and light, and generally in the meri- _ 
dian. I fhould mention, that five of the above, viz. the 16th, 
24, 375 52, 67, are called clufters of ftars containing nebulo- 
fity; but my inftrument refolving alfo that portion of them 
which is called nebulous into ftars of a much {maller fize, I 
have placed them into the above number. To thefe may be 
added the +ft, 3d, 27,33, 57, 79, 81, 82, 191, which in my 
7, 10, and 20-feet reflectors fhewed a mottled kind of nebulo- 
fity, which I fhall call refolvable; fo that I expect my prefent 
telefcope will, perhaps, render the ftars vifible of which |

inftrument with regard to nebule. 
My prefent purituits, as I obferved chai requiring this 
telefcope to act as a fixed inftrument, I found it not convenient 
to apply it to any other of the nebula in the Connodfance des —

to take any particular pains to look for them, it being utterly: 
impoflible that any one of them fhould efcape my obfervation _

I have already had.an opportunity of examining, fhew plainly that
