a different nebula, but probably belonging to the great one. 

 The Ray precedes a Trlanguli 18', 8 in time, and is 55' more 

 north. Another obfervation of the fame, in a finer evening, 

 mentions its extending much farther towards the fouth, and' 

 that the breadth of it probably is not lefs than half a degree ; . 

 but being (liaded away by imperceptible gradations, it is ditii-- 

 cult exactly to affign its limits. 



The fifth is a Streak of light about 27'' long,, and in the 

 brlghteft part 3 or 4^ broad. The extent is nearly in the meri- 

 dian, or a little from fouth preceding to north following. It 

 follows jS Ceti 5^,9 in time, and is 2° 43'' more fouth. The 

 fituation is {q low, that it would probably appear of a much 

 greater extent in a higher altitude. 



The lixth is an extenfive milky Nebulofity divided into two 

 parts; the moil north being the ftrongeft. Its extent exceeds 

 15'; the fouthern part is followed by a parcel of ftars which 

 1 fuppofe to be the 8th of the Cunnoijfance des Temps,, 



The feventh is a wonderful, extenlive Nebulofity of the milky 

 kind. There are feveral ftars vifible in it, but they can have 

 no connection with that nebulofity, and are, doubtlefs, belong- 

 ing to our own fyflem fcattered before it. It is the 17th of 

 the Connoijfance des Temps, 



In the lift of thefe muft alfo be reckoned the beautiful Ne- 

 bula of Orion. Its extent is much above one degree ; the 

 eaftern branch paffes between two very fmall ftars, and runs on 

 till it meets a very bright one. Clofe to the four fmall itars, 

 which can have no connection with the nebula, is a total black- - 

 nefs ; and within the open part, towards the north-eaftj is a 

 diftind, fmall, faint nebula, of an extended (hape, at a diftance 

 from the border of the great one, to which it runs in a. parallel 

 4 ^ direction,,
