260 Mr, Herschel on the 
diameter, cannot be otherwife than of a wonderful magnitude, 
and may well outvie oux milky-way in grandeur. 
The firft I fhall mention is a milky Ray of more than a de- 
gree in length. It takes k (Fl. 52.) Cygni into its extent, to 
the north of which it is crookedly bent fo as to be convex 
towards the following fide ; and the light of it is pretty intenfe. 
To the fouth of k it is more diffufed, lefs bright, and lofes 
itfelf with feme extenftoii in two branches, I believe ; but for 
want of light I could not determine this circumftance. The 
northern half is near two minutes broad, but the fouthern is 
not fufficiently defined to afcertain its breadth. 
The next is an extremely faint milky Ray, above f degree 
long, and 8 or io / broad; extended from north preceding to 
fouth following. It makes an angle of about 30 or 40 degrees- 
with the meridian, and contains three or four places that are 
brighter than the reft. The ftars of the Galaxy are fcattered 
over it in the fame manner as over the reft of the heavens. It 
follows e Cygni 1 1,5 minutes in time, and is 2 0 19' more fouth. 
The third is a branching Nebu lofty of about a degree and a 
half in right afcenfon, and about 4s 7 extent in polar diftance. 
The following part of it is divided into feveral ftreams and 
windings, which, after feparating, meet each other again 
towards the fouth. It precedes Cygni i6 ; in time, and is 
i° 1 6' more north. I fuppofe this to be joined to the preceding 
one; but having obferved them in different fweeps, there was 
no opportunity of tracing their connection. 
The fourth is a faint, extended milky Ray of about iy' in 
length, and i2 y in breadth. It is brighteft and broadeft in the 
middle, and the ends lofe themfelves. It has a fmall, round, 
very faint nebula juft north of it ; and alfo, in another place, 
a fpot, brighter than the reft, almoft detached enough to form 
a different
