view of my great reflector, with a power of 1 WE This cluffer 
appearing fo plainly with any good, commen telefcop: Ne. 
being fo near to the one which may be feen by the naked eye, 
denotes it to be probably the next in diftance to that within the 
quartile formed by y, 2, 4, 8; from the 67th nebula the ftratum 
of Cancer proceeds towards the head of Hy dta ; but I have not 
yet had time to trace it farther than the equator. 
Another ftratum, which perhaps approaches nearer to the 
folar fyftem than any of the reft, and whofe fituation is nearly 
at retangles to’the great fidereal ftratum in which the fon is 
placed, is that of Coma Berenices, as 1 fhall call it. I {uppofe 
the Coma itfelf to be one of the clufters init, and that, on ac- 
count of its nearnefs, it appears to be fo fcattered. It has 
many capital nebule very near it; and in all probability this 
ftratum runs on a very confiderable way. It may, perhaps, 
even make the circuit of the heavens, though very likely not 
in one or the great circles of the fphere: for, unlefs it thould 
chance to interfect the great fidereal ftratum of the milky way 
before-mentioned, in the very place in which the fun is fla- 

tioned, fuch an appearance could hardly be produced. . How- 
ever, if the ftratum of Coma Berenices fhould extend fo far as 
(by takimg in the affiftance of M. Mrssrer’s and M. MecHain’s 
excellent obfervations of fcattered nebulae, and fome detached 
former obfervations of my own) I apprehend it may, the di- 
redtion of it towards the north lies probably, with fome wind- 
ings, through the great Bear onwards to Cafliopeia ; thence 
through the girdle of Andromeda and the northern Fith, ‘pro- 
ceeding towards Cetus; while towards the fouth it pafles 
through the Virgin, probably on to the tail of Hydra andthe 
head of Centaurus. But, notwithftanding I have already fully 
afcertained the exiftence and direétion of this ftra, um for more
