86 is a remarkable group of nebul. It consists of eight, two of them 
pretty bright. Such groups are not uncommon, but in this instance there 
we have noticed. It was observed by Mr. Stoney. The nebule were 
not connected by any sig aa but there are cases where 
nebulous connection was distin ctly traced ; several minute nebulz, or 
takable nebulosity. The nebule of Andromeda and Orion have of 
course been observed. As to Andromeda, there seems to be little doubt 
that the companion is resolvable, and the nucleus of the great nebula 
has that granular appearance which indicates resolvability. It has how- 
ever, not been seen as yet under very favorable circumstances, and we 
have not commenced a sketch of it. e nucleus was examined on 
did not receive the drawing till the nebula was out of reach, otherwise 
of course more attention would have been directed to it. Subsequent 
to the receipt of the drawing, the nebula was seen by Mr. Stoney in my 
absence with the instrument of three feet vices ~~ at a distance 
from the meridian. The appearance was a much as in Mr. Bond’s 
rawing, except that the contrast between the prec ae portion as 
th 
o 
pay portion of the a, was much greater he question, how- 
ever most interest is, what do these streaks indicate? With the 
great pees a dark streaks have been observed in many of the neb- 
ulee—sometimes almost straight as in Andromeda ; for instance, H 887, 
1909 
> H 1041, H 1149, are cases in point, sie streaks being nearly 
— H 1357, to which Mr. Bond refers, is if possible a wi stronger 
se than it appears to be by Herschel’s drawing, as I fin sketch in 
1925, and others. Also H.1496,.H 464, H 2241, besides the well- 
known annular nebula and the little annular nebula, figure 48, sketched 
by Herschel, are some of the examples of nebule with comparatively 
dark centres; the darkness being apparently of the same quality as 
the dark streaks but of a different sha ape. 
With these facts therefore | think it not improbable that the dark lines 
noticed by Mr. Bond in the nebula of Andromeda, and which with ule
