1836 is now a sin 
equatorial. The motion is evidently slow, and it is remarkable 
that Herschel says of this star, ‘‘Cleanly divided with power 
and the black division well seen, well separated with power 800” ; 
and of + Lupi he says, “‘I do not think measures of this star will 
be got with this instrument.” ‘“ Excessively difficult. It is closer 
than y Lupi, for the discs are smaller, and yet are not so much 
divided.” Now I found x Lupi quite an easy object, and the mean 
of my measures make the distance 0°73’, while Herschel made it 
0°67", so that there has been no great change in this star. But 
y Lupi, which h. found so easy, I have examined a great many 
times and always failed to divide it even with the greatest powers 
on the large refractor 
Another star of the same character it would seem is h, 4854. 
h. classes this as “very difficult to be verified.” On June 4, 
1872, at the end of myevening’s work, I looked at itand divided it 
easily with power 230 ; I only took one measure, making the angle 
46° 25’, and the distance 1-75”, being satisfied that in this case, as 
in many others, that what was very difficult in Herschel’s reflector 
be s '

leaks explanation is that the stars have changed since he
