5 6 Dr. Herschei/s Experiments on the Means 
might happen in the situation of any one of them. They were 
delineated as in Fig. i , ( Plate I. ) which is a mere eye-drauglit, 
to serve as an elucidation to a description given with it in the 
journal ; and the star marked k, as will be seen hereafter, was 
the new object. 
Sept. 25. The moon was too bright to see minute objects 
well, and my description the night before, for the same reason, 
had not been sufficiently particular ; nor did I expect, from 
the account received, that the star had retrograded so far in 
its orbit. 
Sept. 2 6. The weather being very hazy, no regular obser- 
vations could be made ; but as I noticed very particularly 
a star not seen before, it was marked / in Fig. 2, and proved 
afterwards to have been the lately discovered one, though still 
unknown this evening, for want of fixed instruments. 
Sept. 27. I was favoured with Dr. Maskelyne’s account of 
the place of the star, taken at the Royal Observatory, by which 
communication I soon found out the object I was looking for. 
Sept. 29. Being the first clear night, I began a regular series 
of observations ; and as the power of determining small angles, 
and distinctness in showing minute disks, whether spurious or 
real, of the instrument I used on this occasion, has been suffi- 
ciently investigated by the foregoing experiments, there could 
be no difficulty in the observation, with resources that were 
then so well understood, and have now been so fully ascer- 
tained. 
“ Mr. Harding’s new celestial body precedes the very 
“ small star in Fig. 3, between 29 and 33 Piscium, and is a 
“ little larger than that star ; it is marked A. f gh are taken 
“ from Fig. 1. I suppose g to be of about the 9th magnitude.
