^4b Ohervattofis on the new celestial Body 



made, were carefully examined with several magnifyiilg 

 powers, that in case any one of them should hereaiicr ap- 

 pear to have been the lately discovered object, I might not 

 lose the opportunity of an early acquaintance with its con- 

 .dition. An observation of the star marked A, in parti- 

 cular, was made with a very distinct magnifying power of 

 46o, and says, that it had nothing in its appearance that 

 differed from what we see in other stars of the same size ; 

 indeed Dr. Olbers, by mentioning in the communication 

 which I received, that with such magnifying powers as he 

 could use it was not not to be distinguished from a fixed 

 star*, had already prepared me to expect the newly dis- 

 covered heavenly body to be a valuable addition to our in- 

 creasing catalogue of asteroids. 



The 25th of April 1 looked over my delineations of the 

 preceding evening, and found no material difference in the 

 situation of the stars I had marked for examination ; and in 

 addition to them new asterisms were prepared, but on ac- 

 count of the retarded motion of the new star, which was 

 drawing towards a period of its retrogradation, the small 

 change of its situation was not sufficiently marked to be 

 readily perceived the next day when these asterisms were 

 again examined, which it is well known can only be done 

 with night-glasses of a very low magnifying power. 



A long interruption of bad weather would not permit any 

 reofular examination of the situation of small stars : and it 

 was only when I had obtained a more precise information 

 from the astronomer royal, v^ho, by means of fixed in- 

 struments, was already in possession of the place and rate 

 of motion of the new star, that 1 could direct my telescope 

 with greater accuracy by an applcaition of higher magni- 

 fying powers. My observations on the nature of this se- 

 cond new star discovered by Dr. Olbers arc as follow. 



April 24. This day, as we have already seen, the new 

 celestial object was examined with a high power; and since 



* Der neue planet zeigt sich als ein stern zwischen der 5ten und Gten 

 grcisse und Ut im fernrohr, wenigsten mit den vergrisserungen die ich^au- 

 wsnden kann, von cinen fixstern nicht zu unterschelden.
