(b ) There was a miftake of twelve hours in fetting down this obfervation at 
Greenwich, by the clock keeping fidereal time, which made an error of i' 49" 
in the redu&ion to apparent time. The correct time of imrnerlion is i6 h 59' 3 1", 
which happens to agree exactly with Mr. waecentin’s calculation, and the 
difference of longitude of Stockholm and Greenwich by this obfervation is 
i h 12' 14" inftead of i h 10' 25 fet down above; and the mean difference frem 
all the f«ven correfponding immerfions is i h 12' 30'’'. See the errata- printed 
with my Obfervations. n. m.
