the direétion of its equatorial movement, now formed: swith 
it an evident angle, and at the fame time had proceeded 
fouthwards the like diftance. Befides the fatell ite three 
telefeopic fixed {tars were diftinguithable in @, 8, y. (f ig. 2.) 
_About ten o’clock we continued our obferyations with the 
twenty-feven feet reflector, and M. Harding, befides the fall 
ftars which had now moved.a little thu, their place, ob- 
ferved two moye,in dand ¢ (fig. 3.) In the ftrong light of 
this telefcope the fecond larger fatellite, now moved to ¢, which 
from its difance, colour, and degree of light, we perceived 
toebe the fame obferyed on the 19th and the goth, diftine 
guithed itfelf clearly from the other {mall ftars, and even 
from the firft fatellite, though its light was very weak. At 
the fame time we obferved the direction of its equatorial. 
motion towards ¢, fo that both the fatellites, according to 
the proportion of the periods of their revolution, feemed to 
have moved fouthwards.. By this circumftance, and as 
it was impoflible that with a reflector having fo much light 
we fhould not, in ferene weather, fee both the fatellites, we 
were more confirmed in our opinion. 
As the weather was unfavourable I could not repeat my 
obferyations till the 26th of February, at42 minutes paft 10, 
when, with the thirteen feet reflector anda magnifier of 
288, 1 diftinguifhed two faint luminous points in quite 
-anather pofition, viz. one in g (fig. 1.), which I took to be 
the fecond or larger fatellite, and another in 4, which I con- 
fidered as the firft. Both thefe points correfponded with 
-Herfchel’s periods; fo that we could form no other conclue 
_fion than that, with this excellent reflector, we had feen
