_ Tuts was a very distinct observation, and I followed the satellite deep 
into the shadow, it gradually losing light for 76 seconds before its total 
disappearance—yet it gives a longitude almost’a minute East: of the 
first satellite, the preceeding night; which leads me to suspect, that though 
I know, the seconds were rightly counted'and noted, that the minute may 
have beet’ inadvertently noted 13" instead of 12". As. there, is this 
uncertainty, I will reject the observation: nevertheless it may be interesting 
to know, supposing. that. the case,. what the longitude could come out:

4 Emersions of the first satellite, which I observed at Mr, GrinpDauu’s 
house near Seharanpir; Mr. Goutpincuam finds 5" 10" 24° for the 
longitude of Seharanpir.—A snowy peak called Sré Canta is visible 
both from Reital and Seharanpir, its ‘position is determined by means 
of'a series of triangles instituted by me for the purpose of taking the dis-
