most unfortunately prevented our being able to observe any eclipses of 
Jupiter’s Satellites here, or the occultation of the star = Libra by the 
Moon, and I was sorry to find that my chronometers could not be depen= 
_ ded on to shew the difference of longitude in time: though they are of 
the best Kind, and hung in gimbals, no method of carriage that I had 
then adopted could prevent them feeling the effects of the short and con- 
Jinually repeated’ jerks they received from the’ uneven steps, which the 
man who carried them on his back was obliged to make. Nothing

‘Tu mean breadth of the Ganges at Gangotrt was (measured by the 
chain) 43 feet, depth 18 inches, and'nearly the same depth at the sides, 
as in the middle: the current very swift, and over large rounded stones. — 
This was on the 26th May, the stream was then in one channel, but the 
effect of the sun in melting the snow was at that season so powerful, 
that it was daily much augmented s. and on our return to Gangotri, on the 
2d June, the depth of the main. stream was 2 feet, and it was a few feet 
wider (but I did not then measure the width) ; several shallow side chan- 
nels had also been filled in the interval, and onthe whole, I estimate, that 
the volume of water was doubled. 
Tuoucn the frequency of the earthquakes made us very anxious to’ 
get out of our dangerous situation in the bed of the river, we reselved, as 
we had come so far, to leave no means untried to trace the stream as far
