Tuis then may be taken as the probable height of the Chir station 
above Belville. To which adding* 1013 feet for the height of the latter, 
above the sea as determined from barometrical calculation, we get finally 
for the height of the Chir station above the sea 11,689 feet. From this 
the following mean values may be fixed by applying the several mean dif- 
ferences of level before found.

* Vour first calculations gave but 353 feet for this-height, ‘but the .observations were much Jess 
complete than those subsequently made as described below. It has therefore been necessary to 
cancel the first list of results, and to substitute a new one in which the difference of .160 feet has 
been added to the elevations fermerly inserted, and a-number of additional observations have been 
appended.
