a Aneroid No. 7992 not computed. 
Note. —The barometric observations for the remainder of the route are of the aneroids, and have no value in determina¬ 
tions of altitudes. The temperature observations are continued, in a different arrangement, as far as Fort Colville, with some 
references to the readings of the aneroid barometer.
