The American list is entitled: ic Data concerning the determination 
of altitudes by the U. S. N. W. Boundary Commission in the years 
1857, 58, 59, and 60." 
This data is contained in two cahiers, of six double sheets each, 
designated Vol. I and Vol. II. The first one has been revised through- 
out; the second one is apparently revised in part only and is incom- 
plete. The data is in nine columns. The first gives the date u when 
occupied ;" the second, the name of station; third, barometer (desig- 
nated by number, 790, 1224, 1219, 1226); fourth, number; fifth, lati- 
tude; sixth, longitude; seventh, observer; eighth, altitude; ninth, 
remarks. We here print columns 2 and 9 (consolidated), 5,6, and 8. 
Elevations along the forty-ninth parallel from the Pacific Ocean to the Rocky Mountains, 
determined barometrically, in the years 1857-1860, by the British Northwestern Boundary
