dated West Point, Dec. 19, 1860 : 
Nathaniel Holmes, A.M., 
Cor. Sec. Acad. Science St. Louis. 
Dear Sir : In looking carefully over the table given by Dr. Engelmann, 
p. 666, Vol. I., No. 4, calculated from Nicollel^s data, I see one rather 
important error, and that is in taking the low water elevation of the Mis- 
sissippi at New Orleans ai 10 feet above the Gulf. This is the level of the 
pavement in front of the Cathedral. A note in Mr. Nicollet’s table, taken 
from Albert Stein, gives this low water elevation 5 lOths of a foot, and 
consequently a slope of only about 5-lOOOIhs of a foot thence to the 
mouth ; and not 9-lOlhs, as in Dr. Engelrnann’s table. This very slight 
fall in so long a distance could scarcely be credited were it not a well 
established fact. Respectfully, your ob’t serv’t, 
G. K. Warren, Lieut. Top. Eng’rs.
