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 Nicollet's data, I see one rather 

 important error, and that is in taking the low water elevation of the Mis- 

 sissippi at New Orleans at 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 5-10ths of a foot, and 

 consequently a slope of only about 5-1000lhs of a foot thence to the 

 mouth ; and not 9-10ths, as in Dr. Engelmann'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.
