Although my notes of 1853-1854 of the exploration of Lieut. A. W. Whipple have been made use of to a certain extent for the geographical distribution of the basalt, triassic, and carboniferous rocks, I requested Lieutenant Wheeler to withdraw my name from the list of geological assistants, on the ground of difference of opinion in regard to the geological age of several groups of rocks.-J.
