Professor Hall in his letter to the select committee of the Legisla- 
ture of 1849, (See report of the committee page 68,) says, that the 
geological sections were originally intended for the first volume ; but 
in its completion it was found impossible to include them, and they 
are therefore deferred to the last volume.
