The last number of this work was exclusively devoted 

 to the fossil shells of the CALCAIRE GROSSIER, or middle 

 tertiary deposits' of Alabama, and I now continue this in L 

 teresting part of my subject. I have to regret the ne- 

 cessity of publishing at the distance of a thousand miles 

 from my present domicile ; an arrangement that may pos- 

 sibly involve a few inaccuracies in my papers. But, as I 

 hope to return to Philadelphia in the spring of next year, 

 I shall then employ my time assiduously in arranging the 

 numbers of this work in a single volume, which will be 

 illustrated . by upwards of thirty plates, and embrace an 

 accurate view of the strata containing the fossils herein- 

 after described.
