DATES OF CONRAD.

at the distance of a thousand miles from, my present domi¬ 
cile; an arrangement that may possibly involve a few inac¬ 
curacies in my papers. But, as I hope to return to Phila¬ 
delphia 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 hereinafter described. 
“ Claiborne, Alabama, Nov. 1, 1833. 
“T. A. Conrad.” 
In the copy at the Academy of Natural Sciences Conrad 
has altered the above date with a pen to read Sept. 1st, as it 
was obviously incongruous that a letter written in Novem¬ 
ber should reach Philadelphia in time to be printed in Oc¬ 
tober of the same year, while it probably took a month for 
letters to go to Philadelphia from Claiborne, Ala., at that time. 
On Nov. 26, 1833, Dr. Morton presented to the library the 
fourth number of the work, as above described, which do¬ 
nation was probably made at the first meeting after the 
actual publication, not more than two weeks later than the 
w T ork was issued. (See Am. Journal of Conchology, vol. i, p. 
190.) Few copies of the original No. 4 are known to be in 
existence. There is one at the Academy and one at the 
Wagner Institute in Philadelphia. Messrs. Aldrich and 
Meyer possess copies, but there are probably not over six 
copies in existence. The tradition is that the entire edition, 
with the exception of a few copies, was purchased by friends 
of Dr. Lea and destroyed. As Conrad did not have access 
to Dr. Lea’s types at that time, his synonymy in the Ap¬ 
pendix to Morton’s “ Organic Remains ” (1834) is largely 
guess-work and contains many errors and some names, such 
as Cerithium sagenula, which have never been published at 
all. 
After his return from the South, Conrad set at work to re¬ 
deem the promise made in his name on the cover of No. 4, 
and issued in March, 1835, a paper covering the same ground
