rande is rut her crusty, and in bad grace, and no wonder, as he reviewed 
the ground in 1859. Then Hall was his pala?ontological dictator, as lie 
has been through the whole survey, but he could not resist the over- 
whelming truths produced by Billings. 
I am. my dear sir. very truly your friend.

Mv Dear Professor : 
I am highly gratified and obliged to you for your active assistance to 
dispel errors and do justice to science and to a most worthy man. * * * 
Mr. Billings speaks of you in the highest terms both personally aud as a 
man of science. We hear nothing from Emmons ; he will feel grateful 
when he learns that you and Billings have devoted your talents to sus- 
tain him. I hope very soon to hear from him and will let you know at 
•once. 
I do not understand French well enough to write to Barrande, and I 
beg you to offer him my highest regards and thanks for his valuable as- 
sistance in exposing the errors of our palaeontologist of the state of New 
York and doing justice to Emmons and his friends. 
I am very truly your friend, 
E. Jewett.

My Dear Professor: 
Many thanks for your most excellent paper on '"the Taconic and 
Lower Silurian rocks of Vermont and Canada,' 1 November, 1861, Bos- 
ton; nothing for years has given me more pleasure, for it fixes unalter- 
ably the long disputed facts. * * * Dr. Emmons will owe you and 
Billings great gratitude for your noble and generous assistance, and as I 
used all my efforts in his behalf * * * I offer you my most cordial 
and sincere thanks. 
I do so want to communicate the news to our honest and good friend 
Emmons ! but he is not to be corresponded with, and sealed up by the 
Rebellion. Whence comes back had we not better get up an ovation 
for him to let mankind know his worth and merit? He is one of the 
most modest and unassuming men I ever saw. * * * Let me again 
thank you for the very efficient and lucid labor in the cause of science 
and truth. I am very truly your obliged and sincere friend.

In July. 1861, I received from Barrande ;i large bundle, con- 
taining thirty copies of his "Documents anciens et nouveaux sur la 
faune primordiale et le systeme Taconique en Amerique," twelveoi 
which were addressed to Dr. Emmons. It was impossible to com- 
municate with him and I sent the bundle to colonel Jewett. who
