Post-soriptum. — Although thirty years have elapsed since Dr. 
Emmons left Albany for North Carolina, never to return alive,

discoveries and views has kept the character of disingenuousness, 
and covert persecution to his adherents shown from the beginning, 
forty-five years ago. 
Finding it impossible to deny any longer the priority of his dis-

ents to Emmons' views has increased ten-fold from what they 
were in 1863, notwithstanding the death of Emmons. Barrande, 
Billings, and Jewett, But the same spirit of lowering the 
national record of American geology, and of throwing dust into 
the eyes of those who cannot see and judge for themselves in the

The number of original and well trained observers is still too 
limited on this continent, and the ground to cover is too great. 
So it is still relatively an easy task — although not so easy as it 
was in 184o — to make such combinations of unscrupulous geolo-
