"When in Maryland I read an elaborate attempt to refute the 

 Copernican system of astronomy, and was quite surprised after 

 waiting some days or weeks to find that no one ventured to point 

 out the writer's fallacies. Fearing that sound knowledge was in danger, 

 I at length ventured in a reply which in due time appeared over my name 



in 'The Intelligencer.' It provoked two pleasing attentions — 



a book from Col. C. J. Albert, of the topographical engineers, and a 

 letter and a pamphlet from Prof. J. Lawrence Smith." Autobiographical
