 discovering truth ; they were made acquainted with the 

 great principle which connects together the most distant 

 regions of space, as well as the most remote periods of 

 duration ; and which was to lead to future discoveries, 

 far beyond what the wisest or most sanguine could an- 

 ticipate.
