My forces are not enfeebled, I find no decay in my strength; my 
provisions are not cut off, I find no abhorring in mine appetite; 
my counsels are not corrupted nor infatuated, I find no false 
apprehensions to work upon mine understanding; and yet they see 
that invisibly, and I feel that insensibly, the disease prevails.
