I came across the following paragraph in Dickens' American Notes:
I have made no reference to my reception, nor have I suffered it to influence me in what I have written; for, in either case, I should have offered but a sorry acknowledgment, compared with that I bear within my breast, towards those partial readers of my former books, across the Water, who met me with an open hand, and not with one that closed upon an iron muzzle.
What does this mean? I would appreciate a paraphrase to help understand it.
