I believe from my own personal experience
I believe I can speak for all
I believe I shall make it clear to you
I believe I voice the sentiment
I believe it to be the simple truth
I believe most profoundly
I believe that I am within the mark
I believe that in this instance
I bid you a most cordial and hearty welcome
I bow with you in reverent commemoration
I call on you to answer
I call to mind how

I can not say how glad I am
I can not say with confidence
I can not stop to give in detail
I can not sufficiently thank you
I can not take back my word
I can not take it for granted

I can only hope for indulgence
I can readily understand
I can scarcely concede anything more important
I can scarcely find fitting words
I can strongly recommend
I can understand, moreover
I can with propriety speak here
I certainly have not so good an opinion
I challenge any man
I cheerfully own
I cheerfully submit myself
I claim a share also for
I class them altogether under the head
I close with the words
I close with this sentiment
I come at length to
I come next to the question of
