Be these things as they may
Be your interests what they may be
Bear with me for a few moments
Bearing on this point
Before attempting to answer this question
Before going further
Before I close I will particularly remark
Before I come to the special matter
Before I proceed to compare
Being fully of the opinion
Being persuaded then
Believing, as I do
Beyond all question we
Bidden by your invitation to a discussion
Broadly speaking
But, above all things, let us
But after all, I think no one can say
But again, when we carefully consider
But am I wrong in saying
But apart from the fact
But besides these special facts
But can this question
But depend upon it
But despite all this
But do not let us depend
But do you imagine
But doubts here arise
But even admitting these possibilities
But everyone who deserves
But first of all, remark, I beg you
But, further, I shall now demonstrate
But, gentlemen, I must be done
But grave problems confront us
But here I am discussing
But here let me say
But how can we pass over
But how shall I describe my emotions
But however that may be
But I am bound to say
But I am certain from my own experience
But I am very sorry to say
But I am willing enough to admit
But I can at least say
But I can not conceive
But I can promise
But I cherish the hope
But I confess that I should be glad
But I digress
But I do not propose all these things
But I do say this
