It remains for us to consider
It remains to
It remains to be shown that
It reminds me of an anecdote
It seems a truism to say
It seems now to be generally admitted
It should also be remembered that
It should be remembered
It so happens that
It was my good fortune
It was not so
It was under these circumstances
It were foolish to talk of
It were rash to say
It will be easy to cite
It will be found, in the second place,
It will be observed also that
It will be well to recall
It will not surely be objected
It would be misleading to say
It would be no less impracticable to
It would be vain to seek
It would do no good to repeat
It would seem that

Largely, I have no doubt, it is due
Let it be repeated
Let it be for an instant supposed
Let me add that
Let me ask who there is among us
Let me explain myself by saying
Let me illustrate
Let me instance in one thing only

Neither is it true that
Nevertheless, we must admit

No man who listens to me underrates
No matter what
No, no. 
No objection can be brought against the
No one realizes this more
No one will, with justice, say
No one will question
No one would take the pains to challenge the
No wonder, then, that
Nobody really doubts that
Nor am I, believe me, so arrogant as
Nor can we imagine that
Nor is this surprizing
Nor, lastly, does this
Not a few persons demand
Not many words are required to show
Not quite so. 
Not so here. 
Nothing is more certain than
Nothing less. 
Now, after what I have said,
Now apply this to
Now do you observe what follows from
Now for one moment let us
Now I have done. 
Now, I proceed to examine
Now I want to ask whether
Now it is evident
Now let us observe what
Now, mark it. 
Now, on the other hand, let me
