Observe, if you please, that
Occasionally it is whispered that
Of course, it will be said that
Of no less import is
Of the final issue I have no doubt. 
On the contrary
On the one hand
On the other hand
On the other hand, you will see
On the whole, then, I observe
One word more and I have done. 
Once more, how else could
One fact is clear
Only a few days ago
Our position is that
Our position is unquestionable. 
Over and over again it has been shown that

Perhaps, sir, I am mistaken in
Perhaps the reason of this may be
Permit me to add another circumstance
Permit me to remind you
Please remember that if

Readily we admit that

Since you have suffered me to
So far is clear, but
So it came naturally about
So much for
Some men think, indeed, that
Some persons have exprest surprize that
Something of extravagance there may be in
Strange as it may seem
Strictly speaking, it is not
Such an avowal is not
Such is not my theory. 
Such is steadfastly my opinion that

Supposing, for instance,
Surely I do not misinterpret the spirit

Take the instance of
That is quite obvious. 
That we might have done. 
The audacity of the statement is
The charge is false. 
The conclusion is irresistible. 
The contempt that is cast

There is much force in
There is no danger of our overrating the
There is no evidence that
There is no good reason why
There is no mistaking the fact
There is no other intelligible answer
There is no parallel to
There is no sufficient reason for
There is none other. 
There is not a shadow of
There is one other point connected with
There is one other point to which
There is something suggestive in
There was a time when none denied it.
