It is difficult to surmise
It is doubtful whether
It is easy enough to add
It is easy to instance cases
It is easy to understand
It is eminently proper
It is every man's duty to think
It is evident that the answer to this
It is evidently supposed by many people
It is exceedingly gratifying to hear
It is exceedingly unfortunate
It is fair that you should hear
It is fair to suppose
It is far from me to desire
It is fatal to suppose
It is fitting
It is for me to relate
It is for others to illustrate
It is for this reason
It is for us to ask
It is greatly assumed
It is gratifying to have the honor
It is hardly for me
It is hardly necessary to pass judgment
It is idle to think of
It is immaterial whether
It is impossible to avoid saying
It is in every way appropriate
It is in the highest degree worthy
It is in this characteristic
It is in vain
It is in your power to give
It is indeed a strange doctrine
It is indeed not a little remarkable
It is indeed true
It is indeed very clear
It is indispensable to have
It is interesting and suggestive
It is interesting to know
It is just so far true
It is likewise necessary
It is made evident
It is manifest
It is manifestly absurd to say
It is merely common sense to say
It is more than probable
It is my agreeable duty
It is my belief
It is my earnest wish
It is my grateful duty to address you
