The termination of the struggles between the old and new burgesses,
the various and comparatively successful endeavours to relieve the
middle class, and the germs--already making their appearance amidst
the newly acquired civic equality--of the formation of a new
aristocratic and a new democratic party, have thus been passed
in review.
It remains that we describe the shape which the new
government assumed amidst these changes, and the positions in which
after the political abolition of the nobility the three elements of
the republican commonwealth--the burgesses, the magistrates, and
the senate--stood towards each other.
