Bouvier's Law Dictionary, Revised 6th Ed (1856):

BUREAUCRACY. The abuse of official influence in the affairs of government;
corruption. This word has lately been adopted to signify that those persons
who are employed in bureaus abuse their authority by intrigue to promote
their own benefit, or that of friends, rather than the public good. The word
is derived from the French.
