The inhabitants within the walls were divided into four "regions" or districts--the Palatine, the Colline, the Esquiline, and the Suburran. The subjected districts outside, which were inhabited by plebeians, were divided into twenty-six other regions, thus forming thirty tribes containing both plebeians and patricians. The census gave Servius a list of all the citizens and their property, and upon the basis of this information he separated the entire population into six classes, comprising one hundred and ninety-three subdivisions or "centuries," thus introducing a new principle, and placing wealth at the bottom of social distinctions, instead of birth. This naturally pleased the plebeians, but was not approved by the citizens of high pedigree, who thus lost some of their prestige. The newly formed centuries together constituted the _Comitia Centuriata_ (gathering of the centuries), or National Assembly, which met for business on the Campus Martius, somewhat after the manner of a New England "Town Meeting." In these conclaves they elected certain magistrates, gave sanction to legislative acts, and decided upon war or peace. This Comitia formed the highest court of appeal known to Roman law. Besides this general assembly of the entire Populus Romanus, Servius established a _Comitia_ in each tribe, authorized to exercise jurisdiction in local affairs. The first of the six general classes thus established comprised the Horsemen, _Equites_, Knights, or Cavalry, consisting of six patrician centuries of Equites established by Romulus, and twelve new ones formed from the principal plebeian families. Next in rank to them were eighty centuries composed of persons owning property (not deducting debts) to the amount of one hundred thousand ases (_æs_, copper, brass, bronze), and two centuries of persons not possessed of wealth, but simply _Fabrûm_, or workmen who manufactured things out of hard material, so important to the state were such considered at the time. One would not think it very difficult to get admission to this high class, when it is remembered that an _as_ (originally a pound of copper in weight) [Footnote: The English word _ace_ gets its meaning, "one," from the fact that in Latin as signified the unit either of weight or measure. Two and a half ases were equal to a sestertius, and ten ases (or four sesterces) equalled one denarius, worth about sixteen cents.] was worth but about a cent and a half, and that a hundred thousand such coins would amount to only about fifteen hundred dollars; though, of course, we should have to make allowance for the price of commodities if we wished to arrive at the exact value in the money of our time. The second, third, and fourth centuries were arranged on a descending grade of property qualification, and the fifth comprised those persons whose property was not worth less than twelve thousand five hundred ases, or about two hundred dollars. The sixth class included all whose
