It is to be regretted that we are unable to give satisfactory information as to the proportional numbers.

We may estimate the number of Roman burgesses capable of bearing arms in the later regal period as about 20,000.

(I.VI.Time And Occasion of the Reform) Now from the fall of Alba to the conquest of Veii the immediate territory of Rome received no material extension; in perfect accordance with which we find that from the first institution of the twenty-one tribes about 259, (II.II.

Coriolanus) which involved no, or at any rate no considerable, extension of the Roman bounds, no new tribes were instituted till 367.

However abundant allowance we make for increase by the excess of births over deaths, by immigration, and by manumissions, it is absolutely impossible to reconcile with the narrow limits of a territory of hardly 650 square miles the traditional numbers of the census, according to which the number of Roman burgesses capable of bearing arms in the second half of the third century varied between 104,000 and 150,000, and in 362, regarding which a special statement is extant, amounted to 152,573.
