Bouvier's Law Dictionary, Revised 6th Ed (1856)
JUS GENTIUM. The law of nations. (q.v.) Although the Romans used these
words in the sense we attach to law of nations, yet among them the sense was
much more extended. Falck, Encyc. Jur. 102, n. 42.
2. Some modern writers have made a distinction between the laws of
nations which have for their object the conflict between. the laws of
different nations, which they call jus gentium privatum, or private
international law; and those laws of nations which regulate those matters
which nations, as such, have with each other, which is de nominated jus
gentium publicum, or public international law. Foelix, Droit Interm. Prive,
n. 14.
