Note 036 Exercitus ab exercitando, Varro de Lingua Latina, 1. iv. Cicero in Tusculan. 1. ii. 37. There is room for a very interesting work, which should lay open the connection between the languages and manners of nations.

N.B. Such a work now exists. "A Study Of Our Decline" reveals the relationship between the culture of a community and its language.

Note to Chapter 1 of DECLINE & FALL by Gibbon
