these ancient wars with the Tallagees or Allegewy, may be thought to refer to this ancient people, who had, if this conjecture be correct, extended their dominion to the middle and northern latitudes of the present area of the United States, prior to the appearance of the Algonquin and Iroquies races. Mr. Irving has suggested the name of Apallachia, or Allegania, derived from the stock, for this division of the continent. LANGUAGE. LECTURES ON THE GRAMMATICAL STRUCTURE OF THE INDIAN LANGUAGE. The course of lectures, of which the following are part, were delivered before the St. Mary's committee of the Algic Society. Two of them only have been published. They are here continued from the article "Indian Languages," at page 202 of the "Narrative of the Discovery of the actual Source of the Mississippi, in Itasca Lake," published by the Harpers, in 1834. The family of languages selected as the topic of inquiry, is the Algonquin. All the examples employed are drawn from that particular type of it which is called Chippewa, in our transactions with them, but which they uniformly pronounce themselves, Od-jib-wa. These terms are employed as perfect synonyms. The phrase "Odjibwa-Algonquin," wherever it occurs, is intended to link, in the mind of the inquirer, the species and the genus (if we may borrow a term from natural history) of the language, but is not fraught with, or intended to convey, any additional idea. The three terms relate to one and the same people. LECTURE III. Observations on the Adjective--Its distinction into two classes denoted by the presence or absence of vitality--Examples of the animates and inanimates--Mode of their conversion into substantives--How pronouns are applied to these derivatives, and the manner of forming compound terms from adjective bases, to describe the various natural phenomena--The application of these principles in common conversation, and in the description of natural and artificial objects--Adjectives always preserve the distinction of number--Numerals--Arithmetical capacity of the language--The unit exists in duplicate. 1. It has been remarked that the distinction of words into animates and inanimates, is a principle intimately interwoven throughout the structure of the language. It is, in fact, so deeply imprinted upon its grammatical forms, and is so perpetually recurring, that it may be looked upon, not only as forming a striking peculiarity of the language, but as constituting the fundamental principle of its structure, from which all other rules have derived their limits, and to which they have been made to conform. No class of words appears to have escaped its impress. Whatever concords other laws impose, they all agree, and are made subservient in the establishment of this.
