nouns substantive and adjective, and the adverbs.

If a part of a verb is to be dictated, I first make the sign for the personal pronoun, which carries along with it that for number; then the radical sign; and, according to what is requisite, the sign for tense and mood. When active, there is no need to notice the voice; but when passive, the sign must necessarily be made, as before explained.

If I want to dictate friendship, I make the radical sign, accompanied by the sign for substantive, which will be enough to make it understood that such is the noun substantive I require.

If love is the noun I want, I make the same signs as for friendship, only giving a greater degree of vivacity to my action on the mouth and on the heart, because love is more ardent than friendship, even in a religious sense, the sense in which we always employ it.

The word beloved, is an adjective, agreeing both to masculine and feminine. The sign for adjective subjoined to the radical sign will suffice.

Is amiable the word? I make the radical sign, then the sign for an adjective, but of one terminating in able formed from a verb: to this I must subjoin the sign for possible, or for necessary as before laid down.

By substantifying this adjective, as before observed, we have amiableness.

The term friend, is correlative; it implies two persons having a friendship for each other. Supposing I am one of the two myself, I show myself and make the radical sign; then with the end of my finger either point out the person who is my friend, or indicate his name. Having made the radical sign a second time, I turn the end of my finger towards myself, to show that the friendship of that person is directed to me as mine is directed to him.

Is amiably to be expressed? I make the

radical sign, and the sign for adverb (possible or necessary, according to the sensé of the phrase); I add a sign announcing that there is no contestation, after that I put my hand upon my right side, to make it understood that it is an adjective adverbified as we have mentioned in a preceding page.

Have I to dictate amicable? I make the radical sign, and with a good-humoured smile I give a child a few taps on the ear in a friendly manner. In subjoining to these signs the sign for adverb, the word amicably will be formed.

An amateur, is a person conversant with painting, sculpture, &c. and fond of seeing productions in those arts. I show the objects of fondness, and make the radical sign.

We have here exemplified what is equally applicable to the infinitive of all verbs, and to the words derived from or related to them.

CHAP. XI.

How Spiritual Operations, which are the object of Logic, may be explained to the Deaf and Dumb,

AFTER What has been offered in the two preceding chapters, it will easily be admitted, that there is no danger of the deaf and dumb confounding any of the parts of speech. It is sufficient for me to give, by signs, to every word its proper signification, and they assign to it of themselves its proper place; (which, by the way, is what very many, whose education has been deficient, cannot do ;) so that nothing is beyond the reach of their capacity which we propose to them with clearness and method.

To explain to them the spiritual operations which are the chief subjects of logic, I take the following measures :

I look attentively at the various rows of my library, and at the busts and the globes on the top; and I engage my pupil to fix his eyes upon them also. Afterwards I shut my eyes, and no longer beholding any of these objects externally, I trace out, however, the height and the width of them, their different shapes and their positions. 1 remark, and press upon the observation of my pupil, that it is no longer the eyes of my body which perceive them, but that I behold them in another way, as if there were two apertures in the middle of my forehead, through which these objects were still pictured in my head, my eyes being shut.

This I call Seeing with the eyes of the 'mind.' No deaf and dumb person will fail to put this to the proof in themselves, upon the spot; and they will all take pleasure in multiplying and diversifying exemplifications.

I am at Paris in my own house, giving
