Among other observations which escape the ordinary rules of assimilation or weakening are those lately studied in the book of Meringer and Meyer on Faults of Speech, in the shape of metatheses, contaminations, articulations, etc., one class of which consists in the interchange of consonants by shifting them from the syllables to which they belong to others, so that the displaced consonant takes the position of the one that has displaced it. Such steps taking place in an idiom without literature or education are as contagious as the others. It is in this way that the root spek, which gives the Latin spectare and the Sanskrit spak, is in Greek σκεπ, whence (σκέπτομαυ, σκοπός, σκοπέω), and in French the Latin scintilla, which should make échintelle, has given étincelle. The vocal image has been reversed.
In the laboratory of experimental linguistics which has been instituted in this college, these phenomena of phonetics will be subjected to a scientific study, the articulations of individuals will be examined at the moment they are made in the mouth; and by means of the instruments of Edison and Marey we shall be able to write the sounds, or rather they will write themselves, so that they will offer to the minute and protracted observation of the eye what the ear necessarily perceived in a confused and fugitive way; and thus a whole order of research and discovery is opened to linguists, however little taste they may have for physics and the natural sciences.—Translated for the Popular Science Monthly from the Revue Scientifique.
