It should scarcely require any further proof on my part after this and all I have previously said to show that, if any of the peoples now speaking Latin tongues were in place thereof to speak English or German, they would, in the course of time, cease to be Frenchmen, Spaniards, or Italians, as the case might be, and would become Anglo-Saxons or Germans; or that, if any of the Slavonic races or peoples would do the same, the same result would eventually ensue; and also that, if Anglo-Saxon or German peoples were to speak Latin or Slavonic tongues in place of their own, they would eventually cease to be Anglo-Saxons or Germans, and would become the people whose tongue they were speaking; always provided, of course, that such tongues were to be spoken _idiomatically_ correctly. Should any one still doubt that language is the mainspring formulating peoples and nations in all that essentially belongs to them and distinguishes them as such, I confidently believe that that which I shall still further have to say on this subject will eventually convince even the most obdurate of the correctness of these assertions. The preceding schedules both for English-and German-speaking peoples show their mode of breathing during their waking moments and for the purpose of conversation. During sleep and for the demands of the singing voice, however, thorax and abdomen interchange with one another in so harmonious a manner that their inspirations and expirations appear as one respective inspiration and expiration. The following schedules will show the relation of metre and rhythm to breathing. Inspiration being of longer duration than expiration, I have in the following signified the former by the sign for long (¯), the latter by that for short (˘); while for the rise of the voice I have used the sign for acute (´), and for its fall that for grave (`); for comparison, see schedule on page 202.

In making the experiments just now under consideration, it will _not_ be necessary, after closing the muscles of the trachea or the œsophagus for the first six movements, to continue doing so, as the next six movements will ensue involuntarily. There may be several repetitions of these twelve movements involuntarily or automatically following after that; any special mode of breathing once assumed being apt to continue indefinitely until another mode is inaugurated.
