In respect to the forms and voices there are those that are different, believing the owner will have arrived to know that they haven't been available until today, according to as it has demonstrated with the obtained results in the practice sessions publicly verified by distinguished professors, and by the spontaneous testimonials, that have been dispensed in the daily newspapers, as well as by the works presented in the Exposition.
