On an early system of stenography, specifically devised for the Spanish phonetics. The author, a member of the Economical Society of Madrid and of the Academy of San Fernando, proposes a syllabic system of transcription, whereas the systems previously elaborated were literary. In the introduction the author discusses in detail the stenographic methods elaborated in England and France and their drawbacks concerning their application to the Spanish language. The last paragraph discusses the form of the pens conceived by Marti for his tachygraphic system. These pens are depicted on plate 12. Of this title several editions as well as a translation into Portuguese were published.
