The advantages which appear to result from the employment of this mechanical notation, are to render the description of machinery considerably shorter than it can be when expressed in words. The signs, if they have been properly chosen, and if they should be generally adopted, will form as it were an universal language; and to those who become skilful in their use, they will supply the means of writing down at sight even the most complicated machine, and of understanding the order and succession of the movements of any engine of which they possess the drawings and the mechanical notation. ... I have myself experienced the advantages of its application to my own calculating engine, when all other methods appeared nearly hopeless.
