3. LIMITS TO PHYSICAL ACCURACY.

For all *practical* purposes, in reference to the Asiatic languages, I think that
the use of Sir William Jones's alphabet, with a few modifications, perhaps as indi-
cated below, will be sufficient even as a *phonetic* medium for the aboriginal Indian
languages, Tibetan, &c., although a most detailed transliteration is in general necessary
for *philological* questions.¹ In some instances a phonetic transcription, with even more
minute distinctions than the native alphabets will allow of, may be desirable for
ethnographical considerations. A perfectly accurate *physical* distinction between all
the modifications of vowels, and particularly of consonants, really existing, is an object
which comparative philology has as yet not taken up. Such an inquiry may be highly
interesting as regards physiological ethnography, though the distinctions would be
decidedly too minute for practical use. Sufficient accuracy can only be attained, it
seems to me, when such questions can be connected with a graphic representation of
sound. Thus, the vibrations of a membrane against which one is speaking might
communicate themselves to a mechanical hand registering their motion on a sheet of
paper which is passed along by clockwork. Several experiments of the kind have
already been made, but as yet without the success anticipated.²

Even in the languages possessing the most rational orthography, the distinctions
made are not complete. This soon becomes apparent when we attempt to define the
sound more closely by the assistance of physical experiments, such as the application of
acoustic tubes to the larynx, the prolongation of sound for decomposing diphthongs, &c.
In the first volume we have already had occasion to mention the respective experi-
ments made with the munshi in Professor Brücke's³ laboratory, when, on our return
