DICTIONARY OF ORGAN STOPS. 181<br />

I u<br />

M. Kempelen, <strong>of</strong> Vienna, also succeeded in constructing an apparatus<br />

furnished with a mouth-piece, and a nose, made <strong>of</strong> two tin tubes which<br />

communicated with the mouth. When both tubes were open and the<br />

mouth-piece closed, the consonant M was sounded, and when one was<br />

closed the consonant N. Eventually M. Kempelen was able to produce<br />

entire words and sentences, such as Je vous aime de tout mon caur,<br />

Conslantinopolis, Romanorum imperator semper Augustus, Exploitation,<br />

etc. French pronunciation would, <strong>of</strong> course, lend itself more readily to<br />

artificial imitation. For a fuller description <strong>of</strong> this machine, the reader<br />

should consult Sir David Brewster's "Letters to Sir Walter Scott on<br />

Natural Magic." Mr. Willis, <strong>of</strong> Cambridge, pursuing a former experiment<br />

<strong>of</strong> M. Kempelen, obtained some very<br />

curious and interesting results. He em-<br />

ployed a reed and funnel shaped cavity<br />

like that shown in the figure. By sliding<br />

a flat cover over the top he found he<br />

could produce the whole series <strong>of</strong> vowel<br />

sounds. In another experiment Mr. Willis<br />

fitted to the reed cylindrical bodies with<br />

sliding telescope joints. Brewster sum-<br />

nu^u^uuuykuyr^ isa<br />

marizes the results as follows : " When the tube was greatly less than<br />

the length <strong>of</strong> a stopped pipe in unison with the reed, it sounded I, and by<br />

increasing the length <strong>of</strong> the tube it gave E, A, O, and U, in succession.<br />

But what was very unexpected, when the tube was so much lengthened<br />

as to be i-J times the length <strong>of</strong> a stopped pipe in unison with the reed,<br />

the vowels began to be again sounded in an inverted order, U, O, A, E,<br />

and then again in a direct order, I, E, A, O, U, when the length <strong>of</strong> the<br />

tube was equal to twice that <strong>of</strong> a stopped pipe in unison, with the reed."<br />

(Vox Inaudita—<br />

IVox Ineffabilis— (Lat.) Inauditus = unheard. (Lat.) Ineffabilis =<br />

unutterable, inexpressible.<br />

A facetious pleasantry indulged in by some mediaeval <strong>organ</strong> builders.<br />

The <strong>stops</strong> so named extended no further than dummy stop handles<br />

Sycophantic <strong>organ</strong> builders take note !<br />
