whistle may be made to produce a variety of sounds by the addi- 
tion of finger perforations. It also resembles them in its powers 
of producing different sounds, of a higher pitch, by blowing 
with unusual force.” 
As the manipulation of the ancient Mexican pitch-pipes of 
terra-cotta has never been fully described, some details upon the 
subject will’ be necessary. - It has been mentioned in a former 
article that the clay pitch-pipes which stand in the scale of E flat, 
may be played singly or in quartette. The single manipulation was 
accomplished by the well-known soloist on the Baehm flute, Pro- 
fessor J. S. Coxe (who having arranged the pitch-pipes in a card- 
board frame like a mouth organ), was enabled to play thereon 
numerous simple melodies. By this means results were obtained 
(by one performer) like those produced by four persons manipu- 
lating them alternately (holding one in each hand). A record 
as been kept of these manipulations by numbering the whistles 
from tonic to octave ( 1-8), and as a ninth, eleventh and twelfth 
exist (alto a double whistle) the numeration was extended to 
twelve. As it is necessary, in producing certain intervals and 
melodies, to close the stop-holes upon some instruments, leaving 
them open in others, the black dot placed alongside of the num- 
bers or letters indicate closed stop-hole, and the naught open 
stop-hole, The different signs or modulations for the blowings, 
‘own in Figs, ABCD (Plate XVIII) signify blow evenly (Fig. A 
“ign thus — turned upward) and blow hard, (Fig. B ~ turned 
downwards) 
ett it is necessary to blow very hard, double modulation signs 
in (turned upward). In blowing soft, and vice versa, in blow- 
vii hard (turned downward). By this means a method of pro- 
a 'S obtained by which all confusion can be avoided, and the
