508 Construction of Ancient Mexican Terra-cotta (May, 
outside while the clay was in a semi-dry condition. A hollow in- 
strument seems to have been used for this purpose, leaving here 
and there small ragged edges of clay adhering to the interior of 
the barrel around the edge of the circular perforations. The bell, 
Fig, 4 F, is concave exteriorly, of circular form, and decorated 
with designs of unique patterns which have been stamped thereon 
by terra-cotta forms or dies. The internal portion of this bell is 
hollow, becoming convex as it approaches the edges, and con- 
tracting at the point of connection with the tube or barrel toa 
thickness of half an inch. Around this is formed a small cup- 
like cavity, Figs. 9 y, 10 y, which bears a most important part in 
manipulating the instrument. It can readily be seen, by an ex- 
amination of the careful drawings shown in Figs. 9 y, 10 Y (Plate 
XIX), that these are not accidental formations, as has been sug- 
gested, but have been adapted to the form of the finger ends 
serve a particular purpose, viz., that of finger-stopping the bell. 
The necks, Figs. 8 N, 4 N (Plate xix), and clay reeds, Figs. 4 ©, 
2 A, 5 C R (Plate xrx), of these four-holed flageolets, have been 
modeled in the same manner as those upon the pitch-pipes, * 2 
cepting that forms of greater length were required on account of 
‘ the elongation of the mouth-piece. 
The instrument shown in Fig. 4 (Plate x1x), viewed in front, 
quite broad at the commencement of the mouth-piece, Fig. 4 
(Plate x1x), contracting slightly as it approaches the division of the 
neck-flap, Fig. 4, N, F, and then expanding to its greatest ee 
ness opposite the sound-hole, Fig. 4, S, where the pone 
body portion have been joined together (see section Fig: 5, P 
xIx). From the sound-hole it gradually contracts until the a 
of junction with the bell is reached, Fig. 3, G, from thence g% 
ually increasing in size until near its lower portion (i s sng ng l 
proper), when the expansion and curvature is quite rapid, nie

at last, a flat plane upon its outer edge. Viewed #3 prema re 
3, N, the neck is quite delicate, and like the reed 1D er de 
5, C, R (Plate xıx), gradually growing larger as the mido 
body, Fig. 8, M (Plate xrx) is reached. A gradual “gaol 
above downwards here unites the mouth-piece with : = 
which tapers gradually from this point until its junction :
