When the notes " Kong-Kay'' are uttered, the a6tion of 
inflation has been performed by two distinct inhalations 
of air, one with its head turned to the right and the 
other immediately after to the left. At the moment of 
the utterance of the notes, the head is turned to the right 
for the u Kong," and then suddenly — so suddenly that it 
almost startles the observer — the head is swung round to 
the left for the " Kay," which is issued with a strikingly 
loud, piercing and metallic ring or clang — so loud and 
shrill indeed that, if the observer is close by, the ears are 
actually deafened for the moment by the sharpness of the 
sound. 
When, however, the sweet, musical, and deeply-toned 
bell-like notes " Do-rong" are about to be uttered, the 
bird is observed simply to hold its head forward, and to 
make two distinct gulps of air ; and then, holding its beak 
upwards and slightly extending its neck, the notes are 
rolled out, as it were, with full voice and roundness and 
resonance. 
On each occasion, as already stated, the caruncle is 
depended in a state of collapse to its greatest length 
possible, over one side of the beak. The one bird on 
which the above notes were based, I may state, was a 
fully developed male ; the second, a younger male, alto- 
gether lacked the powerand strength of note of the former, 
whose notes were to be heard at a very considerable 
distance away from the house in which it was kept, in 
spite of the ordinary confusing noises of a town.
