Another huayra-puhura ([Fig. 19]), likewise still yielding sounds, was discovered placed over a corpse in a Peruvian tomb, and was procured by the French general, Paroissien. This instrument is made of soapstone, and contains eight pipes. It now belongs to the Rev. Canon J. H. Rawdon.[4] In the Museum may be seen a good plaster cast taken from this curious relic. The height is five and three-quarter inches, and its width six and a quarter inches. Four of the tubes have small lateral finger-holes, which, when closed, lower the pitch a semitone.
