Acknowledgments
Our thanks are due to our colleague Paul Devaux, whose experimental skill and sound engineering played a major part in the successful design of the instruments described.
We finally wish to extend our thanks to the Direction des fitudes et Fabrications de 1'Armement, Paris, France, by whose permission this paper is presented.
