Originally published in 1937, this book is a practical manual of Kanuri which will be of use to both the layman and the linguist. This analysis makes it clear that kanuri is a tone-language and the author urges the reader to observe the tone-system of the language so that the accidence can be fully understood, as grammatical tone sometimes forms an integral part of it. As this is a practical study, a practical orthography has been chosen - i. e one that uses only letters that are absolutely necessary. This system improved Kanuri orthography, as it was based on scientific principles.
