In this new edition of the late Professor Hughes's Handbook on the Nerves of the Body, the letterpress has been rewritten and enlarged, while new blocks have been made from the plates of the original edition.

The old terminology has been adopted through the text. Where these terms differ materially from the B.N.A. the latter have been placed within brackets.

The author desires to thank Dr A. Walker for his valuable assistance in reading the proofs, and for compiling the Index.

Charles R. Whittaker.
