vi PREFACE TO FIFTH EDITION 



and F. M. Halley for other dissections upon which they 

 have expended time and skill, and which have been used 

 in the preparation of the new illustrations. 



I wish also to thank Professor Arthur Thomson for per- 

 mission to use the illustrations of his beautiful dissections of 

 the eye ; Professor A. M. Patersori for permission to use two 

 diagrams illustrating the connections of some of the cranial 

 nerves ; and Dr. Logan Turner for the loan of the specimens 

 from which the illustrations of the dissection of the mastoid 

 region and middle ear were made. 



All the new illustrations are from drawings made by Mr. 

 J. T. Murray. They are characteristic of his excellent work, 

 and I am indebted to him for the care and skill he has ex- 

 pended on their production. 



The new indices and the glossary are the work of Mr. J. 

 Keogh Murphy, F.R.C.S. I believe they will prove to be of 

 great service ; and I desire to thank him not only for the 

 time and trouble he has spent upon them, but also for many 

 useful suggestions which he has made during the progress of 

 the work.
