treated of in a distinct chapter, originally written by Mr. Quain, but 

 this is now incorporated, in substance at least, with the description 

 of those Muscles and Bloodvessels to which it has special reference. 

 It will be further noticed that the description of the Bones and 

 Muscles has undergone considerable change, that in both of these 

 sections a short account of the Morphology has been introduced, 

 and that in that on the Muscles the varieties have been more fully 

 described than in the previous Editions. The whole of this volume 

 has been edited by Dr. Thomson, in association with Mr. David 

 N. Knox, M.B., Demonstrator of Anatomy in the University of 

 Glasgow, and assisted by Mr. H. Clarke in the description of 

 the Bloodvessels, and by Dr. Gowers in that of the Cranial Nerves. 



In the Second Volume the section on General Anatomy and the 

 chapters on the Heart, the Respiratory, Vocal, Digestive, and 

 Urinary Organs, and the Organs of the Senses, have been revised 

 throughout, and in certain parts re-written by Dr. Sharpey, in 

 association with Mr. Schafer, by whom, it is right to state, the task 

 has in large measure been performed. The Section on General 

 Anatomy was completed and printed off in October, 1874. The 

 account of the Brain and Spinal Cord has been carefully revised 

 with especial regard to intimate structure, by Dr. Gowers, Assistant 

 Physician to University College Hospital. Lastly, Dr. Thomson, 

 who has revised the description of the Reproductive Organs, has 

 contributed a chapter on Embryology, with which the second volume 

 concludes. In this it has been his object to give, in such a form as 

 is suited to an elementary work on Human Anatomy, a short 

 general view of the Development of the Embryo, and of the Forma- 

 tion of the Membranes and the Placenta ; and with this there is 

 now brought together into one place the special history of the 

 Development of the Several Organs of the Body which in the 

 previous Edition was distributed throughout the work.
