Preface. ix 



the proofs, and in the preparation of the index ; to Mr. W. 

 Hunting, F.R.C.V.S., for suggestions on the chapter dealing 

 with Locomotion ; and to Professor M'Fadyean for the loan 

 of two woodcuts illustrating the chapter on the Foot. 



To facilitate the study of locomotion, I have had the 

 plates so arranged as to face as nearly as possible the 

 letterpress describing the movements. 



I have laid under contribution Colin' s invaluable ' Traite 

 de Physiologie comparee des Animaux'; Ellenberger's 

 ' Physiologie der Haussiiugethiere ' ; Foster's, M'Kendrick's, 

 and Landois and Stirling's Text-books of Physiology; 

 Gamgee's translation of 'Hermann's Physiology'; the 

 same author's 'Physiological Chemistry of the Animal 

 Body ' ; Halliburton's ' Text-book of Chemical Physiology 

 and Pathology ' ; Bunge's ' Physiological and Pathological 

 Chemistry'; Meade Smith's 'Physiology of the Domestic 

 Animals,' and others mentioned in the text. With reference 

 to Dr. Meade Smith's work, I regret to find that on page 105 

 I have inadvertently given the title as 'A Text-book of 

 Comparative Physiology.' 



I have endeavoured to acknowledge all sources of in- 

 formation, though it is possible that, in drawing from such 

 a wide area, I may have omitted in places to do so.
