viii PREFACE TO THE SECOND EDITION 



alone. He now has corroborative testimony. In this 

 connection, seeing that it is more or less a summary 

 of the arguments both for and against the stimulant 

 treatment, I may point out that I have now included in 

 the Appendix (Part II.) an article on ' The Use and 

 Abuse of Sedatives in the Treatment of the Equine 

 Colics.' 



Regarding the other additions, perhaps the most 

 important is that of Chapter X., on ' Subacute Obstruc- 

 tion of the Pelvic Flexure of the Colon.' This, I hope, 

 is a further step towards the clearer diagnosis of intes- 

 tinal obstructions, and I trust the matter there recorded, 

 together with the diagrams illustrating it, will lead others 

 to a comprehension of these troubles even more exact 

 still. 



To Chapter II., which deals with the surgical anatomy, 

 I have added diagrams which may, perhaps, define more 

 clearly than the words the formation of the so-called 

 cardiac sphincter of the stomach. 



Appended to Chapter VII., that on ' Gastric Tympany,' 

 there is a description and illustration of a new stomach- 

 tube, which shows piomise of being of use in the treatment 

 of both gastric tympany and gastric engorgement. 



Of alterations, there is only one of importance. It 

 deals with a change of opinion, which I should be dis- 

 honest in withholding, and will be found fully set out in 

 Part III. of the Appendix. 



In conclusion, I again commend this book to the 

 veterinary practitioner, asking him, above all, to make it 

 but an aid towards the achievement of an end w^e must 

 all of us have in view — the further elucidation of the 

 troublesome affections with which it deals.
