1 6 THE COMMON COLICS OF THE HORSE 



lies up much closer to the spine than its fellow on the 

 opposite side. 



A knowledge of the situation and position of the various 

 abdominal organs is essentially necessary to the surgeon, 

 for he may at any time be called upon to perform opera- 

 tions in their vicinity. Take, for example, the simple 

 one of ' puncturing the bowels,' in performing which, by 

 entering the trocar too high up on the right side, the 

 duodenum or right kidney may be wounded, or the left 

 side of the spleen or the left kidney. Such serious com- 

 plications, liable to arise out of even a simple operation, 

 can only be averted by a clear and certain acquaintance 

 with the anatomy of the viscera. It is particularly 

 important to know the position they occupy in the living 

 body ; having to this end arbitrarily divided the abdomen 

 into the various regions before noticed, we will conclude 

 this chapter by stating, in tabular form, the contents of 

 each.
