COLICS OF THE SOLIPED 21 



Differentiation from Hemoglobinemia 



Let us now turn to azoturia as the one remaining 

 disease having symptoms allied to true colic to which I 

 wish at this time to call your attention. Hemoglobi- 

 nemia is typically distinctive as the disease progresses to 

 greater severity or duration, and after the paresis of the 

 crural muscles appears, and the gluteal group becomes 

 rigid and enlarged or if other groups are affected after 

 they become similarly involved. 



A differentiation may also be made through the dis- 

 covery of the typical high-colored urine ; absence of pain 

 and return of appetite, together with the history of high 

 feeding, a short rest, exercise, sudden onset and lame- 

 ness which is so consistently diagnostic. 



The primary expressions, however, in azoturia and 

 enteralgia are conflicting in many instances, particularly 

 in those cases seen during the initiatory pain or muscular 

 spasm, when the anxious and excited animal sweats pro- 

 fusely, breathes excitedly, becomes restless, lies down, 

 rolls, rises, or if unable to get up, flounders heavily from 

 place to place or side to side with accompanying con- 

 vulsive movements, quickened pulse and peristalsis ap- 

 parently suppressed through involvement of the sympa- 

 thetic nervous system. 



It is, therefore, evident that a careless examination 

 may easily lead to error that would not be made by the 

 painstaking diagnostician. 



Differentiation from Pectoral Ailments 



Pleurisy is another condition that is altogether too 

 frequently overlooked by writers who attempt to differ- 

 entiate true and false colic. The practitioner who casts
