HEMORRHOIDS. 65 



The symptoms have been studied thoroiighljf by Siedamgrotzky, 

 and are as follows: Vomiting of offensive masses of meat with 

 bad-smelling muetis and sometimes bloody passages, intense thirst, 

 and high fever. Sometimes temperature subnormal, with small, 

 rapid pulse, great depression, and indifference to surroundings; or 

 convulsions, rarely violent, and sometimes recurrent, generally they 

 are continuous, and death usually follows. When a case makes a 

 recovery it is very weak a long time, and it is almost impossible 

 to get the animal to eat. 



After death the process of decomposition begins almost immedi- 

 ately, and if a [)ost-mortetn is to be made it must be made as soon 

 as possible. If this is done, the stomach will present an intense 

 hemorrhagic iaflamtnation of its walls, especially in the dependent 

 portioa, as well as severe iaflammatory changes ia the adjacent 

 organs, liver, spleen, heart, etc. 



The treatment has to be symptomatic. In the beginning give 

 an emetic (apomorphia), washing out the stomach, and direct 

 the administratioa of purgatives, emulsions of castor, olive, or 

 linseed oil. The animal should be fed on light foods easily 

 digested and in small quantities. 



Hemorrhoids. 



We mean by this name diffuse or knot-shaped (varicose) dis- 

 tentions of the posterior veins of the lower bowel at the anus. 

 According to their location, we call them external or internal 

 hemorrhoids. 



The former are located outside the sphincter ani and in the sub- 

 cutaneous connective tissue. The latter are located inside the 

 sphincter and under the mucous membrane. Sometimes these 

 enlarged veins burst and cause considerable hemiorrhage. This, 

 however, rarely amounts to anything, as the mucous membrane 

 is generally more or less inflamed all the time and often the feces 

 are coated with mucus when they are passed. It is a very com- 

 mon affection in the dog. 



Clinical Symptoms. The act of defecation is painful, the 

 feces covered with mucus and sometimes with blood — either pure 

 blood or blood and mucus mixed. On making a digital examina- 

 tion, which is very painful, the mucous membrane is found to be
