may bs absent, especiall}^ if the affected vein returns blood from 

 a higher level than the heart, and then the symptoms are confined 

 to the vein and its immediate surroundings. From lymphangitis 

 which shows similar hard cords, it is distinguished by the absence 

 of an extended network of diseased vessels, by the lack of a 

 diffuse, doughy swelling, and by the fact that the adjacent lymph 

 glands remain free from inflammation, pain and swelling. In the 

 more extended cases there is fever, which may be of a very high 

 type and may merge into pyaemia. In deep-seated cases it may 

 be difficult to identify the disease, but it may be suspected if in 

 the course of erysipelas or metritis there is a sudden increase of 

 fever with pain and swelling, and distension of veins leading into 

 the part. 



The treatment of idiopathic phlebitis is largely that of the par- 

 ticular infecting disease on which it depends. In simple cases 

 due to trauma absolute rest and the application of ice and anti- 

 septic solutions, or where these cannot be applied, the u,se of anti- 

 septics internally, will be indicated. Hyposulphite of soda and 

 sulphide of calcium are especially indicated. From the early days 

 of veterinary medicine, flying blisters of Spanish flies, over the 

 inflamed vein or veins have proved very successful, and under 

 the lead of Nonat the .same was in 1858 and .since adopted with 

 gratifying .success in the human subject. Abscesses formed in 

 accessible .situations should be promptly opened and treated anti- 

 septically, and swelling of the affected part should be checked by 

 elevated position, or if that is impossible, by a smoothly applied 

 bandage. Rubbing and active movement are dangerous, as tend- 

 ing to detach clots which float off to start new emboli and inflam- 

 mations in the lungs.
