Symptoms'. This afEection is common in heavy draft horses of 

 a lymphatic temperament and kept on high feeding and at hard 

 work. It rarely develops however while the subject is kept at 

 steady work. But if, in the midst of such work, the horse is 

 kept at rest in the stall over one, two, or more days on the same 

 generous diet, he is found shivering violently, with rapid, labored, 

 breathing, high pulse and elevated temperature, symptoms which 

 have been frequently mistaken for those of pneumonia. There is 

 complete anorexia, and often ardent thirst. The patient is indis- 

 posed to move and if forced to it shows lameness in one hind limb 

 with an extraordinary abduction of the limb at each step, and 

 sometimes so severe as to prevent his putting his full weight upon 

 it. If an examination is now made high up in the groin close 

 outside the inguinal ring, the lymphatic glands will be found to 

 be swollen, hot and tender, so that under even moderate pressure 

 the leg will be lifted and abducted until the patient threatens to 

 fall on the other side. 



A little later the shivering may have given way to the hot stage, 

 with it may be general perspiration, and the swelling may have 

 extended down the course of the saphena vein and lymphatics, 

 as a distinct ridge and the lower part of the limb from the foot to 

 the hock may be filled, dropsical and hot. Unless checked the 

 swelling goes on increasing till the lower part of the limb is two
