from any cause, exposure to cold and dampness, severing the 
cord too close to the body ; but the chief cause, I think, to be 
infection from manure, urine, etc., or from other affected animals. 
There may be a specific germ causing the disease, but whether 
or not this is so, I am unable to state, never having experi¬ 
mented any in this line; but this much I am satisfied of, that an 
affected animal should not be allowed to run with others whose 
navels have not thoroughly healed. 
In the line of treatment, I rely more upon prophylaxis than 
upon curative treatment. 
As soon as a colt is foalded, I instruct my patrons to dust on 
a little iodoform and to keep them in as clean a place as possi¬ 
ble, and I have never seen a case of phlebitis occur after these 
precautions had been attended to at birth. 
Affected animals should be isolated at once and placed in 
clean, well-ventilated dry quarters. 
Antiseptic treatment is indicated throughout the course of 
the disease. If the vein is closed up at the external opening 
and puss has already formed, open freely and allow good drain¬ 
age, and syringe out with hydrogen peroxide. 
I have used both moist and dry antiseptic dressings to this 
part, but I find by experience that the dry ones are the most 
serviceable. For this dressing iodoform fills all the require¬ 
ments better than any other ; I have tried boracic and salicylic 
acids but they are hardly powerful enough. 
If a moist dressing is desired, carbolic acid in oil or in form 
of an ointment is the best one that I know of. 
Internally, I usually give aconite combined with a little bel¬ 
ladonna to control the fever, but I place more confidence in 
salicylate of sodium as a curative internal agent than any other. 
I usually give from io to 20 grains at a dose. 
When arthritis is present or threatened, I find hot applica¬ 
tions to be very serviceable, and when pus has formed I draw 
it off through a fine canula that I can connect to a large hypo¬ 
dermic syringe, and after doing so I inject into the joint a mix¬ 
ture composed of olive oil 1 § and iodoform 1 3 . This mixture
