Foot and Mouth Disease. 369 



with these or with phenic add. The herd should be divided into 

 two lots — the apparently sound, and unsound kept strictly apart 

 under separate attendants, above all separate milkers. As soon 

 as any symptoms are shown by an animal in the sound enclosure 

 it must be instantly transferred to the other and its stall disin- 

 fected. Antiseptics such as gaseous iodine (two tablespoonful of 

 tincture of iodine, thrown into a quart of boiling water twice 

 daily), sulphurous acid, salicylic acid, creolin, lysol or other 

 ointment on the feet and teats, may also be used. In this way it 

 may be, possible to save a number from an attack, yet most com- 

 monly the expo.sure is common and universal and the malady de- 

 velops in all simultaneously. For those already attacked, gruels, 

 mashes, and cool pulped, finely sliced or boiled roots may be all that 

 is required, the disease runs its course and recovery ensues in 15 

 days. As local dressings the following may serve as examples : 

 for the mouth, borax, chlorate of potash, salicylate or sulphite of 

 soda 2 drs. to i quart water ; phenic acid, creolin, or lysol, one or 

 two teaspoonf uls to a quart ; for the foot, clean the interdigital space 

 and apply tar and carbolic acid with bandage, or use solutions of 

 creolin, lysol, pyoktanin or blue-stone ; in aggravated cases strong 

 mineral acids with tar ; for the teats, ointments of boric or 

 salicylic acid, creolin, lysol, naphthalin or napthol. Separation 

 of the hoof or mammitis will require treatment according to in- 

 dications. Mercuric chloride subcutem has been lately adopted 

 to cut short the disease.
