5. All diseased fowls should be removed from the flock and 

 treated. 



6. The immunizing- effect of the vaccine does not take place 

 immediately ; therefore, the fowls already infected at the time of 

 vaccination or soon after will, in most cases, develop chicken-pox 

 lesions. Such cases are usually very mild and will soon recover 

 if the fowls are removed from the flock and the lesions treated. 



7. The hypodermic needle should be inserted just under the 

 skin and not in the muscle. 



TREATMENT. 



Of the various kinds of disinfectants recommended for the 

 treatment of this disease tincture of iodine has been found to be 

 the most satisfactory. The scabs which form on the sores of the 

 comb, wattles or skin should be removed with a dull knife or with 

 the nails, and tincture of iodine applied to the exposed surface. 



Collections of exudate on the mucous membrane of the mouth 

 should be removed with forceps or a scoop and the exposed 

 membrane treated with tincture of iodine. All collections of 

 exudate within the eyelids can usually be removed by pressing 

 with the thumb and finger tips around the eye. If any of the 

 exudate should adhere to the eye it should be removed with 

 forceps and it may sometimes be necessary to use forceps also 

 in removing the exudate from beneath the third eyelid at the 

 inner corner of the eye. Afterwards drop a small amount of tinc- 

 ture of iodine into the eye. 



The tincture of iodine can be applied most conveniently in all 

 cases with a medicine dropper. Treatment should be repeated 

 as often as the scabs or exudate reform. Any fowl that does not 

 show a marked improvement in condition after three or four 

 treatments will usually recover very slowly. In such cases, unless 

 the fowl be very valuable for show, breeding or other purposes, 

 it is more economical to destroy it than to give further treatment. 



Collections of exudate within the nasal cavities always produce 

 marked swellings of the face. This condition is relieved by 

 making an incision through the skin over the swelling, removing 

 all the exudate with a pair of forceps or scoop, and then packing 

 the cavity with absorbent cotton saturated with tincture of iodine. 

 The cotton pack is necessary to keep the incision through the skin 

 from healing too rapidly. If not packed, the wound will quickly 

 heal, the exudate reform, and no benefit be derived from the opera- 

 tion. The pack also assists in controlling the hemorrhage, which 

 is always severe. When the hemorrhage is unusually severe, it 

 should be checked by the application of a strong caustic, such as 

 silver nitrate. The cotton pack should be removed, the wound 

 cleansed and a new pack put in every two or three days as long 

 as the exudate continues to form. When, upon removal of the
