wash the exposed portion of the oviduct with warm water, 

 apply carbolated vaseline or lard, and return to its normal 

 position by gentle pressure. In addition, it is well to give the 

 fowl 3 to 5 drops of fluid extract of ergot. 



If a chicken has chicken pox, which is invariably accom- 

 panied by diptheritic roup and canker, the first symptoms 

 are : a watery eye and an eruption appears as round, oblong, 

 or irregularly shaped nodules from the size of a pinhead to 

 that of a pea or a hazelnut. They are seen especially about 

 the beak and nostrils and on the comb, the eyelids, the wat- 

 tles, and the ear lobes. In some individuals, and particularly 

 in pigeons, the eruption is more generalized and is found on 

 the skin of other parts of the body, as the neck, under the 

 wings, on the rump, and about the vent. Here the nodules 

 may become larger than on the head. 



The nodules begin as small red or reddish-gray deposits 

 with a shiny surface, and gradually enlarge, while the color 

 changes to a yellowish, brownish, or dark brown, and the 

 surface dries and becomes shriveled, uneven, and warty in 

 appearance. Owing to the number of nodules and the ex- 

 tension of the inflammation, large patches of skin become 

 thickened and covered with hard, dry crusts, closing the 

 nasal openings or the eyelids and making it difficult even to 

 open the beak. 



In the milder cases the eruption is limited to the head, the 

 nodules are distinct and small, and the general health of the 

 affected bird does not suffer. The nodules soon dry, heal, and 

 shrink ; the crusts become loosened and fall off, and there is 

 rapid recovery. In the more malignant cases the eruption is 

 generalized over the surface of the body, the nodules are 

 larger, and there is a diffuse inflammation and thickening of 

 large areas of skin. If the crusts are rubbed or scratched off 

 by the fowls, there occurs from the ulcerous surface a dis- 

 charge at flrst watery, but later thick, yellowish and viscid, 

 which soils the feathers and, if abundant, gives off a disa- 

 greeable odor. This type of the disease is accompanied with 

 fever, rapid loss of flesh, and prostration, and frequently 

 causes the death of the victim. In the most malignant cases 

 the eruption extends to the mucous membrane of the eyes, 

 nostrils, and mouth, causing a diphtheritic inflammation 

 that is generally fatal. 



If a chicken goes light, it may be caused from any one of 

 the following: mites, lice, intestinal worms, tuberculosis, or 

 cholera.
