Imperforate tube near cloaca. Polypus: snare and twist off. Egg impaction: from atony, inflammation, stricture, congenital smallness, exhaustion, large eggs, thick end first, broken egg. Symptoms: mopes alone, feathers erect, wing and tail drooping, large, solid swelling around anus and abdomen. Rupture into abdomen. Treatment: oil cloaca and oviduct, manipulate, turn, break egg and scoop out, incise and extract, antiseptic oils. Excision of ovary. _Imperforate oviduct_ usually occurs in the lower part of its course, the tube being connected with the cloaca by a short, fibrous cord. In the case of a very valuable bird it may be incised and the walls of the duct may be brought down and fixed to those of the cloaca. _Polypi of the oviduct_ may seriously impede laying, and start obstruction and impaction. The seat of the tumor having been ascertained, it may be seized and twisted off by a snare. An elastic wire is passed through a small metallic tube so that a loop protrudes large enough to pass over the polypus. When fixed around the pedicle, it is tightened, and the tissues twisted through. =Egg Impaction in the Oviduct.= From weakness or lack of tone in the bird, by inflammation and loss of contractile power in the oviduct, by stricture of the duct as a sequel of inflammation or abrasion, by congenital narrowing, by weakening of the oviduct through constant laying, by excessive size of the egg, by double yolked eggs, by presentation of a large egg with its thick end first, or by an egg with broken shell, the oviduct may be rendered incapable of passing the egg on and out, and as others continue to press down from above an excessive and dangerous impaction ensues. The bird refuses food, mopes around with ruffled feathers and drooping head, wings and tail. The region of the anus and in front of it hangs downward and feels firm and solid, and the oiled finger introduced into the cloaca comes in contact with the impacted mass. The bird strains violently but ineffectually and rubs its anus on the ground. The swelling goes on steadily and rapidly increasing, and the bird becomes more prostrate and hopeless. Sometimes the overdistended and congested oviduct gives way and the eggs escape into the abdomen. Reul has counted as many as 24 eggs that had thus escaped into the abdominal cavity. Or without rupture of the oviduct, the soft eggs pack together into a solid, dry yolk-like mass, the watery parts having been pressed out or absorbed. In bad cases this may weigh 1½ lb. in the hen (Weber). In the way of _treatment_ the cloaca and oviduct should be thoroughly lubricated with a bland oil, which might be injected with a syringe, so as to pass it, if possible, around the impacted egg or mass. By careful manipulation the egg may now be brought away. If the thick end is presented it is sometimes possible to turn it so that the thin end will come first. Should all fail the egg may be
