=NODULAR DISEASE IN SHEEP.=--Nodules resembling those of tuberculosis found in the intestines of sheep, are due to the presence of parasitic worms. Profuse diarrhœa and a pronounced anemic condition prevail. A post mortem examination of the intestines discloses the presence of numerous nodules in the intestinal walls. If the worm is present, no treatment is possible, for the reason that any medicine that would affect the worm would also affect the tissues and lead to their destruction. Prevention, therefore, is the only means of overcoming the disease. Sheep must be kept off infested pastures, and infested pastures must be plowed and given over to cultivated crops. Give lambs only clean pastures to graze over. This means crop rotation in connection with sheep husbandry. No feed that has been tramped over by infected sheep should ever be supplied to lambs or sheep not infested with the disease. =OBSTETRICS.=--Difficult parturition is common in some females. And frequently others, less bothered as a rule with any difficulty at this period, deliver their offspring only after great labor and much difficulty. When such cases occur close vigilance not only frequently hastens delivery, but often saves the life of either the mother or offspring or both. [Illustration: NATURAL PRESENTATION OF THE FOAL In either of these cases delivery follows in the usual order without delay or injury to the mother.] In many instances the trouble is seated in the womb; the neck of the womb remains closed, and even though long-continued and vigorous efforts are made, the offspring does not arrive. In cases of this kind assistance can be rendered which quickly removes the difficulty. First oil the hand and forearm and work the fingers into the passage, gently pressing it open. If the womb does not yield to this treatment saturate a sponge or cloth with extract of belladonna and rub it around the neck, leaving it thus for a little while. On removing the sponge the passage will open.
