Should, however, the discharge be fetid, the conclusion will be that the foetus is dead, and must be got rid of, and that as speedily as possible. Bleeding may even then be requisite if much fever exists; or, perhaps, if there is debility, some stimulating drink may not be out of place. In other respects the animal must be treated as if her usual time of pregnancy had been accomplished. Much may be done in the way of preventing this habit of abortion among cows. _The foetus must be got rid of immediately._ It should be buried deep, and far from the cow-pasture. Proper means should be taken to hasten the expulsion of the placenta. A dose of physic should be given; ergot of rye administered; the hand should be introduced, and an effort made, cautiously and gently, to detach the placenta; all violence, however, should be carefully avoided; for considerable and fatal hemorrhage may be speedily produced. The parts of the cow should be well washed with a solution of the chloride of lime, which should be injected up the vagina, and also given internally. In the mean time, and especially after the expulsion of the placenta, the cow-house should be well washed with the same solution. The cow, when beginning to recover, should be fattened and sold. This is the first and the grand step toward the prevention of abortion, and he is unwise who does not immediately adopt it. All other means are comparatively inefficient and worthless. Should the owner be reluctant to part with her, two months, at least, should pass before she is permitted to return to her companions. Prudence would probably dictate that she should never return to them, but be kept, if possible, on some distant part of the farm. Abortion having once occurred among the herd, the breeding cows should be carefully watched. Although they should be well fed, they should not be suffered to get into too high condition. Unless they are decidedly poor and weak, they should be bled between the third and fourth months of pregnancy, and a mild dose of physic administered to each. If the pest continues to reappear, the owner should most carefully examine how far any of the causes of abortion that have been detected, may exist on his farm, and exert himself to thoroughly remove them. An interesting paper upon this subject may be found in the Veterinary Review, vol. 1., p. 434, communicated by Prof. Henry Tanner, of Queen's College, Birmingham, England. As it suggests a theory as to the origin of this disease which is, to say the least, quite plausible, we transfer the article:-- "I shall not go into any notice of the general subject of abortion, but rather restrict my remarks to a cause which is very much overlooked, and yet which is probably more influential than all other causes combined. I refer to the growth of ergotized grass-seeds in our pastures.
