The author has been, for several years, engaged in a warfare against the use of the lancet in the treatment of the various diseases of animals. When this warfare was first commenced, the prospect was poor indeed. The lancet was the great anti-phlogistic of the allopathic school; it had powerful, talented, and uncompromising advocates, who had been accustomed to resort to it on all occasions, from the early settlement of America up to that period. The great mass had followed in the footsteps of their predecessors, supposing them to be infallible. Men and animals were bled; rivers of blood have been drawn from their systems; yet they often got well, and men looked upon the lancet as one of the blessings of the age, when, in fact, it is the greatest curse that ever afflicted this country: it has produced greater losses to owners of domestic animals than did ever pestilence or disease. A few philanthropic practitioners have, from time to time, in other countries, as well as in this, labored during their life, and on their death-bed, to convince the world of the destructive tendency of blood-letting in human practice; but none that we know of ever had the moral courage to wage a general warfare against the practice in the veterinary department, until we commenced it. We have met with great success, and have given the blood-letting gentry who practise it at the present day ("just to please their employers or to make out a case") a partial quietus: in a few more years, unless they abandon their false theories, their occupation, notwithstanding their pretensions to cure _secundum artem_, will, like Othello's, be "gone." But we are not writing for doctors. Our business is with the farmers--the lords of creation. The former are mere lords of pukes and purges; they, like the farmers, have the materials, however, to mould themselves into men of common sense; but the fact is, they are hide-bound; they want a national sweat, to rid their systems, especially their upper works, of the theories of Sydenham and Paracelsus, which have shipwrecked many thousands of the medical profession. They shut their eyes to the results of medical reform, and cling, with all their soul, and with all their might, worthy a better cause, to a system that "always was false."
