It is a disputed point how these growths are occasioned. However, no compliment is paid to the veterinary science, when it is asserted that, even to this day, no recognized plan of treatment for polypus has been laid down. Such tumors are allowed to be removed with the knife, by ligature, by traction, and by tortion; in short, as you please. The first has generally been employed after a most butcherly fashion, slicing a piece off one day, and taking a morsel the next, till by slow degrees the whole was extirpated. So barbarous an operation is only worthy of ancient farriery; the blood lost must be enormous, and the subsequent weakness of the animal must more than counterbalance any benefit which the operation could have promised. Mr. Varnell, assistant professor at the Royal Veterinary College, lately removed a growth of this kind in a much more surgical fashion. That gentleman had a knife made with an angular blade; by employing this instrument, he was enabled to excise the tumor with a single cut, inflicting little pain, but affording immediate and lasting benefit to the creature. Where it can be employed, Mr. Varnell's angular knife is to be recommended, as the quickest and most efficient means of eradication which the public possess. [Illustration: POLYPUS FORCEPS OR SCISSORS.] Tortion is more repulsive in appearance than in reality. A pair of scissors having sharp curved claws, at the expanded ends of blunt blades, are employed. The tumor is seized by the claws, a little pressure is made, and, at the same time, the scissors are drawn slightly forward. By that means the points are driven into the substance, and a firm hold is obtained. The handles of the scissors are next fastened together with wire, or not, at the pleasure of the operator. The scissors are afterward made to revolve several times, and with each revolution they oblige the polypus to turn upon its pedicle, which motion first twists and ultimately ruptures it. The growth is thus removed; as the polypus is not very sensitive, and the operation should be soon over, small suffering is inflicted, when compared with the permanent ease which the proceeding insures. Of the operation by traction or dragging away, no notice will be taken; it is a vulgar and a cruel affair. Ligature, however, where it can be used, is generally preferred; because the employment of it is not so sudden, and, consequently, not apparently so violent; because no blood generally follows the removal, and therefore there is no visible evidence of pain. The writer is not certain it is the least painful of the methods proposed; the relief is delayed, although the appearance and the appetite of the animal are assurances that nothing approaching to agony is inflicted.
