Gutta, in Architecture, are ornaments in the form of little cones used in the Doric corniche, or on the architrave underneath the triglyphs, representing a sort of drops or bells.

Gut-tie, a disease incident to oxen and male calves at the time of castration. In the county of Hereford, those who breed cattle open the scrotum of their calves, and forcibly extract the testicles with their teeth, in consequence of which every vessel is ruptured belonging to these parts. The vasa deferentia are separated from the testicles, and form a kind of bow from the urethra, where they are united to the transverse muscles. The jejunum is the part of the gut that is tied, where it turns from the right to the left, and from the left to the right. At the bow of the gut hangs over the vasa deferentia, a hitch is formed over the bow of the gut, analogous to what is made by a carter over his cart line. In this manner an obstruction is occasioned in the bowels, which terminates in a mortification, commonly proving fatal in the course of four days.

The symptoms which attend a gut-tie resemble those of an incurable colic, or mortification of the intestines. To ascertain the distinction between the gut-tie and the colic, the hand and arm of the operator ought to be oiled, in which state it should be introduced into the anus. Here the string will be found united to the muscles, and without occasioning any pain to the animal, may be traced with ease to the stricture by the hand.

Mr Harris, farmer at Wickton, informs us, that the gut-tie may be prevented by the following simple and easy method of castration. "Open the scrotum, loosen out the testicles, and tie the several vessels with a waxed thread or silk, or sew them with a hot iron, to prevent their bleeding, as in the common way of cutting colts. This method can never displace the vessels of the bladder, testicles, kidneys, or intestines; all of which remained covered or attached to the peritoneum, or lining of the abdomen of the beast, which renders it impossible that there should ever be a stricture or tie on the gut."
