Bleeding ceases as soon as the pressure is relaxed. In the case of the external saphenous vein, the vein is raised by compressing the middle region of the limb and the vessel is opened with a lancet, a little above and towards the outside of the hock. The subcutaneous vein of the forearm can be raised by compressing the fore limb below the elbow. The vein is visible throughout the length of the inner surface of the radius, and can easily be opened with a lancet.

It is preferable to bleed with a lancet from the marginal veins of the ear, the external saphenous vein a little above the hock, or the sub- cutaneous vein of the forearm. SETONS, ROWELS, PLUGS, OR ISSUES. Although the application of setons is still practised in horses, that of "issues" has largely been given up in bovine animals, although some practitioners still regard issues as of considerable value and as producing effects similar to, or better than, those of sinapisms.
