The mucous surfaces aresimilarly affected. The analgesia may be partial or com-plete, and usually conforms in outline ina general way to the thermo-anesthetic area, or it may be more embraces all the tissues, so that felons, caries of bone, and disinte-grating joints may be painless and insensitive. As a general rule, tactile or epicritic sensibility is perfect. A slightdiminution of it is not inconsistent with the diagnosis, and its oblitera-tion follows extreme invasion of the posterior columns, being then a.

An anestheticarea may thus have a border of thermo-anesthesia and analgesia, or theseconditions may be found in different parts of the body, in relation tothe amount and distribution of the cord disease. In some cases and atearly stages pains of a tabetic, neuralgic, or burning sort are patients complain of a constant warm or burning sensation in agiven region. As a general rule, deep and protopathic sensory featuresare more involved than the superficial or epicritic. Thus, sensitivenessof joints, of the testicle, and eyeball is often blunted or abolished. Motor disturbances are dependent largely upon the invasion of theanterior horns and the pyramidal tracts. They are, therefore, usuallysecondary in point of time to the sensory symptoms with which they cometo be associated. As the ante
