Let us now examine some of the symptoms, which have been alreadyreferred to, more in detaiL Motor Paralysis (of spinal origin) may assume one of four varieties: (1) Hemiplegia—where one lateral half of the bodj^ is affected withmotor paral3sis. (2) Paraplegia—where the lower half oi the body is affected withmotor paralysis. (3) Hemi-paraplegia—where the loicer half of one lateral half ofthe body is affected with paralysis of motion. 23 354 LECTUKES ON NERVOUS (4) Paralysis of special nerve-roots (spiiuil-nerve paralysis). The SENSORY PHENOMENA, wliich iiiav 1)6 pro-duced by lesions of the spinal cord, or of the posteriornerve-roots, include the following:— (1) Pain—usually of a peculiar kind (see loco-motor ataxia, and the various focal lesions of the cord). (2) Hype7sesthexia,or increased sensibility of parts. (3) Numbness, or a sense of tingling (as if tiiel)art were asleep). (4) Sense of coldness or of heat in some i)art ofthe body. (5) Ansesthesia. or loss of sensibility. It may becomplete or partial and be limited to the aj^precia-tion of pain, touch, or temperature by the patient. (6) Delayed sensation (see locomotor ataxia). (7) Formication, or a feeling likened to thecrawling of ants over the bod}. Among the remaining symptoms which are of valuein the diagnosis
