disease there should appear ataxia, swaying unsteady gait, and 

 staggering, there is a strong presumption of cerebellar disease. 

 This may also be manifested by the other and generic symptoms 

 already mentioned only the diagnosis is not then so certain. 

 Again cerebellar disease may exist without the ataxia and lack of 

 balance, but probably only in cases in which the progress is slow 

 and the organ has had ample time to accommodate itself to the as 

 yet comparatively restricted lesions. The result may be a mere 

 defect of muscular tone, or it may extend to an almost absolute 

 loss of contractility, or it may be of any intermediate grade. 



Treatment, which is eminently unsatisfactory, consists in im- 

 proving the general health and tone, by corroborant medicines 

 and conditions of life, and training the muscles by carefully grad- 

 uated exercise and even electricity. 



BUI.BAR PARAI^YSIS. DISEASE OF THE MEDUIyl^A 

 OBIvONGATA. 



Impaired innervation of bulbar nerves. Paresis of lips, tongue, and 

 larynx. Roaring. Rapid pulse. Glycosuria, albuminuria. Ptosis. Twitch- 

 ing eyelids. Dysphagia. Paralysis. Treatment, rest, cold to head, laxa- 

 tives, nerve stimulants, tonics, electricity. 



The bulb is intimately connected with the origin of the hypo- 

 glossal, glosso-pharyngeal, spinal accessory, vagus, facial, and tri- 

 facial nerves and active disease in the bulb is the;,refore likely to 

 entail impairment of the function of several of these nerves. In 

 man this is recognized in. chronic progressive bulbar paralysis, 

 which almost always afEects the lips, tongue and larynx advance- 

 ing steadily though slowly to a fatal termination. In degenera- 

 tive lesions there is modified voice, difficulty of swallowing, rapid 

 pulse, and laryngeal paralysis (especially of the arytenoid 

 muscles). The implication of the root of the vagus may be in- 

 ferred from the arrest of inhibition of the heart, and from glyco- 

 suria or albuminuria. Occasionally the ocular and palpebral 

 muscles are involved causing ptosis, or twitching of the muscles. 

 When the facial (7th) nerve is implicated, paralysis of one or both 

 sides of the face may be marked, including often the ears. When
