pig, croton beans,) with chloral-liydrate and ergot ; bleed 

 from tbe temporal artery and jugular vein, and follow up

ESTFLAMMATION OF THE SPINAL COED. MYELITIS. 



SPINAL MENINGITIS. 



The causes are similar to those of phrenitis. The dis- 

 ease may show itself by paroxysms of convulsions, with 

 exalted temperature, increased circulation and rapid 

 breathing, finally merging into paralysis ; or it may be 

 manifested at once by palsy without previous spasms, but 

 with coldness, and usually dryness, of the paralyzed part, 

 though the anterior part of the body may be bathed id 

 perspiration. There may be tenderness on striking th(. 

 spines in the affected region of the back, and there is 

 great pain and unsteadiness in any attempt at movement 

 even though the patient may be able to stand. There is 

 no redness of the uriue as in azotoemia. 



Treatment. Apply cold water or ice to the affected 

 part of the spine ; cup or leech, if this can be done ; purge 

 as in phrenitis, adding ergot of rye or chloral-hydrate. As 

 improvement sets in blister the back (cantharides, mus- 

 tard, etc.,) and give diuretics, chloral-hydrate, bromide of 

 j)otassium, ergot of rye. Care must be taken to turn the 

 patient often if unable to stand, giving a soft dry bed, and 

 to draw off the water frequently wixh a catheter unless it 

 is passed spontaneously.

Inflammation of the substance and coverings of the
