The distress becomes more and more complicated; disorganizations, alterations of the fluids, disturbances of the assimilative sphere, nervous derangements from simple illusions of the sentient sphere, and occasional trembling and twitching, to spasmodic and convulsive movements, and final extinction of nervous power, marasmus of the spinal marrow or a ramollissement of the brain; these are the consequences of such miasmatic complications.
