The circulation in the aflPected limb is considerably impaired, andit is cold, blue and flabby, but not oedematous. In some cases thebone is subsequently hampered in its growth, so that the limb isshorter and more slender than its fellow in after life. (See Fig. 112.)

In these casesthe paralysis is soon followed by atrophy and by vaso-motor is not attended by pain or tenderness on motion, and usually de-creases to some extent, leaving the limb, however, in part permanentlyparalyzed. These two types of onset of the disease are evidently quitedistinct from one another. After the onset is over there is a slow progressive improvement upto a certain point, and then the pe
