The comparative rarity of flexor rigidity of the lower extremities in cases of epidemic encephalitis would alone justify a report of two cases showing this deformity. However, our main object is to explain the mechanism of production of the foot deformity of the syndrome of dystonia musculorum, (1) by various distinct muscle groups, and (2) by the two very different processes of contraction and of contracture separated and differentiated one from the other by means of ether anesthesia. Hitherto these deformities have not been decipherable in terms of any stereotyped postures. We shall endeavor to show that this may easily be done.

ONSET AND DEVELOPMENT OF EXTENSOR RIGIDITY OF THE LOWER EXTREMITIES  Both cases were instances of epidemic encephalitis in young girls eventually showing the clinical picture of dystonia musculorum deformans.Case 1.—R. E., aged 15, complained of a cold, bronchitis and pain in the chest in October, 1919. These
