Inthe lower extremity the pero-neal group of muscles is morefrequently affected than anyother; next in frequency theposterior tibial; then the an-terior thigh muscles, and leastfrequently of all, the posteriorthigh muscles. The tibialisanticus is generally paralyzedin connection with the quad-riceps extensor. These muscles are supplied by different nerves, but areassociated in the extension movement of the leg during walking. The in-volvement of associated muscles in poliomyelitis would furnish the data forthe study of spinal localization if the disease led more frequently to a fatalissue and to post-mortem examinations. An entire extremity, or a large group of muscles, may be permanentlyparalyzed ; in some cases the loss of function may be restricted to a singlemuscle. There is no little difficulty at times in making out the one or moremuscles which have been permanently affected, and in a number of cases.

In addition to this retrogressive form of paralysis, whichmay at times be widely distributed and at other times curi-ously limited, we have to notice the rapidly developingatrophy of the paralyzed muscles. I have seen a markeddifference between a paralyzed leg and the other normalmember within three days of the first onset of the disease,and it is not at all unusual to recognize the wasting of thelimb by superficial inspection within the first week or wasting is developed entirely in keeping with the dis-tribution of the paralysis, and this is so true that in one in-stance, which I can rec
