If a normal person be requested to place onefoot on a chair in front of him he does so by simul-taneously flexing his hip and knee; a patient withcerebellar ataxia will, however, probably first raisehis leg by flexing his tliigh, and only later flex his knee;the two acts are not simultaneously executed.
