“With reference to the published works of Fritsch and Hitzig on the motor centres of the cortex, and also (while I am engaged in the same studies) concerning the experiments of Hermann on electrical stimulation in Pflüger’s Archives, Vol. X., I feel called upon to make the following communication:--(1) In newly-born dogs no muscular movements were observed during electrical stimulation of the cortex cerebri; (2) These movements were only observed some days (9-11 days) after birth; (3) The extent and form of the motor centres of the cortex vary; in young animals they differ from those of fully grown animals. The necessary subjects for further experimentation (pregnant bitches and young dogs of all ages) are difficult to obtain so that the experiments only proceed slowly.
