This paper is a part of a general study of the entire cortex of the sheep brain, the motor area alone being considered in this communication. The work has been carried on under the direction of Dr. Adolf Meyer, to whom I am grateful for guidance and much valuable assistance.Marcacci,1 in 1877, outlined in the sheep brain four excitable areas: first, the center for the opposite fore limb in the posterior part of the superior frontal convolution; second, the center for the muscles of the neck, stimulation of which caused the head to pull to the opposite side and in the male, a movement simulating butting; this center he also located in the superior frontal convolution in front of that for the fore limb; third, a center for movements of the facial muscles; no mention is made concerning whether these movements occur on the same or opposite
