138 DR. C. E. BEEVOR AND MR. V. tIORSLEY ON THE EXCITATION OF THE 
tinctly evoked by stimulating the cortex in the Oi’ang we shall arrange in the order 
in which the varieties of representation are successively grouped in the cortex from 
above down. 
Div. I. Protrusion of whole organ. Tongue flattened posteriorly, tip directed to opposite side. 
Tongue heaped up on the same side, tip directed to opposite 
side. 
Div. 2. Rolling over of whole organ Tongue rolled over to opposite side, 
to side. 
Div. 3. Retraction of whole organ. Tongue heaped up posteriorly, rolled over to opposite cheek. 
Tongue flattened throughout, the tip of the opposite side being 
retracted horizontally. 
On summing up this table it will be seen that the movements are consecutively 
arranged in the cortex, so as to pass gradually one into the other from protrusion to 
retraction. 
(12) Tongue pi-otruded, flattened posteriorly, tip directed to opposite side. —This 
occurred at squares 7, 8, 98, 99, 9, 10, II, 11'. This movement, shown in fig. 12, is 
the one tqjon the loss of which most stress has hithetto been laid in cases of 
destruction of the internal capstde and cortex in Man, but in our opinion it is but one 
and not the most important of a series of movements differing one from another, as 
will subsequently be seen. See Plate 19, fig. 12. 
(13) Tongue protruded, heaped up) on the same side, and tip directed to the oyrposite 
side. —This movement is represented next below the one just described. No. 12, and 
was noted at squares 12, 13, 14. See fig. 13. 
It was seen that by “ heaping up ” to one side (for instance, the left) the tongue 
was narrow'ed transversely, the left side being thickened in the vertical diameter, so 
that that side and border bulged upwards. 
(14) Tongue neither pn'otruded nor retracted, hut rolled over to opposite side .— 
This we found to occur at the next level below% viz., at squares 15, 16, 17. 
It is a very important movement which has not hitherto received attention. In its 
execution the same side of the tongue rose and then the whole organ was tilted up 
and I'olled over on its longitudinal axis, so that the previously horizontal dorsum 
was inclined towards the opposite cheek. See fig. 14. 
(15) Tongue retracted, heaped up posteriorly and rolled over to the opposite cheek .— 
It is clear that this movement is a further extension of the last one (No. 14) with the 
addition of retraction. It was observed at squares 20, 21, 22. See fig. 15. 
We need only add tliat the raising of the posterior part of the tongue was bilateral 
and occurred before the rolling over began. See “ Marches,” p. 146. 
(16) Tonegue retracted slightly, flattened throughout, and the tip of the opposite side 
retracted horizontally . —This rather singular movement we have never seen before ; it 
was found at the lowest point of the representation of the tongue at squares 23, 84, 
85, 86, 87, 88, 89, 90.
