DK. D. EEEEIEE ON THE BEAIN OE MONKEYS. 
hot wires the lobes were divided and removed by a line somewhat in advance of the 
anterior extremity of the superior occipital sulcus, but the exact line was doubtful. 
The left section sloped posteriorly, the right was almost perpendicular to the tentorium. 
There was very little haemorrhage, and the operation was rapidly completed at 
11.30 a.m., the animal being almost conscious during the dressing of its wound. 
11.45m.M. The animal has been lying quietly looking about, but has not moved. 
While this note was being written the animal sat up spontaneously, but feeling weak 
and unsteady lay down again. Turned its head and looked when called by name. 
Got up and tried to walk, but staggered and fell. 
12.10 p.m. Oscillates while sitting up and totters when it tries to walk. 
Sits near the fire, rubbing its nose and ears when they become too hot. Followed its 
companion with its eyes, but cannot succeed in walking steadily to join it. 
12.20 p.m. On my approaching it and making a threatening grimace at it, it turned 
away making mouths at me as usual. A few minutes after ran away when I approached 
it, moving now almost quite steadily. 
7 p.m. Can move about freely ; but there seems to be some confusion or defect of 
vision, as the animal puts out its hand to reach things without appreciating distance. 
Can see its way, however, tolerably well. Smells at various kinds of food offered to it, 
but refuses to eat. Refused tea, of which it formerly was very fond. Objects to being 
disturbed, and sits hugging its companion, which it occasionally salutes with a tug or a 
bite when it does not sit quiet. 
March 19 th . — 10 a.m. Refused all food. Looks rather dejected, but otherwise is well, 
retaining its muscular powers and sensation unimpaired, with the exception of slight 
defect in vision, as above noticed. 
The wound looks healthy, and the animal vigorous. 
11.15 a.m. Licked at a piece of orange offered it, but will not eat any thing else. 
Frequently treats its companion to a rough shake or bite. 
5 p.m. Still refuses to eat or drink. Has taken nothing since the operation but the 
piece of orange. 
March 20 th . — 9 a.m. Still refuses food or drink. Sits quietly and takes little or no 
interest in its companion, which runs about. 
Otherwise there is no change in the symptoms, as to motion or sensation. 
7 p.m. Drank eagerly a large quantity of water. Refused all kind of food. 
March 21st . — 11 a.m. The animal is well and in seemingly good health. The wound 
is oozing only slightly at one part, the greater part having healed up. 
Came out of the cage when the door was opened and walked to the fire, before which 
it sat down with a contented grunt. Still refuses to eat. 
1 p.m. Greedily accepted and ate a piece of orange, which is the only thing it seems 
to have any desire for. Incidentally it was observed to seize hold of its companion 
(a male) and make the movements of coitus. This occurred twice. (The testicles 
existed, but the penis had been amputated.)
