DE. D. EEEEIEE ON THE BE A IN OE MONKEYS. 
On being placed on a chair it gave evident proof of its retention of sight by jumping 
on to the table, and running to a dish containing milk, and drinking up the contents. 
There is distinct reaction on both sides when a hot iron is applied to the skin. The 
animal starts, and rubs vigorously the part touched. 
The extent of its hearing and smell were not ascertained at this time. 
January 28 th . — 10 a.m. The animal is alive and well. Ate its breakfast as usual. 
Can walk and jump about, and sees distinctly, as it puts out its hand and lays hold of 
objects before it. 
In order to ascertain its condition as to hearing and smell, the right nostril and the 
left ear were tightly stopped with cotton-wool. 
When offered a piece of apple it hesitated eating it, placing it to its nostrils over and 
over again, apparently as if it had difficulty in smelling. 
Does not pay any attention when a noise is made, such as formerly caused it to 
respond actively. 
Tactile sensation seemed unimpaired on both sides. 
5 p.m. The left side of the scalp has become oedematous. The left eye is partially 
closed by oedema of the eyelids. Eats heartily. 
Took a piece of apple offered it in its left hand. 
On testing the right side by means of the hot iron there was a marked diminution of 
reaction on the ear, hand, and foot of the right side, as compared with the left. 
Sight continues unimpaired. Smell and hearing are considered as impaired ; smell 
on the left, and hearing on the right. It is difficult to ascertain by any crucial test 
whether they are gone on these sides. 
January 29 th . — 10 a.m. The eyelids are cedematous. Ate some breakfast. When taken 
out of its cage sat still, unwilling to move. Takes every thing offered to it in its left 
hand. The animal drinks out of a dish, holding its head sideways, keeping the left side 
of its lips in contact with the fluid. 
On testing with the hot iron there is very marked diminution of reaction over the 
whole of the right side of the body as compared with the left. 
There is no loss of muscular resistance in the limbs of the right side. They do not 
hang flaccid as in motor paralysis. There is no facial distortion. 
The limbs are occasionally moved, but they are not used by the animal in grasping 
or progression. 
The foot and hand are frequently rested on the floor in irregular and what otherwise 
would be uncomfortable and unnatural positions. 
The animal occasionally scratches its left side with its left hand. Occasionally utters 
a discontented grunt. Retains its intelligent look, and takes notice of what is going on 
around it. 
It was killed with chloroform at 11.15. 
Post mortem Examination . — The scalp was cedematous and the wound suppurating. 
From the opening in the skull a hernia cerebri of the diameter of a walnut was observed.
