of bis body. He expects this hand to be taken kindly , and he 
then assumes his natural attitude. In that manner of advanc- 
ing it is obviously impossible that he could bite, as his mouth 
is towards his own chest, so if is the best way of showing how 
far he is from thinking of hostility, 
February 28, 1881. 
The above account may be taken as fully trustworthy , 
Most of the observations recorded I have myself subse- 
quently verified numberless times. From the account, 
however, several observations which I happened to make 
myself in the first instance are designedly omitted, and 
these I shall therefore now supply, 
I bought at a toy- shop a very good imitation of a 
monkey, and brought it into the room with the real 
monkey, stroking and speaking to it as if it were alive. 
The monkey evidently mistook the figure for a real 
animal, manifesting intense curiosity, mixed with much 
alarm if I made the figure approach him. Even when I 
placed the figure upon a table, and left it standing motion- 
less, the monkey was afraid to approach it. From this it 
would appear that the animal trusted much more to his 
sense of sight than to that of smell in recognising one of 
his own kind. 
I placed a mirror upon the floor, and the monkey at 
once mistook his reflection in it for a real animal. At 
first he was a little afraid of it ; but in a short time he 
gained courage enough to approach and try to touch it. 
Finding he could not do so, he went round behind the 
mirror and then again before it a great number of times ; 
but he did not become angry, as the monkey of which 
Prof. Brown Robertson wrote me. Strange to say, he 
appeared to mistake the sex of the image, and began in 
the most indescribably ludicrous manner to pay to it the 
addresses of courtship. First placing his lips against the 
glass he rose to his full height on his hind legs, retired 
slowly, and while doing so turned his back to the mirror, 
looking over his shoulder at the image, and, with a pre- 
posterous amount of 6 pinch 5 in his back, strutted up and 
down before the glass with all the appearance of the most 
laughable foppery. This display was always gone through
