ANIMAL INTELLIGENCE. 
when at any subsequent time the mirror was placed unon 
the floor. 
From the first time that he saw me, this monkey took 
as violently passionate an attachment to me as that which 
he took to my mother. His mode of greeting, however, 
was different. When she entered the room after an 
absence, his welcome was of a quiet and contented cha- 
racter ; but when I came in, his demonstrations were posi- 
tively painful to witness. Standing erect on his hind legs 
at the full length of his tether, and extending both hands 
as far as he could reach, he screamed with all his strength, 
in a tone and with an intensity which he never adopted 
on any other occasion. So loud, indeed, were his rapidly 
and continuously reiterated screams, that it was impossible 
for any one to hold even a shouting conversation till I 
took the animal in my arms, when he became placid, with 
many signs of intense affection. Even the sound of my 
voice down two flights of stairs used to set him screaming 
in this manner, so that whenever I called at my mother’s 
house I had to keep silent while on the staircase, unless 
I intended first of all to pay a visit to the monkey. 
It has frequently been noticed that monkeys are very 
capricious in forming their attachments and aversions ; 
but I never knew before that this peculiarity could be so

while towards every one else, male or female, he was either 
passively indifferent or actively hostile. Yet no shadow .of 
a reason could be assigned for the difference. My sister, 
to whom animals are usually much more attached than 
they are to me, used always to be forbearingly kind to this 
one — taking all his bites, &c., with the utmost good 
humour. Moreover, she supplied him with all his food, 
and most of his playthings, so that she was really in every 
way his best friend. Yet his antipathy to her was only 
less remarkable than his passionate fondness of my mother 
and myself. 
Another trait in the psychology of this animal which 
is worth observing was his quietness of manner towards 
my mother. With me, and indeed with every one else, hi&
