became robust and strong. As a rule anthropoid apes 
have not thriven well in our Gardens. It is, therefore, a 
pleasure to be able to record the success which attended 
our efforts in connection with this particular specimen, 
more especially as he belonged to one of the most delicate 
and most interesting groups. At the time of his death he 
was undoubtedly the finest specimen of the kind in the 
United Kingdom, and probably also in Europe. 
“It is a matter of considerable difficulty to ascertain with 
any degree of exactitude the age of an anthropoid ape. 
Their development takes place more rapidly than in the 
case of man, and puberty is reached at an earlier period. 
Sinbad, when he first came to the Gardens, was reckoned 
to be two and a-half years old; at his death, therefore, he 
was probably about six. Still he was far from 
full-grown, and had clearly not reached puberty. The 
cranial crest, however, was beginning to show through the 
scalp, and he was not much under three feet in height. 
Four feet may be regarded as the average height attained 
by the adult male Orang, but cases are recorded in which 
certain individuals have reached five feet. 
“During the time that Sinbad resided in the Gardens his 
habits were closely observed by several Members of the 
Council, and it may not be out of place to introduce here 
certain facts in connection with these, which appear to be 
of especial interest. It is well known that most apes 
possess the power of expressing pleasurable sensations and 
emotions by an act akin to laughter. Sinbad had very 
special gifts in this direction. When tickled his lips were 
drawn backwards so as to partially expose the teeth, his 
eye brightened, and the skin around the orbital opening 
became slightly puckered. If the tickling were continued 
he gave vent to a sound which can be best described as a 
‘snigger.’ He was fond of fun, and in his heavy, pon- 
derous, sluggish way greatly enjoyed himself on Sunday 
afternoons, when his room was crowded by his admiring 
friends. In intellect he was not so quick as a Chimpanzee. 
For instance, he could not be taught the tricks which have 
covered with renown the female Chimpanzee ‘Sally,’ in 
the London Zoological Gardens. Still he was very saga- 
cious and observant, and not so much given to fits of 
temper and sullen moods. His keeper described him well 
when he said that in his behaviour ‘he was just like an 
idiot boy.’ 
“Tt is stated that the Orang never stands on its hind-legs, 
and, seeing that the perfectly upright walk of man is
