206 SHORT NOTES 



it ; it still holds on to itself when any one comes near it, but walks 

 and climbs much better now when left to itself. It is in perfect 

 health. 



September 28th. — The Maias weighs 91bs ; it has been in 

 excellent health for a long time, suffering only from chronic nasal 

 catarrh, which makes it usually breathe through its mouth. It has 

 now cut three of its canine teeth, the right upper one alone remains 

 uncut. It climbs about readily, but still has the habit of clinging 

 to itself when picked up. 



Oct. 5th. — It accidentally strangled itself. It had been tied 

 up to keep it out of mischief, and it wound its chain tightly round 

 a bar in trjdng to get free. 



Its skeleton is now in the Sarawak Museum. 



The difference in the rate of developement of children and 

 of the young of the lower animals is mentioned by Darwin in his 

 "Descent of Man" and he says "the Orang is believed not to be 

 adult till the age of from ten till fifteen years." 



The average ages at which a child cuts its milk teeth are 

 usually given thus.

This rate of teething is taken from observations on European 

 children, whilst natives of tropical climates are supposed to de- 

 velope more quickly. On the other hand ill -fed town children 

 are apt to cut their teeth more slowly than those in more natural 

 conditions, and my Maias might have developed its teeth more 

 rapidly in the jungle under the care of its mother. 



The ages, too, at which the milk teeth are acquired need not 

 be proportional to the general rate of developement in Man and 

 in Maias.
