Treatment in health. 



Housing. — These animals have lived in excellent health in one 

 of the cages of the Gubbay House. 



In the ordinary course of management it may sometimes become 

 important to remove the inmates of one cage to another in the same 

 or in a different house. The essential point to remember is that it is 

 necessary to be careful, as the least interference with their accustomed 

 mode of life makes them suspicious, defeating, it may be, the very 

 object of a change. On one occasion, though the gentlest means were 

 adopted, the simple operation of a transfer frightened one of these animals 

 so much that it touched neither food nor water for the whole day. 

 Although these monkeys are by no means hardy animals, the excellent 

 health which those in the garden have enjoyed so long is mainly due 

 to the suitableness of their dwelling-house, where thej T can be protected 

 against all the risks of a changeable climate. 



Food. — Soaked gram, boiled rice, plantains, bread, biscuits, pump- 

 kins, sweet potatoes, dates, have been found to agree best with them. 

 'Ihey do not appear to have the same partiality for leaves as hanu- 

 mans have. JJoob grass and tender shoots of the tamarind and 

 pandanus leaves are, however, sometimes acceptable to them ; the same 

 quantity of food as has been recommended for a full-grown hoolock 

 is enough for one of these monkeys. 



Breeding. — These animals have never bred in this garden. 



Transport. — They can be transported in the same manner and 

 with the same precautions as a hanuman. 



Treatment in sickness. 

 These animals have uniformly maintained excellent health. With 

 the exception of a single occasion when the Phayre's monkey suffered 

 from an attack of diarrhoea, they have never been known to be unwell. 



Observations on their habits. 

 Both the Phayre's and the crested monkeys are very shy. They 

 generally avoid coming down from a retired place close to the top of 

 the cage. Though very quiet, they are not uninteresting. There is 

 a certain playfulness in their habits, but not so strongly developed 

 as in the case of other species. They are to a certain extent inquisi- 

 tive, but not at all mischievous. They agree very well with one 

 another. 



The following species (11 to 16) may be mentioned together. 

 (11) THE ASSAM LANGKUR.
