portions of the interior lining of the bird’s stomach, and 
it was evident, from the short time that elapsed between 
the throwing up of the envelopes, that the bird in the 
interval had made a newjone and got rid of it also, with¬ 
out apparently being the worse.” However, as this pro¬ 
cess is daily continued for about two or three months, it is 
not to be wondered at, that whilst the female becomes so 
plump during her confinement as to be considered a bonne 
bouche by the natives of the country, the male becomes so 
lean and weak, that when a sudden storm, or fall of tem¬ 
perature happens, he not unfrequently dies, and the built-in 
family is left to perish of starvation. This curious habit of 
feeding his mate and young family seems to be innate in 
Hornbills, even in captivity, as Mr. Bartlett, Superintendent 
of the Zoological Gardens, London, records that “ The tame 
male Hornbill is particularly distinguished at all seasons by 
this habit of throwing up his food, which he not only offers 
to the female, but to the keepers and others who are known 
to him. The male Concave Hornbill (Buceros cavatus) 
now in the Gardens,” also exhibited here, “ will frequently 
throw up grapes, and, holding them in the point of the 
bill, thrust them into the mouth of the keeper, if he is not 
on the alert to prevent or avoid this distinguished mark 
of his kindness.” 
Continuing onwards, the visitor will find a large open 
space in the centre of the house, surrounded by cages, one 
containing a flying squirrel, Pteromys albiventer, described 
under the Rodent House, and others, having a variety of 
little birds, all living together in amity, but too numerous 
to be described in detail in this book. 
Instead of examining at present any of the com¬ 
partments to the south, the visitor should first proceed
