« All the specimens of birds mentioned under 1—9, were obtained, in 

 an apparently good condition, from a dealer at the Sydney markets, on the 

 8th October. On the Island they were kept in spacious, airy boxes, so as to 

 be protected from any injurious effects of the weather. When they were 

 to be experimented upon (in case of feeding only), they were slightly 

 starved beforehand, and their boxes emptied of all except water. 

 During the course of the experiments they were regularly fed, as usual.
