He passed on to the classification and habitat of different 
genera, nest-making habits, eggs, &c. Then to a brief 
account of the habits of the Emperors and Adelies, which 
was of course less novel ground for the old hands. 
Of special points of interest I recall his explanation of 
the desirability of embryonic study of the Emperor to 
throw further light on the development of the species in 
the loss of teeth, &c. ; and Ponting's contribution and 
observation of adult Adelies teaching their young to

birds lay themselves out to instruct their progeny.
