The cranium of a Tit is as large (relatively) and as well made as 

 ours, and he is simply one of the most active persons in Europe, 

 such as Falstaff would have been but for his redundancy of adipose 

 tissue. 



In the further development of the Tit's face the dentary and 

 palatal ends of the pras-inaxillaries become stunted, and so also 

 does the fore-end of the maxillary ; thus a hinge is formed between 

 these bones on each side, as in Finches, Parrots, and other strong- 

 cheeked birds.
