By 1886 the cases showing the beaks, feathers,

In 1887 it was noted that the collections of 

 zoology had increased in four years by 270,000

 the horns which it had shed every year of its life ; 

 it was presented by Mr. W. H. St. Quintin. In 

 the Bird series the anatomy of birds and the 

 leading characteristics of the Class ** Aves " were 

 begun. In their completed form they occupy one 

 bay of the hall, and are perhaps as good an example 

 as could be found of Flower's " selective " methods 

 of graphic exhibition. The problem was to give a
