INTRODUCTORY 37 



management quite a large number of nests can be 

 got into a single glass-topped box. The encircling 

 paper also serves to keep the nests in their proper 

 shape. By this plan numbers of nests may be 

 arranged close together, which for a collector or 

 working naturalist is a matter of no small importance. 

 Of course the most elaborate method of preserving 

 nests is that adopted by the authorities at South 

 Kensington. Here the nests may be seen practically 

 in situ, but to display even a moderate number of 

 nest types on this principle would soon exhaust 

 even the space available at the Natural History 

 Museum.
