future buildings, the Council are determined to keep in 

 view the principle of classification and concentration de- 

 veloped in last year's Report, convinced as they are that 

 the interest and utility of the Collection will be materially 

 enhanced by bringing together all those animals which are 

 actually allied to one another. For this purpose, and to 

 enable them to judge properly of the distribution of the 

 buildings, with a just view at once to economy and effect, 

 they have ordered a survey of the Gardens to be made to 

 a convenient scale.

 and the female is expected to calve about the middle of 

 June. 



The whole number of animals contained in the Mena- 

 gerie at the present moment is 894, of which 352 are

 species of Birds new to the Collection, have enriched the 

 Gardens during the past season.
