Mr. Thomas King exhibited specimens of Cerastium arvense,

 development known as "phyllody." 



The Chairman (Mr. Turner) showed a specimen of Symphytum

 nectar in the usual way. 



Mr. Robert Broom exhibited a very lively specimen of the 

 Green Tree-Frog, Hyla arborea, L., from the North of France ;

 as the cutting of timber in British Guiana has been restricted 

 on account of its influence on the rainfall. 



Mr. Thomas King made some remarks on the formation of 

 the fruit in the Conifervc, ; also on recently observed facts 

 regarding the fructification of Ferns, which show that the

 King's remarks were illustrated by means of diagrams and 

 specimens.
