Mr. Lowne thought they should not concern themselves about what " might 

 be," they had only to find out what was. If anyone thought that these bodies 

 were air sacs, let him prove it. 



Mr. Hailes said he had mentioned the matter because he understood it to be 

 stated that there was an analogy to the air bladder of the fish. 



Mr Lowne said many insects have air chambers; the cockchafer and stag 

 beetle have hundreds of them. 



Mr. T. C. White said he had been asked how these insects were dissected, and 

 he proposed to answer this by bringing up some cockroaches to the nest gossip 

 meeting, and giving a demonstration. 



Mr. Loy suggested that if Mr. White did this it would be well to bring 

 several of the insects and kill them in different ways— say one in methylated 

 spirit, another with ammonia fumes, and a third in boiling water — possibly it 

 miglit be found that during the slower processes the sacs would be emptied. 



The President remarked that they had had a most interesting discussion. With 

 reference to the Barbadoes earth, he wished to explain, in reply to questions, 

 that the portions marked " Chimborazo" were not from the South American 

 Volcanic district, but from an estate in Barbadoes bearing the same name.
