Mr. CO. Waterhouse exhibited the upper and lower membranes of a wing of a 

 species of Attacus, which had been separated without removing the scales, and 

 mounted on glass so as to show the internal surfaces. He explained that he

 drawn asunder, and floated on water until the two membranes were entirely separated. 

 He said that some years ago Dr. Hagen had shown that this could be done with fresh 

 examples of Libellula. 



Dr. D. Sharp exhibited a photograph he had received from Prof. Exner, of
