Mr. M'Lachlan also exhibited two specimens of a species of Trichoptera — 

 Neuronia clathrata, Kol. — which occurred rarely in Burnt Wood, Stafford-

 the experiments he had been making. 



Mr. Francis Galton alluded to the close attention Mr. Merrifield had 

 given to the subject, and complimented him on the neatness, ingenuity, and 

 skill with which his experiments had been conducted, and on the results he 

 had obtained therefrom. Mr. Poulton, Dr. Sharp, Prof. Meldola, and others
