to apply to him. My own language then ought to have made him 

 hesitate to do so. At the same time I must say, that had he not 

 denied the supposed imputation, I should have thought that such ex- 

 treme sensitiveness, like M. de Pourceaugnac's — " ce n'est pas moi, 

 je vous assure," — indicated some, internal uneasiness. His denial, 

 of course, entirely removes this suspicion. 



To any other entomologist who may chance to wince under my 

 remarks, I might be tempted to reply, " Voila un discours qui marque 

 quelque chose ; " but I have no intention to occupy more of your 

 space with this trivial matter, unless Dr. Erichson's missive, having 

 taken breath, finds strength to continue its journey. Should this 

 prove me to be in error, no one will be more happy or ready to con- 

 fess it than Your most obedient servant,
