ON EXCHANGE. 
To the Editor of the * Intelligencer*' 
Sir,— The “ explanation ” offered in 
your last suggests to me some ideas re- 
specting the exchange of insects. There 
are two sorts of exchange to be noticed 
in the ‘ Intelligencer,’— the offer of com- 
mon insects in exchange for scarce ones.
