confinement at the place where they are giving trouble and the 

 resulting chrysalids should be sent : or, if there be any doubt about 

 the vital powers of the chrysalids, these should be kept until the 

 perfect insects emerge from them. Again, when the Entomologist 

 suggests a remedy against the ravages of any insect, the correspond- 

 ent should endeavour to return, for record, some account ot its 

 effects, whether they are successful or not.
