 have no other instruments), one would suppose that 

 the acuteness of the pain would cause the person who

 be enabled to throw light upon it. It is to be hoped

 so violently shaken^ that the bottom of the inside of 

 the nest has appeared, and had there been nothing at 

 the rim to stop the eggs, they must inevitably have
