"We thoroughly understand it now. The butterfly 

 and mosquito are closely allied to each other." 



" But, my dear Mr. W., am I to understand that the 

 cockroaches also are related to the butterflies ? Because 

 I see from this drawing and these dissected parts of a 

 cockroach that its body and limbs are formed on the 

 same model as those of a butterfly and a mosquito/' 

 The above question was asked by Vidyabhushan, whose 

 countenance wore an aspect of great seriousness 

 not unmixed with bewilderment. 



" You are right, my venerable friend. All these crea- 

 tures in which we find three distinct regions of the body, 

 as we have seen in a butterfly, with three pairs of legs 

 borne on the middle region, one pair of wire-like feelers,. 

 and two pairs of wings, belong to one class and are 

 known as Insects. If further we carefully look at each re- 

 gion of these insects, we shall find that they are made 

 up of a repetition of rings or segments." " What troubles 

 you, my lad ? Something appears to be weighing upon* 

 your mind. Speak out please. "'
