 hooklets. By means of these hooklets it eventually 

 bored its way through the stomach of its first or inter-

 into one of the blood-vessels, and was carried to some

 In the meantime the cow was eaten up by another 

 vertebrate animal, say a tiger, and the tape-worm embryo 

 having reached the alimentary canal of its second or tiger 

 host developed itself into fully mature tape-worms as you 

 see them before you. 



" Ah, I see Vidyabhushan smiles. Do you understand 

 why ? In this short life history of a tape-worm he finds 

 additional argument in favour of his vegetarian 

 principle. Who knows if the animal we eat is not an

 perfect than the tape-worms and round-worms. Hari 

 Charan says some of them look like common earth- 

 worms and leeches. They cannot help doing so, I am 

 sorry to say, because they are as really earth-worn*s and
