DE MONSTRIS. 267

 generally butterflies which are male on one side 

 and female on the other : the division being along the 

 centre of the body, exactly as is represented in the en- 

 graving of the Nurenberg Chronicle. 



Indeed, in actual nature are to be found almost

 part of the body which does duty for a head, and which 

 are in consequence called by the appropriate names of 

 Cyclops, Polyphemus, and so on. As to the many- 

 eyed men, they are entirely outdone by the insects, 

 some of which have more than thirty thousand eyes a 

 fact which infinitely exceeds the imagination of the old 

 writers or artists. The men with their faces in their 

 breasts are represented by the crabs, lobsters, shrimps, 

 and their kin, all of which have their mouths set 

 exactly in the situation in which the old artist has 

 placed the mouth of his headless man. 



Then the unipeds are far outdone by many of the 

 molluscs, whose structure may be characterised as a large
