Among the aquatic productions ought also to he mentioned 

 calamochnos, in Latin known as " adarea," 19 a substance whicli 

 collects about small reeds, from a mixture of the foam of fresh

 hence it is that it is so useful as an ingredient in " acopu" 20

 with which they are affected ; an effect equally produced by 

 the ashes of any other kind of frog. If wood is rubbed with 

 the pulmo marinus, 26 it will have all the appearance of being
