 Hence this product is formed from morphia in accordance with the equation 

 4C 17 H 19 N0 3 + 1 4HI = 2H 2 O + 4I 2 + C 68 H 82 1 2 N 4 O 10 , 4HI. 



In physical properties and qualitative reactions the substance thus got 

 is indistinguishable from the product of the same composition obtained 

 from codeia ; like the codeia product, too, it loses the elements of HI on 

 long-continued boiling with water. 



§ 2. Action of Water on the foregoing Compounds. 



When the original substance C 68 H 82 1 2 N 4 O 10 , 4HI is boiled for five 

 hours with about three hundred times its weight of water, a liquid is ob- 

 tained from which white flakes separate on cooling ; these have the same 

 curious microscopical structure as the body similarly obtained from codeia,
