What is wanting to make up the hundred consists, doubtless, 

 of azote and oxygen. 



The copper salt contained, 



Carbon, . 48-94 

 Hydrogen, . 6-33 

 Chlorine, . 1-73 

 Oxide of copper, 3-48 



60-48 

 The ferruginous salt contained, 



Carbon, . 48-07 

 Hydrogen, . 6-21 

 Chlorine, . 1-76 

 Peroxide of iron, 2-37 



58-41 



These analyses would require repetition, and the quantity of 

 azote should be determined. 



Xantho-proteic Acid. This name has been given by Mulder 

 to a yellow coloured acid, obtained first by Fourcroy, by treat- 

 ing fibrin or albumen with nitric acid. During the action 

 azotic gas is evolved, while oxalic acid and ammonia are formed. 

 This acid was analyzed by Mulder, who found it composed of, 

 Carbon, . 51-32 or 34 atoms = 25-5 

 Hydrogen, . 6-575 or 26 atoms = 3-25 

 Azote, . . 14- or 4 atoms = 7-00 

 Oxygen, . 28-105 or 14 atoms 14-00 



100-000 49-75 



He considers it as a compound of, 



1 atom xantho-proteic acid, . C 34 H 24 Az 4 O 12 



2 atoms of water, . H 2 O 2 



C 34 H 26 Az 4 O 14
