54. In reference to the metamorphoses of uric acid 

 and of the products of the transformation of the bile, 

 it is not less significant, and worthy of remark, that the 

 addition of oxygen and the elements of water to the 

 elements of uric acid may yield either taurine and urea, 

 or taurine, carbonic acid, and ammonia.

55. Alloxan, plus a certain amount of water, is iden- 

 tical in the proportion of elements with taurine ; and, 

 finally, taurine contains the elements of superoxalate 

 of ammonia.
