 of a group of organic acids containing C, H, O, N.i 

 and a large proportion of P. The nucleinic bases are 

 present in the nucleinic acid radicles as organic com 1 

 pounds. The nucleinic acids occur in nature, free o 1 

 in combination with albumins, when they are calleO 

 primary acids. On decomposition they yield nucleini«l 

 bases, and according to their origin are termed sperm:) 

 nucleinic acid, thymonucleinic acid, yeast-nucleini j 

 acid, etc. According to Kossel, there are in realit | 

 only 4 true nucleinic acids, viz., adenylic acid, guan 

 ylic acid, sarcylic (hypoxanthylic) acid, and xantbyli 

 acid. On decomposition the primary acids give rise t 

 secondary acids which contain more phosphorus tha 

 the primary acids and may or may not give rise t 

 xanthin bases on further decomposition ; according t 

 Simon, they may be divided into acids of the type 

 plasminic acid and of thy minic acid respectively. A
