XoTE. — In describing the properties of the organic phosphoric 

 acid of cottonseed meal, Technical Bulletin Xo. 25, the author 

 regrets that, through oversight, he omitted to mention that some 

 similar reactions had been reported by J. B. Eather, Bulletin 

 146, Texas Agricultural Experiment Station (1912), in his work 

 on " The Forms of Phosphorus in Cottonseed Meal." This ap- 

 plies particularly to the reactions which formerly had been con- 

 sidered indicative of the presence of p-\T0- and metaphosphoric 

 acids. In the above work 'Mr. Rather attributes these reactions 

 to the compounds which he had isolated rather than to pyro- and 

 metaphosphoric acids and states, p. 14, " It appears that, since the 

 compounds described on the preceding pages have properties very 

 similar to meta- and p^Tophosphoric acids, conclusions that the 

 latter are present in cottonseed meal have no value when based on 

 these reactions."
