TL;DR: The methods used at present for the determination of the higher nucleic acids in organs are based on certain color reactions of their carbohydrate components, but if the quantitative estimations of desoxyribonucleic acid and of ribon nucleic acid could be based on phosphorus determinations rather than on color tests of their carbohydrates components, these difficulties might be avoided.

TL;DR: In this communication, a method is described which utilizes the reaction of acyl phosphates with hydroxylamine and the acyl part of the acid anhydride is converted into hydroxamic acid.

TL;DR: The extent to which metabolic balances of nitrogen, calcium, iron, etc., actually measure the day to day requirements in terms of net nutrients’ can be judged by comparing their total integration throughout growth with the composition of the mature body with respect to them.

TL;DR: Investigating quantitatively the effect upon arginase activity of a fairly large series of amino acids and of some amino acid derivatives has proved to be not only of practical, but also of considerable theoretical interest.

TL;DR: The Roughton-Scholander syringe is used both as the equilibration chamber and bubble analyzer, thus eliminating the necessity for transfer of the bubble, and the accuracy of the technique was evaluated by comparing arterial tensions with alveolar tensions.

TL;DR: The purpose of this investigation was to determine the electrophoretic constituents of plasma, under identical conditions in so far as possible, of a variety of easily accessible animal species in order to ascertain differences in composition.

TL;DR: An internal cycle exists for the second phosphate group, which is already present in the triose phosphate and after oxidation appears finally in the phosphopyruvic acid.
