Page 620 - A measured quantity of the solution is withdrawn and compared in a colorimeter with a standard solution of indirubin.
Page 741 - The absolute accuracy of the boiling points under diminished pressure must be examined in some future paper. The practical limit of temperature we can command by the evaporation of solid hydrogen is from 14° to 15° absolute. In passing it may be noted that the critical temperature of hydrogen being 30° to 32° absolute the melting point is about half the critical temperature.

The magnesia mixture shall be prepared as follows: — 110 grams of crystallised magnesium chloride and 140 grams of ammonium chloride shall be dissolved in 1,300 cubic centimetres of water.
Page 22 - ... was no trace of any unknown line. It appears, therefore, that helium contains no unknown gas, nor is it possible to separate it by diffusion into any two kinds of gas ; all that can be said is that most minerals which evolve helium on heating also evolve argon in small quantify.
Page 315 - ... per cent.) of choline or choline hydrochloride. The closely related, and much more toxic, base neurine is absent. In the case of choline, the fall of blood pressure is produced by vascular dilatation, especially in the intestinal area. Contrary to expectation, the spleen does not participate in this dilatation, but is constricted ; this constriction is followed by an increase of the normal splenic waves. It seems probable that the material in extracts of brain which Schafer and Moore (J.

Page 117 - It is therefore suggested that of the total quantity of uric acid normally excreted, that portion which bears a more immediate relation to food does not arise from nucleins but from some more soluble constituent of the diet acting either as a direct precursor or as a factor in a synthetic process.
Page 567 - Under the influence of a constant current the particles of proteid in a boiled solution of egg-white move with the negative stream if the reaction of the fluid is alkaline ; with the positive stream if the reaction is acid.
