TL;DR: In making a preliminary study of Van Slyke’s method, it was attempted to cut down the period of digestion (2 hours on a water bath) by boiling the mixture gently over a micro burner until the solution was clear, and to diminish the possibility of occlusion of chloride or silver.

TL;DR: The method about to be presented depends upon the precipitation of the potassium chloroplatinate in the ash of physiological material and its subsequent determination by calorimetric or titrimetric procedure or by both.

TL;DR: In this article, the authors used the micro-technique described in previous communications to analyze 16 rat bone specimens and obtained a mean value of 1.99 ± 0.05 for the shafts; 2.10 for epiphyses and diaphyses; and 2.38 for the test lines.
