Abstract
THE object of this little book is stated to be to give directions for the chemical determinations of the ordinary constituents of urine and of the stomach contents that are of value for diagnosis. Even with this limitation, the directions given are too brief, especially as regards those for quantitative estimations. For the detection of albumen the heat test, and for sugar Trommer's test, alone are mentioned. For the quantitative estimation of sugar, it is stated that titration with Fehling's solution is only suitable for chemical laboratories, because the solution must be freshly prepared, and, “secondly, and this is much more annoying, it is extremely difficult to determine the end of the reaction, for solutions of the proper strength can be bought nowadays” (p. 38). The translation must have gone astray here. As regards practical value, the two pages upon the quantitative. estimation of sugar might have been omitted.
