Fig. 11.—Hemometeb, (After Sahli.) hematin. This mixture La then diluted with water until it corresponds ex- actly in eolor to a tesl solution which is furnished with the apparatus, which also consists of hydrochlorate of hematin in a definite dilution. From the amount of water necessary to produce this correspondence in color, we may estimate the amount of hemoglobin in the drop of blood that has been tested. In its mechanism the apparatus is much superior to the original, as may be Been in the two illustrations which are placed side by side (Figs. 10 and I 1 ). Among otheT instruments (of which there is a greal number, cadi investi- gator having his favorite one) I should like to mention one of the Latest, the practical importance of which upon a large Bcale must -till be proven, and the use of which is Bomewhat more difficult than of those previously depicted : tIn- principle, however, is interesting, and differs greatly from thai of the colorime- tric ones that have been described ; for this reason it is necessary to compare Its results with those obtained by the aid of other instruments. I refer to the hemophotograph of GaertneT (see Pigs. L2 and L3). Gaertner started from the observation that the permeability of a diluted watery blood solution for the photographic rays of sunlighi was in inverse proportion to its hemoglobin con- tent. For this reason he spreads the blood solution fco 1"' examined in a layer of definite and uniform thickness, lays photographic paper under it. and per-.
