To quickly assess the difficulty of the text, read a short excerpt:
The mole- cular refractions of the potassium, rubidium, caesium, and ammonium sulphates and selenates (the thallium salts are too difficultly soluble) were determined for the state of solution in water, in order to compare the values with those for the crystalline state. A very interesting result was obtained, which illustrates in a beautiful manner to what fine detail of the optical properties the law of pro- gression according to the atomic weight of the alkali metal, and the rule as to the p...osition of the ammonium salt near the rubidium salt, are carried. The following table 1 expresses the results : Comparison of the Refraction Equivalents for Crystalline and Dissolved States. Mean Molecular Molecular Salt. refraction of Refraction in Difference.
