Synthetic Inorganic Chemistry is designed as "a course of laboratory and classroom study for first-year college students." It was first nublished in 1908.

The textbook also contains an extenaivc appendix which gives may be expected t o obtain in the laboratory, he feels, nevertheless, that somewhat more detail in explanation of the conduct much valuable information. Synthetic Inorganic Chemistry is a conservative book. The and purpose of the experiments is desirable. Thus, in the experiments concerned with the formation of osazones on page treatment of the theory of ionization (p. 82) is an example. The 62, some mention of the fact that the osazone derivatives of modern definitions of bases and acids are not given.

On page 74 a mold crystallize out in the boiling solution should stimulate the student solution is defined as follows: "A molal solution contains one mole of dissolved substance in 1 liter of solution, e.g., 40 grams t o more careful observation. An excellent feature of the baok is the inclusion, wherever of NaOH or 98 grams of HdO,." This is pretty generally given possible, of quantitative material rather than the older type of as the definition of a molar solution, while a molal solution is defined as one containing 1 mole in 1400 grams of water.

I t is now considered likely that nuclei are built of and enthusiastically carry out even the simpler experiments with a quantitative background. Biological chemistry has beeu slow protons and neutrons.
