Briefly noted: N (3)

More than one of these 7 encyclopedias carries each of the following subjects — but every one of them treats it in a sentence or two and then moves on. They are gathered here so the different accounts can sit side by side.

Numismatics

Collier's New Encyclopedia: the science and study of the coins of all nations. In the wider though less accurate, acceptation of the term it includes also that of medals, both artistic and historical. The various branches of numismatics are (1) Greek, Phœnician, etc.; (2) Roman and Byzantine; (3) Mediæval and Modern; and (4) Oriental. The chief value of numismatics consists in the light which coins throw on history.

In vegetable physiology, it consists of seven processes: absorption, circulation, respiration, transpiration, excretion, assimilation, and growth. The nutrient substances-some of them essential and all of them useful-are , oxygen, nitrogen, hydrogen, sulcarbon phur, iron, calcium, potassium, magnesium, phosphorus, sodium and chlorine.
