The author has observed the suicide rate and homicide rate of the past 60 years (1900-'60) not only in Japan but also in many foreign countries from the standpoint of epidemiological statistics and has synthetically studies the relationship of specific qualities of its biological (sex, age), geographical (distribution) and time (yearly trend, seasonal variation) phenomena, with life-environment (chemicophysical, biological, social), and an epidemiological study clears it out that soil aggregation may be found both in suicide rate and in homicide rate. The outstanding features are as follows. 1) The geographical distribution of suicide rate has keen connection with the chemical constituents of river water. Where pH-value is in neutral or alkalic and Ca/K ratio is also large, and Na+K/Ca+Mg ratio is high, suicide rate is high. 2) The geographical distribution of homicide rate has keen connection with the chemical constituents of river water. Where pH-value is slightly acidic, and Ca/K ratio is also small, and Na+K/Ca+Mg ratio is high, homicide rate is high. 3) Therefore, geographical distribution of suicide rate and homiside rate is in reverse order fundamentally. 4) In short, how electrelytic balance with K and Ca as their central figure may be suposed greately to have relation with postnatal disposition that apt to go to suicide or formation of postnatal disposition that apt to go to homicide.
