And this correspondence between the more general, powerful, and variable physical and social factors of <p 78>crime, as well as its more characteristic manifestations such as thefts, wounding, and indecent assaults, is so constant and so direct that, when I was studying the annual movement of criminality in France, and perceived some extraordinary oscillation in the crimes and offences, I foresaw that in the annals of the year I should find mention of an agricultural or political crisis, or an exceptional winter or summer in the records of the weather. So that with a single column of a table of criminal statistics I was able to reconstruct the historical condition of a country in its more salient features. In this way psychological experiment again confirmed the truth of the law of criminal saturation. Not only so, but it may be added that as, in chemistry, over and above the normal saturation we find that an increased temperature of the liquid envelopes an exceptional super-saturation, so in criminal sociology, in addition to the ordinary saturation we are sometimes aware of an excess of criminal saturation, due to the exceptional conditions of the social environment. Indeed it is to be observed not only that the main and typical criminality has a sort of reflex criminality depending upon it, but also that an increase of more serious or more frequent crimes induces a crop of resistance to and assaults upon the guardians of public order, together with false witness, insults, avoidance of supervision, absconding, and the like. Certain crimes and offences also have their complementary offences, which from being consequences become in their turn the causes of new offences. Thus concealment and <p 79>purchase of stolen goods increase simultaneously with theft; homicide and wounding lead to the illegal carrying of arms; adultery and abusive language to duels, and so forth.
