the highest temperatures do not show the 
greatest excesses for assaults, but the in- 
crease in the death rate is parallel with 
that of heat. During the unusually hot 
days in September and October we have 
about the same relation between the curves 
that was shown for the spring months—

which are themselves the effective ones— 
for instance, storms. 
The study of humidity, in its effect upon 
the data of conduct gave some interesting 
results, since it demonstrated, beyond a 
doubt, that conditions of low humidity are 
those most productive of misdemeanor.

i. €., a great excess in assaults and only a 
moderate one in deaths. These relations 
are fairly conclusive, as they are based upon 
36,000 assaults and 100,000 deaths. 
Generalizations based upon the study of 
the barometrical conditions show that 
nearly all the data studied were excessive 
during low readings of the instrument. 
There are many reasons for concluding, 
however, that the actual density of the 
atmosphere is not the influencing factor 
here, but the barometrical conditions as ac- 
companiments of other meteorological states

When we consider that the muggy, sticky 
days on which we feel it our natural pre- 
rogative to be ‘ out of sorts’ are of the op- 
posite character this is quite surprising. 
The deficiency of disorders on such days is, 
however, undoubtedly due to the fact that 
although they are emotionally depressing 
they are also physically weakening, and 
however ‘ugly’ a man might feel, if energy 
were lacking, to be offensively active the 
police court is none the wiser, and the fact 
is lost to our study. <A tabulation of pro-
