In Class 4, malicious oifcnccs against property—

Diff. = -00034 or — 7*94 per cent. 
In Class 5, forgery and other olTcnces against the currency—

It is therefore obvious that the tendency to crime at different ages is not the 
same in each class or form of crime, and that its relative intensity in various classes 
at given ages is also different. For while in the latter of the above terms oflifellffe 
i* an increasing tendency in class 1 of 20-95 per cent, above that of the precafiog 
term of life, in all the oilier closses there is a less tendency to crime at the wperwr 
time of life, varying from 3J>-01 per cent, in class 2 to 7*77 per cent, in clsaS. At 
other ages like uiflt-rcnces are to be found. 
_The honortance to crimina! jurisprudence of a solution of thb problem most be 
evident. No preventive measures can be safely adopted till the knowle^ edits rf 
the particolur tendencies to certain propensities and forms of crime at diflerent age; 
hut with this knowledge the chances of success in R\-erting crime must be greil«, »s 
the means are flirnislied of knowing in what particular sections of the peoplstbe 
strongest londency exists to Bpccific forms of crime. 
_ On reflection, weslinll now j?ei’ceive with still greater force than fortnerlytheneces- 
Mty whicJi exists for a very refined analysis being followed In investiwtions on enmt 
lit-rore drawing any conclusions. Tlie importance of determining theJ-atcoferinit 
at the different terms of life has already been shown, in order to determine the reli 
tire amount of crime in differeiic districts, as well a* to understand whether crime be 
on the increase or decrease. U also appears equally imjiortntit to determine tbejen* 
dcncy at the respective ages to the specinc forms of crime, otherwise the pertnrbstwns 
or which the various classes arc susceptible may vitiate conclusions based on snj 
cndencc rosling on mere general overages. 
^u-iug the years 183'l-fe,it was found that the tendency to crime was not ro grot 
at 20 years age and iipwartlg, as during the years 1842-44, but at tbeinfcritif^* 
crime was higher in the remote years than during the more recent period. TheWl*

It Is^ thus seen, that from 20 years of age and upwards there has been sn ^ 
^me in the period 1842-44 over that of 1834-30, varving at the diflerent sgei fw® 
to ,i5 per cent., and In tlie former paper it was shown that the lendencj w cf«w 
in the imcnncdiatc period of years 1840-41, was something like a mean 
e results given in the preceding abstract, and therefore poiadng to n gradual w- 
fnf***? *he criminal calendar of the country within these periods. One 
of particular attention, the fact that during ^ 
nf ’)** '“creased tendency to crime at ases 20 and up«'ard^, 
^9 there 1ms been a decrease of crime to the ext®" 
per cent, Tims is contrary to the popular opinion held on the subject.
