It seems to me that the points of comparison between the United Kingdom and Victoria, in so far as they have any bearing upon crime, have now been exhausted; on almost every one of these points Victoria stands in a more favourable position than ourselves. The colony has, on the whole, a better kind of citizen; it has superior social and economic conditions; it has a far more effective system of police. On what possible ground, then, is it, except the ground of climate, that the Victorians are more addicted to homicide than the people of the United Kingdom? I admit it would be rash to assert that climate is the cause if our own and the Victorian statistics were the only documents to which we could appeal; it would be rash to draw such a sweeping conclusion from so isolated a basis. But when we know that the Victorian statistics are only one set of documents among many, and that all these sets of documents point to the operation of the same law, the case assumes an entirely different complexion. The results of the Victorian statistics harmonise with the conclusions already reached from a comparison of the criminal statistics of Europe and America. These conclusions in turn are powerfully reinforced by the experience of Australia. In fact, the whole body of evidence, from whatever quarter it is collected, points with remarkable unanimity to the conviction that, as far as European peoples and their offshoots are concerned, climate alone is no inconsiderable factor in determining the course of human conduct.
