Commissioner of the Metropolitan Police.
I am offering you this old story of the beginnings of Finger-printing, by way of expressing my warm and continuous admiration of those masterly developments of its original applications, whereby, first in Bengal and the Transvaal, and then in England, you have fashioned a weapon of penetrating certainty for the sterner needs of Justice.
