When I undertook the work of which these two volumes are the result, I scarcely realized the extent of the task before me. Now at the termination of my labours, which have extended over a period of nearly five years, I cannot give my work to the public without regret that it has not been accompanied by deeper study and more widespread research. But I have, in truth, been almost overwhelmed by the mass of materials at hand. These always increased enormously with every digression, and I found at length that I must be satisfied with what I had instead of seeking for more. Even with this restriction I have often been compelled to reject much, to epitomize and perhaps unduly abbreviate what I have used. A really copious and detailed history of Newgate would be a most voluminous affair. This well-known prison, which has stood for centuries upon the same site, is in itself an epitome of the criminal history of England; to have traced its chronicles down from epoch to epoch, closely and minutely, would have been wearisome to the reader. There is a family resemblance in crimes in all ages; when, therefore, the more prominent cases have been selected for description, a general impression will have been conveyed of the whole. I have followed this principle throughout, and have endeavoured to present a general, but not too detailed, picture of the various criminal periods through which Newgate has passed.
