The ethnologist, who passes from the history of the varieties of the human species of the world at large, to the details of some special family, tribe, or nation, is in the position of the naturalist who rises from such a work as the Systema Naturæ, or the Règne Animal, to concentrate his attention on some special section or subsection of the sciences of Zoology and Botany. If having done this he should betake himself to some ponderous folio, bulkier than the one which he read last, but devoted to a subject so specific and[2] limited as to have scarcely found a place in the general history of organized beings, the comparison is all the closer. The subject, in its main characteristics, is the same in both cases; but the difference of the details is considerable. A topographical map on the scale of a chart of the world, a manipulation for the microscope as compared with the preparation of a wax model, are but types and illustrations of the contrast. A small field requires working after a fashion impossible for a wide farm; often with different implements, and often with different objects. A dissertation upon the Negroes of Africa, and a dissertation upon the Britons of the Welsh Principality, though both ethnological, have but few questions in common, at least in the present state of our knowledge; and out of a hundred pages devoted to each, scarcely ten would embody the same sort of facts. With the Negro, we should search amongst old travellers and modern missionaries for such exact statements as we might be fortunate enough to find respecting his geographical position, the texture of his hair, the shade of his skin, the peculiarities of his creed, the structure of his language; and well satisfied should we be if anything at once new and true fell in our way. But in the case of the Briton all this is already known to the inquirer, and can be conveyed in a few sentences to the reader. What[3] then remains? A fresh series of researches, which our very superiority of knowledge has developed; inquiries which, with an imperfectly known population, would be impossible. Who speculates to any extent upon such questions as the degrees of intermixture between the Moors and the true Negroes of Nubia? Who grapples with such a problem as the date of the occupation of New Guinea? Such and such-like points are avoided; simply because the data for working them are wanting. Yet with an area like the British Isles, they are both possible and pertinent. More than this. In such countries there must either be no ethnology at all, or it must be of the minute kind, since the primary and fundamental questions, which constitute nine-tenths of our inquiries elsewhere, are already answered.

Minute ethnology must be more or less speculative—the less the better. It must be so, however, to some extent, because it attempts new problems. Critical too it must be—the more the better. It often works with unfamiliar instruments, whose manipulation must be explained, and whose power tested. Again, although the field in which it works be wide, the tract in which it moves may be beaten. An outlying question may have been treated by many investigators, and the results may be extremely different. In British ethnology, the history of opinions only, if[4] given with the due amount of criticism, would fill more than one volume larger than the present.

The above has been written to shew that any work upon such a subject as the present must partake, to a great degree, of the nature of a disquisition: perhaps indeed, the term controversy would not be too strong. The undeniable and recognized results of previous investigators are truisms. That the Britons and Gaels are Kelts, and that the English are Germans is known wherever Welsh dissent, Irish poverty, or English misgovernment are the subjects of notice. What such Kelticism or Germanism may have to do with these same characteristics is neither so well ascertained, nor yet so easy to discover. On the contrary, there is much upon these points which may be well un-learnt. Kelts, perchance, may not be so very Keltic, or Germans so very German as is believed; for it may be that a very slight preponderance of the Keltic elements over the German, or of the German over the Keltic may have determined the use of the terms. Such a point as this is surely worth raising; yet it cannot be answered off-hand. At present, however, it is mentioned as a sample of minute ethnology, and as a warning of the disquisitional character which the forthcoming pages, in strict pursuance to the nature of the subject, must be expected to exhibit.[5]

The extent, then, to which the two stocks that occupy the British Isles are pure or mixed; the characteristics of each stock in its purest form; and the effects of intermixture where it has taken place, are some of our problems; and if they could each and all be satisfactorily answered, we should have a Natural History of our Civilization. But the answers are not satisfactory; at any rate they are not conclusive. Nevertheless, a partial solution can be obtained; a partial solution which is certainly worth some efforts on the part of both the reader and the writer. Other questions, too, curious rather than of practical value, constitute the department of minute ethnology; especially when the area under notice is an island. The date of its occupancy, although impossible as an absolute epoch, can still be brought within certain limits. Whether, however, such limits would not be too wide for any one but a geologist, is another question.

Now, if I have succeeded in shewing that criticism and disquisition must necessarily form a large part of such an ethnology as the one before us, I have given a reason for what may, perhaps, seem an apparent irregularity in the arrangement of the different parts of the subject. With the civil historian, the earliest events come first; for, in following causes to their consequences, he begins with the oldest. The ethnologist, on the[6] other hand, whenever—as is rarely the case—he can lay before the reader the whole process and all the steps of his investigations, reverses this method, and begins with the times in which he lives; so that by a long series of inferences from effect to cause, he concludes—so to say—at the beginning; inasmuch as it is his special business to argue backwards or upwards. Yet the facts of the present volume will follow neither of these arrangements exactly; though, of course, the order of them will be, in the main, chronological. They will be taken, in many cases, as they are wanted for the purposes of the argument; so that if a fact of the tenth century be necessary for the full understanding of one of the fifth, it will be taken out of its due order. Occasional transpositions of this kind are to be found in all works wherein the investigation of doubtful points preponderates over the illustration of admitted facts, or in all works where discussion outweighs exposition.

The period when the British Isles were occupied by Kelts only (or, at least, supposed to have been so) will form the subject of the earlier chapters. The facts will, of course, be given as I have been able to find them; but it may be not unnecessary to state beforehand the nature of the principal questions upon which they will bear.

The date of the first occupancy of the British Isles by man is one of them. It can (as already[7] stated) only be brought within certain wide—very wide—limits; and that hypothetically, or subject to the accuracy of several preliminary facts.

The division of mankind to which the earliest occupants belonged is the next; and it is closely connected with the first. If the Kelts were the earliest occupants of Britain, we can tell within a few thousand years when they arrived. But what if there were an occupation of Britain anterior to theirs?

The civilization of the earliest occupants is a question inextricably interwoven with the other two; since the rate at which it advanced—if it advanced at all—must depend upon the duration of the occupancy, and the extent to which it was the occupancy of one, or more than one, section of mankind. But foreign intercourse may have accelerated this rate, or a foreign civilization may have altogether replaced that of the indigenæ. The evidence of this is a fourth question.

So interwoven with each other are all these questions, that, although the facts of the first three chapters will be arranged with the special view to their elucidation, no statement of the results will be given until the invasion of the Anglo-Saxons, or the introduction of the great Germanic elements of the British nation, leads us from the field of early Keltic to that of early Teutonic research; and that will not be until the details of[8] the Britons as opposed to the Gaels, of the Gaels as opposed to the Britons, and of the Picts (as far as they can be made out) have been disposed of.
