all distinction between these several classes has passed away.

We may, in short, say that the law of adoption runs through everything, and that it may be practised on every scale. What adoption is at the hands of the family, naturalization is at the hands of the State. And the same process extends itself from adopted or naturalized individuals to large classes of men, indeed to whole nations. When the process takes place on this scale, we may best call it assimilation. Thus Rome assimilated the continental nations of western Europe to that degree that, allowing for a few survivals here and there, not only Italy, but Gaul and Spain, became Roman. The people of those lands, admitted step by step to the Roman franchise, adopted the name and tongue of Romans. It must soon have been hard to distinguish the Roman colonist in Gaul or Spain from the native Gaul or Spaniard who had, as far as in him lay, put on the guise of a Roman. This process of assimilation has gone on everywhere and at all times. When two nations come in this way into close contact with one another, it depends on a crowd of circumstances which shall assimilate the other, or whether they shall remain distinct without assimilation either way. Sometimes the conquerors assimilate their subjects; sometimes they are assimilated by their subjects; sometimes conquerors and subjects remain distinct forever. When assimilation either way does take place, the direction which it takes in each particular case will depend, partly on their respective numbers, partly on their degrees of civilization. A small number of less civilized conquerors will easily be lost among a greater number of more civilized subjects, and that even though they give their name to the land and people which they conquer. The modern Frenchman represents, not the conquering Frank, but the conquered Gaul, or, as he called himself, the conquered Roman. The modern Bulgarian represents, not the Finnish conqueror, but the conquered Slave. The modern Russian represents, not the Scandinavian ruler, but the Slave who sent for the Scandinavian to rule over him. And so we might go on with endless other cases. The point is that the process of adoption, naturalization, assimilation, has gone on everywhere. No nation can boast of

absolute purity of blood, though no doubt some nations come much nearer to it than others. When I speak of purity of blood, I leave out of sight the darker questions which I have already raised with regard to the groups of mankind in days before recorded history. I assume great groups like Celtic, Teutonic, Slavonic, as having what we may call a real corporate existence, however we may hold that that corporate existence began. My present point is that no existing nation is, in the physiologist's sense of purity, purely Celtic, Teutonic, Slavonic, or anything else. All races have assimilated a greater or less amount of foreign elements. Taking this standard, one which comes more nearly within the range of our actual knowledge than the possibilities of unrecorded times, we may again say that, from the purely scientific or physiological point of view, not only is language no test of race, but that, at all events among the great nations of the world, there is no such thing as purity of race at all.

But, while we admit this truth, while we even insist upon it from the strictly scientific point of view, we must be allowed to look at it with different eyes from a more practical standing point. This is the standing point, whether of history which is the politics of the past, or of politics which are the history of the present. From this point of view, we may say unhesitatingly that there are such things as races and nations, and that to the grouping of those races and nations language is the best guide. We cannot undertake to define with any philosophical precision the exact distinction between race and race, between nation and nation. Nor can we undertake to define with the like precision in what way the distinctions between race and race, between nation and nation, began. But all analogy leads us to believe that tribes, nations, races, were all formed according to the original model of the family, the family which starts from the idea of the community of blood, but which allows artificial adoption to be its legal equivalent. In all cases of adoption, naturalization, assimilation, whether of individuals or of large classes of men, the adopted person or class is adopted into an existing community. Their adoption undoubtedly influences the community into which they are adopted. It at once destroys any claim on the part of that community to purity of

blood, and it influences the adopting community in many ways, physical and moral. A family, a tribe, or a nation, which has largely recruited itself by adopted members, cannot be the same as one which has never practised adoption at all, but all whose members come of the original stock. But the influence which the adopting community exercises upon its adopted members is far greater than any influence which they exercise upon it. It cannot change their blood; it cannot give them new natural forefathers; but it may do everything short of this; it may make them, in speech, in feeling, in thought, and in habit, genuine members of the community which has artificially made them its own. While there is not in any nation, in any race, any such thing as strict purity of blood, yet there is in each nation, in each race, a dominant element-or rather something more than an elementsomething which is the true essence of the race or nation, something which sets its standard and determines its character, something which draws to itself and assimilates to itself all other elements. It so works that all other elements are not coequal elements with itself, but mere infusions poured into an already existing body. Doubtless these infusions do in some measure influence the body which assimilates them; but the influence which they exercise is as nothing compared to the influence which they undergo. We may say that they modify the character of the body into which they are assimilated; they do not effect its personality. Thus, assuming the great groups of mankind as primary facts, the origin of which lies beyond our certain knowledge, we may speak of families and races, of the great Aryan family and of the races into which it parted, as groups which have a real, practical existence, as groups founded on the ruling primeval idea of kindred, even though in many cases the kindred may not be by natural descent, but only by law of adoption. The Celtic, Teutonic, Slavonic races of man are real living and abiding groups, the distinction between which we must accept among the primary facts of history. And they go on as living and abiding groups, even though we know that each of them has assimilated many adopted members, sometimes from other branches of the Aryan family, sometimes from races of men alien to the whole

Aryan stock. These races which, in a strictly physiological point of view, have no existence at all, have a real existence from the more practical point of view of history and politics. The Bulgarian calls to the Russian for help, and the Russian answers to his call for help, on the ground of their being alike members of the one Slavonic race. It may be that, if we could trace out the actual pedigree of this or that Bulgarian, of this or that Russian, we might either find that there was no real kindred between them, or we might find that there was a real kindred, but a kindred which must be traced up to another stock than that of the Slaves. In point of actual blood, instead of both being Slaves, it may be that one of them comes, it may be that both of them come of a stock which is not Slavonic or even Aryan. The Bulgarian may chance to be a Bulgarian in a truer sense than he thinks for; he may come of the blood of those original Finnish conquerors who gave the Bulgarian name to the Slaves among whom they were merged. And if this or that Bulgarian may chance to come of the stock of Finnish conquerors assimilated by their Slavonic subjects, this or that Russian may chance to come of the stock of Finnish subjects assimilated by their Slavonic conquerors. It may then so happen that the cry for help goes up, and is answered on a ground of kindred which in the eye of the physiologist has no existence. Or it may happen that the kindred is real in a way which neither the suppliant nor his helper thinks of. But in either case, for the practical purposes of human life, the plea is a good plea; the kindred on which it is founded is a real kindred. It is good by the law of adoption. It is good by the law the force of which we all admit whenever we count a man as an Englishman whose forefathers, two generations or twenty generations back, came to our shores as strangers. For all practical purposes, for all the purposes which guide men's actions, public or private, the Russian and the Bulgarian, kinsmen so long parted, perhaps in very truth no natural kinsmen at all, are members of the same race, bound together by the common sentiment of race. They belong to the same race, exactly as an Englishman whose forefathers came into Britain fourteen hundred years back, and an Englishman whose forefathers came only one or two hundred

years back, are like members of the same nation, bound together by a tie of common nationality.

And now, having ruled that races and nations, though largely formed by the workings of an artificial law, are still real and living things, groups in which the idea of kindred is the idea around which everything has grown, how are we to define our races and our nations? How are we to mark them off one from the other? Bearing in mind the cautions and qualifications which have been already given, bearing in mind large classes of exceptions which will presently be spoken of, I say unhesitatingly that for practical purposes there is one test, and one only, and that that test is language. It is hardly needful to show that races and nations cannot be defined by the merely political arrangements which group men under various governments. For some purposes of ordinary language, for some purposes of ordinary politics, we are tempted, sometimes driven, to take this standard. And in some parts of the world, in our own western Europe for instance, nations and governments do, in a rough way, fairly answer to one another. And, in any case, political divisions are not without their influence on the formation of national divisions, while national divisions ought to have the greatest influence on political divisions. That is to say, primâ facie a nation and government should coincide. I say only primâ facie; for this is assuredly no inflexible rule; there are often good reasons why it should be otherwise; only, whenever it is otherwise, there should be some good reason forthcoming. It might even be true that in no case did a government and a nation exactly coincide, and yet it would none the less be the rule that a government and a nation should coincide. That is to say, so far as a nation and a government coincide, we accept it as the natural state of things, and ask no question as to the cause. So far as they do not coincide, we mark the case as exceptional, by asking what is the cause. And by saying that a government and a nation should coincide we mean that, as far as possible, the boundaries of governments should be so laid out as to agree with the boundaries of nations. That is, we assume the nation as something already existing, something primary, to
