No skulls or skeletons have been found associated with this culture, and there has been much speculation as to the race which was responsible for it. Owing to the presence of harpoons it was first assumed that this culture was a direct derivation from the Azilian and Magdalenian, though it has been pointed out that the Maglemose harpoons are very different in form from the Azilian, and resemble more nearly some found in eastern Russia.[70] Still the majority of authorities treat this culture as of Azilian origin. Others, relying largely on the resemblances of certain elements of culture to those found at some very late Aurignacian sites in South Poland, believe the people and the culture to have arrived from that region.[71] Recently I have suggested another explanation.[72] Noticing the resemblance between the Magiemose culture and a slightly later civilisation known as East Scandinavian or Arctic, which has been found at several sites associated with skulls of Mongoloid type, I have suggested that in the Maglemose people we may perhaps see the first arrival in Europe of that Mongoloid race, which now peoples a large part of the north-east of the continent. My suggestion has not been well received in Scandinavian circles, and M. Nordmann has submitted it to very searching though courteous criticism.[73] While duly appreciating the value of all the evidence he has cited, I am still of opinion that my view, though far from proved, meets the existing evidence as well as, if not better than, its rivals. The importance of the Maglemose problem for our purpose lies in the fact that certain sites in the British Isles have produced an industry which has been claimed, and perhaps rightly, to be akin to that of Mullerup and Sværdborg. Certain discoveries in the caves at Oban and on a raised beach on the island of Oronsay, are claimed to be of this or of Azilian culture,[74] while other finds at Holderness are said to resemble more closely still the Maglemose culture.[75] More recently still Mr. O. G. S. Crawford has suggested that certain implements, which he and I discovered last year at an early occupation site on the Newbury Sewage outfall works at Thatcham, Berks., bear close resemblances to some found at Sværdborg.[76] It is too soon yet to appraise the value of these resemblances. Some of these sites, notably those at Oronsay and Thatcham, appear on some grounds to be somewhat later than the settlements at Mullerup and Sværdborg. This does not, of course, disprove their cultural connection. It is unwise, at present, to draw any positive conclusions from such evidence, but we may note that it is possible that during late Azilian times, or perhaps later still, fresh elements entered the British Isles from the Baltic region, and that it is at least possible that these elements may have been of the Mongoloid race.
