    course northwards, during which, it would receive the Ouse, where similar remains have been found. It was probably on the eastern side that these early immigrants found the easiest access to the interior of the country. First there was the broad valley of the Thames to the south, then in succes- sion towards the north they found the vast plain from which ramified towards the west and north-west the valleys of the Ouse, the Nen, the Welland, the Witham, and the Glen, now covered by the sea and known as The Wash. Still further north were the valley-inlets of the Humber, the Tees, and Tyne; all to be remembered in connection with the first advent of man and his fellow mammals to this land, and with their important relation now to their descendants' health and diseases. So much for the North Sea. In the English Channel mammalian remains have been dredged up in the same manner as in the North Sea. This Professor James Geikie asserts in his Great Ice Age, and, moreover, tells us that peat has been dredged up in this channel, and that sunken forests abound along the coasts of Brittany, Normandy, and the Channel Islands, where trees have been observed at a depth which could not be less than sixty fathoms below high-water mark (p. 309). The valley which is now covered by the waters of the English Channel differed widely from that of the North Sea. On its English side there is not a fully formed river flowing into it; and the majority of the rivers that do fall into this channel have their courses at right angles to the south-west or nearly so. There were no broad river valleys opening into what may be termed the great ancient Seine Valley, of which the Somme is a tributary, as into that of the North Sea, which might be called the great ancient Thames Valley. The river Seiue is the only fully formed river that falls into the English Channel on its south side. These facts must be borne in mind when studying the distribution of disease along the coasts of the southern and eastern counties and districts of England.
