Though the terrace gravels and palaeoliths of north-west Kent are well-known, there is little published on the stratigraphy of implements elsewhere in the county, except the Sturry deposits, two miles north-east of Canterbury (Archaeologia, LXXIV, 117). The geological Drift map is old (the latest edition issued in 1875), and there is no memoir to elucidate any but the Dartford area; but in 1925 the geology of the Canterbury district was described by Messrs. Dewey, Wooldridge, Cornes and Brown in the Proceedings of the Geologists' Association, vol. XXXVI, pp. 257–290, and Messrs. Wooldridge & Kirkaldy read a paper to that Association this April on the physiographic evolution of north-east Kent, which throws much light on the problem presented by the Fordwich flints.Formerly the port of Canterbury, Fordwich lies on the right or southern bank of the Great Stour opposite Sturry, and at the foot of a steep hill, which rises to 150 ft. and leads to an elevated plain between the valleys of the Great and Little Stour. In the angle between the road leading due southfrom Fordwich and that from Stodmarsh to Canterbury, west of Moat Cottages (6 in. O.S. map, Kent, XLVI, N.E.), gravel has been worked over a considerable area, the depth being about 7 feet on the east and over 20 feet at the west end. The nearest bench-mark is 151·4 feet and the base of the gravel on the west is therefore about 130 feet O.D., rising to the east. The tongue of high ground between the rivers is covered in patches with gravel and brick-earth resting on Thanet Sand, and forms a plateau about 5 miles long at about the 100 ft. level.
The glow discharge's main ionization breakdown processes have been understood for about one hundred years. The glow discharge, however, still remains as an avenue of fresh research in pattern formation and far from equilibrium systems. The primary and secondary ionization processes can be mathematically modeled as general branching processes. Not only is the Townsend breakdown criterion obtained but the ionization avalanche can be characterized as a branching set with a unique Hausdorff fractal dimension. These fractal dimensions show applicability using similarity principles and Paschen's Law.
Lake trout (Salvelinus namaycush) reared for 1 year at six levels of differential (excess) gas pressure (AP 4,17, 33,43, 58, and 75 mm Hg above equilibrium) were examined for incidences of eye abnormalities including nuclear cataracts, hemorrhages, corneal swelling, cloudiness, rupture, and loss of eyes. Frequencies of nuclear cataracts, eye hemorrhages, cloudy corneas, and bilateral anomalies were not directly related to increasing dissolved gas pressures. However, incidences of corneal swelling and of all abnormalities combined increased with gas supersaturation above AP 4.
One of the finest gravel-pits in the world for flint implements is in process of extinction, and a final opportunity has been given for studying its stratification with a view to classifying, however roughly, the thousands of specimens from this site that have passed into public and private collections both at home and abroad. Every collector is familiar with the name of Swanscombe, a village on the south bank of the Thames between Dartford and Gravesend, and many have procured implements from the workmen on the spot without realizing to the full the necessity of fixing the horizon of each, if their purchases are to be of scientific value.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
