AbstractFive glacial phases are recognized in the area described. Two of these are represented by the deposits of ice-sheets from the north-east and north-west respectively; the other three were of local origin. The materials composing the drifts differ sufficiently to enable the stratigraphy to be seen clearly. This shows that the local ice caps alternated with the invading ice sheets—which brings out a point of considerable climatological interest in that it is clear that the local ice advanced not simultaneously with the invading ice sheets but alternated with them. The order in which the five phases occurred is well established, but the importance of the intervals between the phases is at present uncertain.

The foregoing sketch brings out marked resemblances in the geological features of eastern and southern England on the one hand, and the neighbouring parts of the continent on the other. In both areas we find an old plateau of pre-Devonian rocks, against which Devonian and Carboniferous rocks are violently thrust from the south by Armorican and Variscan folds, giving rise to highly complex coal-basins in Belgium, France and Somerset, a type of structure possibly to be encountered in the future in Kent. In Belgium this plateau sinks to the north-east under the Campine coalfield, while in England its north-west margin is complicated by the incidence of posthumous folds of Charnian strike.In eastern England, east of the Charnwood line, there is evidence for the existence of Professor Kendall's Willoughby axis, with north-west strike; between this and the Charnwood line there are indications of similar parallel buried trend-lines in the folding and faulting of the visible Yorks-Derby-Notts coalfield, and also, as suggested by Professor Fearnsides, in the general shape of this basin.Further to the north, however, the general line of the Cleveland and Market Weighton axes is not Charnian, being about west 5° north. The Market Weighton axis, which is of Charnian type, with many repeated movements, does not form the boundary of the coalfield; this is in fact constituted by the southern flank of the broad Cleveland uplift, which is of Wealden type; an anticline superposed on an earlier sinking area.

From the modern town of Kos, on the site of the ancient capital at the north-east extremity of the island, to the village of Kephalos at the southwest end is a ride of eight hours.The village stands on a chalky plateau which beyond the isthmus marks the beginning of the mountain district of south-west Kos. This in turn is a repetition on a smaller scale of the mountain region, at the other end of the island, which forms the lofty termination to the long central tableland. The highest points of the mountain district are towards the south-east where the fall to the sea is very rapid. The highest neighbouring peak, Mount Ziní, is about an hour distant from the village in a south-easterly direction, while all that lies to the north-west of the main range is high pastoral country with many torrent beds.

The art in question is found on the structural slabs of a group of megalithic tombs in the valley of the Boyne in Ireland. The tombs are all passage-graves and are characteristically situated on the highest local ground and grouped in a ‘cemetery’. The Boyne cemetery is about 15 km from the east coast and about 50 km by road north of Dublin. In an area approximately 4 × 4 km are situated the three large tumuli of Newgrange, Knowth and Dowth, as well as over 40 other monuments, more than half of which are passage-graves (fig. 1).The three large mounds are only a few kilometres apart; in fact, from any one of them the other two can be seen since all are in commanding situations. They are similar as regards size and appearance, that is to say, each consists of a mound of stones, or stones, earth, etc., circular in plan and flat-topped, about 85 m in diameter at the base and 12 to 15 m in height. The base of each is surrounded by a continuous kerb of large slabs, 97 at Newgrange, an estimated 110 at Dowth, and an estimated 120 at Knowth. Newgrange is the central tumulus, Dowth is to the north-east, and Knowth to the north-west.

This study compared the utilisation of sparingly soluble P among soybean genotypes selected from 3 geographical regions with contrasting soil pH. Plants of 5 genotypes from each region were grown for 72 days in soil columns supplied with hydroxyapetite (Ca-P), AlPO4 (Al-P), or FePO4 (Fe-P) at a rate of 25 mg P/kg soil. NaH2PO4 (Na-P) was used as control at the same rate. Shoot weights ranged from 2.4 to 5.9 g/plant. On average, the genotypes selected from calcareous soils of north-west China produced the highest shoot biomass whereas those from neutral soils of the north-east region the least. Root biomass and root surface area followed the same trend. In contrast, the root-to-shoot weight ratio was highest in Fe-P and lowest in Na-P while root length in Na-P and Fe-P was greater than in the other P forms. The genotypes from the north-east region had higher P concentration in the shoot than those from the other 2 regions. Total P uptake ranged from 9.0 to 15.9 mg/plant for Na-P, and from 6.3 to 12.4 for the sparingly soluble P. Average total P uptake was the highest for the genotypes from the north-west region, and was greatest in Na-P and lowest in Fe-P. The genotypes from the north-east region displayed the greatest ability to use sparingly soluble P, and those from the north-west the least relative to Na-P. Total P uptake from the sparingly soluble P correlated highly with plant biomass production, N2 fixation and nodulation, and seed P, while the relative P uptake correlated highly with P concentration in shoots but neither correlated with root carboxylate release nor leachate pH. The results suggest that there is a substantial genotypic variation in utilisation of sparingly soluble P, which is related to early vigour, nodulation, and seed P reserve but not to origin site pH or root exudation.

A series of ca. 50 specimens of a small Longitarsus Latr. in the undescribed species were collected from the North-East of Asia Minor in the field research during the 21.VIII—1.IX.2003. Longitarsus ozbeki sp. n. is described and illustrated from north west of Turkey. This species is phenotypically similar to Longitarsus albineus (Foudras) and Longitarsus artvinus Gruev & Aslan. L. ozbeki sp. n. differs from the other two species by the outline of pronotum, coloration of body, punctuation of elytra, coloration of claws, tarsomeres, and metanotum, central lobe of anal sternite in male, aedeagus and spermathecae. Length ofbody is 1.9— 2.2 mm (mean 2.13 mm) and 2.4—2.6 mm (mean 2.46 mm) in male and female, respectively.

(2000). A new volcanic province: evidence from glacial erratics in western North Greenland. Geology of Greenland Survey Bulletin, 186, 35-41. https://doi.org/10.34194/ggub.v186.5213 _______________ Mapping and regional geological studies in northern Greenland were carried out during the project Kane Basin 1999 (see Dawes et al. 2000, this volume). During ore geological studies in Washington Land by one of us (B.T.), finds of erratics of banded iron formation (BIF) directed special attention to the till, glaciofluvial and fluvial sediments. This led to the discovery that in certain parts of Daugaard-Jensen Land and Washington Land volcanic rocks form a common component of the surficial deposits, with particularly colourful, red porphyries catching the eye. The presence of BIF is interesting but not altogether unexpected since BIF erratics have been reported from southern Hall Land just to the north-east (Kelly & Bennike 1992) and such rocks crop out in the Precambrian shield of North-West Greenland to the south (Fig. 1; Dawes 1991). On the other hand, the presence of volcanic erratics was unexpected and stimulated the work reported on here.

SUMMARY Downy mildew caused by the fungus Plasmopara halstedii is the main disease on sunflower in Bulgaria. In recent years a number of authors have reported the occurrence of new more virulent races of the pathogen. According to other authors these races demonstrate resistance to the fungicides used up to now. This fact is rather alarming and imposes the necessity of annual researches with the aim of following the changes in the downy mildew race variability. In the period 1995-1997 downy mildew isolates were collected from the following locations: Bourgas, Boyanovo, Karnobat, Ognyanovo, Selanovtsi, Kroushari, Lovech, Koubrat, Brashlyan, Sitovo, Tervel, Targovishte, IWS “Dobroudja” and Dobrich. The samples were assessed for virulence on a set of sunflower differential - lines under greenhouse conditions. The obtained results do not reveal a great race variability of downy mildew population in Bulgaria. In the period of study two races of the pathogen were identified: race 1 which infects the differential lines without genes for resistance to the pathogen. It is distributed in all sunflower production areas of the country. The other one is race 2. It is of limited distribution and has been registered in individual fields of north-east and north-west Bulgaria. It attacks the differential lines carrying the resistance gene Pl-1.

Early in 1963 much of the land occupied by the Roman building at Fishbourne was purchased by Mr. I. D. Margary, M.A., F.S.A., and was given to the Sussex Archaeological Trust. The Fishbourne Committee of the trust was set up to administer the future of the site. The third season's excavation, carried out at the desire of this committee, was again organized by the Chichester Civic Society.1 About fifty volunteers a day were employed from 24th July to 3rd September. Excavation concentrated upon three main areas; the orchard south of the east wing excavated in 1962, the west end of the north wing, and the west wing. In addition, trial trenches were dug at the north-east and north-west extremities of the building and in the area to the north of the north wing. The work of supervision was carried out by Miss F. Pierce, M.A., Mr. B. Morley, Mr. A. B. Norton, B.A., and Mr. J. P. Wild, B.A. Photography was organized by Mr. D. B. Baker and Mrs. F. A. Cunliffe took charge of the pottery and finds.

This granite forms an isolated mass, rising into two eminences a few miles south of Louisburg, called Corvock Brack (1287 feet) and Knockaskeheen (1288 feet). It is a greyish granite—generally fine—grained—consisting of quartz, two felspars,—one orthoclase, the other triclinic, probably oligoclase—and dark green mica. In some places there are patches in which the felspar assumes the appearance of “graphic granite.” Numerous boulders of this granite are strewn over the district to the north-west, and on the south side of Knockaskeheen; the rock is traversed by regular joints ranging N. 10 W., along which it splits off into nearly vertical walls. The position of the granite is shown on Griffith's Geological Map of Ireland, and it is surrounded by schistose beds, generally metamorphosed, and probably of Lower Silurian age. The granite itself is of older date than the Upper Llandovery beds, which lie to the southward.
