The plant macrofossil contents of two fossil mammal middens were investigated. Midden MS was collected from near Mt Swan, 200 km north-east of Alice Springs in central Australia. The vegetation in this region is predominantly grassland scattered with low trees. Midden KS was collected from Kathleen Springs, 240 km west-south-west of Alice Springs. The flora in this locality is dominated by forbs and chenopods. Midden KS had a radiocarbon age of 1700 years BP at the top and 3500 years BP at the bottom. Most of the plant taxa in each midden were components in the flora of the vegetation zones currently surrounding that midden. However, the two middens, collected from different vegetation zones, shared only 33% of taxa. Similarly, only 24% of species were common to the July 1987 vegetation at the two localities. A vertical slice of midden KS was cut into 25 subsamples. No progressive change of subsample plant macrofossil assemblage with depth could be detected by Principal Components Analysis. However, there was a weak tendency for subsamples from the same level in the midden to be similar. It was concluded that mammal middens are potentially useful indicators of the vegetation history of central Australia.

Plant Macrofossil Analysis

We used the techniques of plant macrofossil analysis and radiocarbon dating to determine the minimum residence time of the endangered thread-leaved sundew (Drosera filiformis Raf.) in three bogs of southern Nova Scotia. The minimum residence times are 4240 cal. year BP for Swain's Road Bog, 2050 cal. year BP for Villagedale Bog, and very recent (modern radiocarbon age) for Port La Tour Bog, indicating that the species has likely been in the region for the past 4240 years. Analysis of nearby Old School Road Bog, which lacks D. filiformis today, failed to find any evidence that it formerly occurred there, suggesting that it may not have been more widespread in the past than it is today.Key words: Drosera filiformis, thread-leaved sundew, plant macrofossil analysis, radiocarbon dating, bogs, minimum residence time.

Black peat samples deposited in between sandy clay layers were collected from an uncovered profile at Rajarhat,24 Paraganas (N), 20 km extreme North East of the city of Kolkata, (22°34’N, 88°30′ E) West Bengal. The profile resulted from an excavation made during the construction of a multi story building. Palynological investigations of the peat samples revealed a large deposits of pollen grains of mangrove species such as Heritiera, Excoecaria, Rhizophora, Sonneratia, Avicennia, Bruguiera, Nypa Barringtonia, Phoenix paludosa, Aegicerasetc. Pollen grains of grasses, some freshwater plants, as well as fern spores (such as Acrostichum, Pteris, Pteridium and Polypodium) were also recovered in large quantities. All were found from a peat layer formed at a depth of about 5.35m to 6.14m from the surface. The fossil pollen assemblage found indicates the prevalence of a past typical mangrove vegetation, which is presently observed in the Sundarbans region (a mangrove swamps, about 85km south of greater Kolkata). The present study reflects a low lying landscape frequently transgressed by sea water and getting supply of fresh water from rivers. Ecological and edaphic factors such as increase of salinity, submergence, reclamation, flood etc. could have been responsible for any vegetation fluctuations.

Ras a1 Khaimah is the most northerly of the seven states comprising the United Arab Emirates and its Ruler, H. H. Sheikh Saqr bin Mohammad al-Qasimi, is keenly interested in the history of the state and its people. Survey carried out there jointly with Dr D. B. Doe in 1968 had focused attention on the site of JuIfar which lies just north of the present town of Ras a1 Khaimah (de Cardi, 1971, 230-2). Julfar was in existence in Abbasid times and its importance as an entrep6t during the sixteenth and seventeenth centuries-the Portuguese Period-is reflected by the quantity and variety of imported wares to be found among the ruins of the city. Most of the sites discovered during the survey dated from that period but a group of cairns near Ghalilah and some long gabled graves in the Shimal area to the north-east of the date-groves behind Ras a1 Khaimah (map, FIG. I) clearly represented a more distant past.

Insight Into

North- East India is an under veiled region with an awe-inspiring landscape, different groups of ethnic people, their culture and heritage. Contemporary writers from this region aspire towards a vision outside the tapered ethnic channel, and they represent a shared history. In their writings, the cultural memory is showcased, and the intensity of feeling overflows the labour of technique and craft. Mamang Dai presents a rare glimpse into the ecology, culture, life of the tribal people and history of the land of the dawn-lit mountains, Arunachal Pradesh, through her novel The Legends of Pensam. The word ‘Pensam’ in the title means ‘in-between’,  but it may also be interpreted as ‘the hidden spaces of the heart’. This is a small world where anything can happen. Being adherents of the animistic faith, the tribes here believe in co-existence with the natural world along with the presence of spirits in their forests and rivers. This paper attempts to draw an insight into the culture and gender of the Arunachalis with special reference to The Legends of Pensam by Mamang Dai.

BackgroundWhen women have a history of anorexia nervosa (AN), the advice given about becoming pregnant, and about the management of pregnancies, has usually been cautious. This study compared the pregnancy outcomes of women with and without a history of AN.MethodWomen with a confirmed diagnosis of AN who had presented to psychiatric services in North East Scotland from 1965 to 2007 were identified. Those women with a pregnancy recorded in the Aberdeen Maternal and Neonatal Databank (AMND) were each matched by age, parity and year of delivery of their first baby with five women with no history of AN. Maternal and foetal outcomes were compared between these two groups of women. Comparisons were also made between the mothers with a history of AN and all other women in the AMND.ResultsA total of 134 women with a history of AN delivered 230 babies and the 670 matched women delivered 1144 babies. Mothers with AN delivered lighter babies but this difference did not persist after adjusting for maternal body mass index (BMI) in early pregnancy. Standardized birthweight (SBW) scores suggested that the AN mothers were more likely to produce babies with intrauterine growth restriction (IUGR) [relative risk (RR) 1.54, 95% confidence interval (CI) 1.11–2.13]. AN mothers were more likely to experience antepartum haemorrhage (RR 1.70, 95% CI 1.09–2.65).ConclusionsMothers with a history of AN are at increased risk of adverse pregnancy outcomes. The magnitude of these risks is relatively small and should be appraised holistically by psychiatric and obstetric services.

Glossina Palpalis

As already stated in a report to the Advisory Committee for the Tropical Diseases Research Fund, dated May 9, 1910, I noticed early in February, 1910, while examining in class work a stained specimen of rat’s blood infected with what was supposed to be T. gambiense , a marked peculiarity in the morphology. This peculiarity was so striking that I doubted whether the trypanosome with which I was dealing was really T. gambiense . On making enquiries I was told that the strain was derived from a case of Sleeping Sickness then in Prof. Ross’s clinic in the Royal Southern Hospital, Liverpool. To make certain that there was no error in this statement I myself infected a rat from the patient’s blood. The same forms were, however, again encountered. After convincing myself that these forms were constantly present in infected rats, and that they were not shown by the rats infected with the old laboratory strain of T. gambiense maintained at the Runcorn Laboratory, I decided through pressure of work to ask Dr. Fantham (now working in the Liverpool School of Tropical Medicine, under funds allotted by the Advisory Committee for the Tropical Diseases Research Fund) to be so good as to assist me in the description of the morphology of this trypanosome. The following paper is the outcome of our joint work.—[J. W. W. Stephens.] History of the Strain . The trypanosomes used during this investigation were obtained from W. A., male, aged 26, a native of Northumberland, who was infected in North-East Rhodesia in September, 1909. It is necessary to set forth the itinerary of W. A. while in Africa, as he was never actually in an area infested with Glossina palpalis , so far as records are available, and indeed was never nearer (Kasama) than some 86 miles from such an area.

Rudston, a village in the East-Riding of Yorkshire, on the Wolds, near Burlington, is thus noticed in bishop Gibson's edition of Camden, col. 901. “More inward into the “land, is Ruston, where, in the church-yard, is a kind of “pyramidal stone of great height. Whether the name of the “town may not have some relation to it, can be known only “from the private history of the place; but if the stone bear “any resemblance to a cross, rod in Saxon doth imply so much.” This cross, as the bishop calls it, and I think not improperly, is a very curious monument; and, no doubt, of very remote antiquity. I am not aware that it has ever been engraved, and therefore I here present the Society with an accurate drawing* of it, which I received A. 1769, from the friendly hand of Mr. Willan, whose account I shall take the liberty to subjoin. “This stone stands about four yards from the North East “corner of Rudston church, which is situated on a high hill. “Its depth under ground equal to its height above, as appeared “from an experiment made by the late Sir William Strickland. “All the four sides are a little convex, and the whole covered “with moss. No tradition in this country of any authorrity, either concerning the time, manner, or occasion of its “erection.”
