Since their composition during the middle to late twelfth century, Chretien's tales of Arthur and his chivalrous knights have fascinated generation upon generation of storytellers and their audiences, as well as literary critics and historians. Originally thought to have sprung from the newly civilized and thoroughly christianized courts of Marie of Champagne, daughter of Eleanor of Aquitaine, eighteenth century literary historians suggested that the legends behind the tales may have originated in the lost mythologies of Celtic Ireland and Wales. The following thesis examines the evolution of the theory of celtic origins of Chretien's Romans de la Table Ronde.

In Venezuela, four sheep fitted with rumen cannulas were fed the toxin-containing legumes <i>Leucaena leucocephala</i> (sun dried leaves and stems) and <i>Canavalia ensiformis</i> (grains). <i>L. leucocephala</i> did not have any apparent toxic effects on the animals, in spite of the presence of the toxic compounds 3,4 DHP and 2,3 DHP in the rumen. There were no significant effects on the rumen pH, concentrations of VFAs, microbial counts, rate of rice straw degradation or in the rumen outflow of liquids and solids. However, there was an increase in the concentration of ammonia in the rumen, and in the number of Gram negative rods isolated from the rumen of sheep when <i>L. leucocephala</i> was added to the diet. When <i>C. ensiformis</i> was supplemented the presence of canavanine in the rumen was confirmed. Sheep did not show signs of toxicity. There was no effect on rumen pH, microbial counts, degradation of rice straw or rates of outflow of liquids and solids from the rumen. There was a decrease in the rumen concentrations of valerate and ammonia and an increase in the numbers of Gram negative bacteria isolated from the rumen of sheep as the dietary inclusion of <i>Canavalia</i> increased. Several pure cultures capable of mimosine, 2,4 DHP and (in fewer cases) 3,4 DHP wre isolated. One of them, a Gram variable spore-forming rod, presumably a new species of <i>Clostridium</i>, was characterised. The presence of degraders of mimosine and DHP in the rumen presumably accounted for the lack of toxicity of <i>L. leucocephala</i> in Venezuela. The effect of canavanine on the growth and products of fermentation of pure cultures was independent of the Gram staining reaction and the results of experiments using media containing either peptides and amino acids or free amino acids alone suggest that canavanine may have an effect on peptide hydrolysis.

The high-mass X-ray binary SMC X-1 has been observed during the interval 1986-1989 at a threshold γ-ray energy of 0.4 TeV using the University of Durham Mark III air Cerenkov telescope at Narrabri. The Cerenkov arrival time series recorded during these observations have been tested for periodicity at the contemporary pulse period of the SMC X-1 X-ray pulsar. This period analysis was performed using a new technique - introduced in the present work - which is designed for TeV γ-ray source candidates in binary systems and which simultaneously seeks evidence for pulsed TeV γ-ray emission and information on the location of the emission site within the binary. Results are also presented from the period analysis of data accumulated at Narrabri during observations of the low-mass X-ray binaries X0021.8-7221 (in the globular cluster 47 Tucanae) and GX 1+4. X-ray binaries as a class of TeV γ-ray source are considered and their properties compared. Previous models which invoke the interaction of beams of high-energy particles with material within the environment of a binary system are discussed. One of these models is adapted in the present work in order to propose a simple explanation of the narrow TeV 7-ray orbital light curve observed for the high-mass binary Centaurus X-3. The new model accounts for the γ-ray emission from Cen X-3 in terms of the collisions of ultrarelativistic protons with an accretion wake trailing the X-ray pulsar. This model, which incorporates the steering of charged particles in the magnetosphere of the massive primary star, is also applied to the Vela X-1 binary in order to investigate claims that TeV γ-ray outbursts observed during X-ray eclipse arise at particle collisions with the limb of the supergiant companion.

Christian, Hitler's secretary from 1939-1942, 1943-1945, discusses the last days in the Fuehrer bunker

Colonel Bernd von Brauchitsch discusses the relationship between Hitler and Goering at the end of the war. He also discusses his father's, Field Marshal von Brauchitsch, disagreements with Hitler which caused him to resign in 1941.

Buchholz, a member of the stenographic service of Hitler's headquarters, describes briefings Hitler had with his staff where he discussed the handling of downed enemy airmen. File also contains Buchholz's Supplementary Statement on the Question of treatment of British commandos, June 30, 1954.

Nicolaus von Below, Colonel and Adjutant of the Luftwaffe, answers questions about the assassination attempt of Hitler on July 20, 1944, and details about people and events that happened at the bunker in Berlin in April 1945.

Hitler's dentist answers questions about how be met Hitler and became his dentist. He also gives a description of his escape from Berlin and his capture in May 1945. He tells of how he made drawings and a cast of Hitler's jaw from memory and gives a detailed account as to why he believes that his assistant's identification of Hitler's jaw was correct. The second day's interview is the dentist's detailed account of Hitler's bridgework.
