    In this thesis I propose to give, in chronological order, an account of the observations recorded in the literature of my subject, to illustrate them by means of drawings from sections of the spinal cords of amputated patients and others;and, finally, to discuss the facts reported and the various theories which they have been held to support.The drawings were made by me from sections which I prepared in the laboratory of Professor Marie in the Bicêtre Hospital at Paris. The drawings were produced by means of an apparatus which cast a magnified image of the section - stained by Weigert's method - upon the drawing sheet, so that its outlines could be readily and accurately reproduced. The reality of the scleroses demonstrated by the method of Weigert was confirmed by the subsequent staining of similar sections by the method of Van Giesen. To Professor Pierre Marie my thanks are due for his courtesy and kindness in supplying me with, the necessary material

    Daguenet le Fol: a lesser known representation of madness in the thirteenth century French Arthurian prose romances

    Whilst critical material on the subject of the heroes and other major figures in the Arthurian romances abounds, little attention has been paid to those who, although playing relatively minor roles in individual stories, pop up again and again across a wide range of such romances. The aim of this study is rehabilitate one such character who has received little critical attention, Daguenet le Fol, whose appearances in the French Arthurian prose romances are brief, but he is unique in that he owes his identity to his madness - his folie. Daguenet, for most modern readers, is a character who, due to the scarcity and brevity of his appearances, seems worthy of little more than a passing mention. However it is precisely the brief yet recurrent nature of his involvement with the romances which makes him so remarkable. Daguenet's increasingly detailed and significant appearances bear witness to the fact that despite his apparently minor status, his relationship to folie caught the imagination of a number of medieval writers. By bringing together his appearances in four thirteenth century French Arthurian prose romances, the prose Lancelot, prose Tristan, Guiron le Courtois, and the Prophécies de Merlin, and looking at them in the chronological order in which they were composed, this study traces the evolution of the portrayal of that folie as different authors manipulate the material produced by their predecessors for their own ends, developing and adapting various aspects of Daguenet's character yet retaining an overall sense of continuity of his identity. Thus this study demonstrates the dangers of neglecting a wealth of characters whose potential to enhance our understanding of this body of work and the way in which it was composed remains largely untapped
