ItemThe role of symbols in the development of chemistry to 1916 : with, A dictionary of chemical terms (1600-1800)( 1966)The Oxford English Dictionary offers a number of meanings for the word symbol; "Something that stands for, represents, or denotes something else (not by exact resemblance, but by vague suggestion, or by some accidental or conventional relation).... a material object representing or taken to represent something immaterial or abstract ...... a written character or mark used to represent something: a letter, figure or sign conventionally standing for some object, process." When chemistry is taught today it is presented with its symbols developed and the rules of their combinations defined. However, in reaching this stage the chemist's symbols at various times have had the meanings listed above. Chemists and historians of chemistry have discussed the roles and origins of symbols only to a very limited extent. The aim if this thesis is to provide a chronological review of the use of chemical symbols beginning with the exoteric alchemical symbols and concluding with electron theory bonds. We shall show how this use varied from the time when empirical shorthand characters were employed to the time when formulae or combinations of symbols were used as structural diagrams of molecules written in conformity with rules provided by a theory of composition. This association of formulae and rules for their construction will be examined against the often uncertain and disputed nineteenth century background of atoms, radicals and valence. I shall include in this background two examples of mathematical interests in formulae, which have been almost completely ignored by historians of chemistry. They are Bridle's calculus and Sylvester's quantities.

ItemMerleau-Ponty and the body : some comments on the phenomenological approach to the person( 1962)In this thesis I intend to sketch out some of the most interesting concepts Merleau-Ponty uses which contribute to our understanding of the person. I will approach his notion of the person through his concept of the world, since it is always in the context of the world that I do in fact know myself and other people, and it is therefore in this situation that I must consider man if I am to understand him conceptually as well as existentially. This will lead to a consideration of the notion of the human body, as it is likewise always through the body that I meet other people, communicate with them and act In the world myself. Then I will try as best I can to assess Merleau-Ponty's contribution to and originality in his phenomenology of the person, and in doing so, I will raise a few questions which need further study.
