Discusses the metallotherapy approach to viral infection, cadmium poisoning and Wilson's disease. Presents a plan for progress in metallotherapy through more education, more basic research, and more epidemiological studies. (GS)

Translates the recollections of Hermann Staudinger on the discovery of macromolecular structure. This is the second of a two part series. (DS)

This is the first of a two part series on Hermann Staudinger which describes the background of the discovery of chemical macromolecular structure. (DS)

Outlines factors to be considered in choosing suitable solvents for non-electrolytes and salts of weak acids and bases. Describes how, in some simple situation, the degree of solubility can be estimated. (Author/DF)

The chemist plays an important role in perfumery. There are scientific problems involved in relating odour to structure, including analysis of essential oils, quality control, and synthetic chemistry. (DF)

Describes the purpose and use of a card game which presents the essential groundwork of organic chemistry in a teaching aid form for use by the individual or by groups of sixth-form or first year university students. (Author/PR)

Describes the use of the game cards designed to help students master a large number of seemingly diverse yet fundamental reactions of classical organic chemistry. Claims that cards have stimulated students to learn organic reactions more willingly and more independently. (Author/PR)

A brief review is presented of some of the organic compounds and reactions that occur in soil. Included are nitrogenous compounds, compounds of phosphorus and sulfur, carbohydrates, phenolic compounds, and aliphatic acids. (BB)

Presented is a brief review of the chemistry of grasses. The significance of the main constituents of agriculturally important grasses is discussed in relation to ruminant nutrition. (BB)

Compare reactions in which the functional groups of title compounds are displaced. The overall order of activity observed for alkyl halides, alcohols, thiels, and aliphatic amines acting as bases or nucleophiles is reversed when reactions involve displacement of the functional group. (MLH)

A discussion concerning the choice of solvents for a chemical reaction is followed by an examination of the advantages of using liquid ammonia, oxide solvents, and molten salts as alternatives to water as a solvent. (DT)

Presents an account of the life of Otto Diels and explains his research on the constitution of cholesterol, the Diels-Alder reaction, and synthesis of cantharadin. (GS)
