Abstract
MR. T. E. WALLIS, reader in pharmacognosy in the University of London, has been awarded the Hanbury Medal of the Pharmaceutical Society of Great Britain. Mr. Wallis has contributed thirty-seven papers describing original work to various scientific societies and their official organs. Roughly speaking, his work can be divided into six parts: (a) to discover those details of gross morphology and of microscopical structure by which it is possible to identify correctly vegetable materials used in medicine or as foods or spices either in the entire condition or in the form of powder; (b) to provide characters by which adulterants can be detected in foods and drugs, especially when in the powdered form or in broken pieces; (c) to discover general methods by which the proportions by weight of powdered material—drugs or foods—may be accurately determined by means of the microscope; (d) to devise improved optical apparatus and mechanical contrivances for use with the microscope in the study of food, drugs and powdered substances; (e) the production of books for the use of food analysts and the instruction of students of food and drugs; (f) to devise new methods for the determination of the purity of certain chemical substances used in medicine and pharmacy. Mr. Wallis's work has extended over tho past thirty-nine years, and its effect as a whole has been to make it much more possible to maintain an efficient control over tho purity and quality of food and drugs, especially when in the form of powder. The Hanbury Gold Medal is a memorial to Daniel Hanbury who died in 1875. It is awarded periodically for “high excellence in the prosecution and promotion of original research in the natural history and chemistry of drugs”. The Committee of Award comprises the presidents for the time being of the Chemical, Linnean and Pharmaceutical Societies, the chairman of the British Pharmaceutical Conference, and one pharmaceutical chemist.
