It is important that speakers being introduced to the Society should be rehearsed in the home Department, both to ensure clarity of presentation and strict adherence to time limits. Suggested format is twenty minutes for the presentation and ten minutes for questions.
Care should be taken in the preparation of slides and overheads. A good rule of thumb is that text in slides (e.g.tables) should be prepared within a template 42 spaces in width by 14 single-spaced lines in height. The axes of graphs should always be labelled. As a courtesy to members of the society who are colour blind, figures should be prepared with discriminable black-and-white symbols and line-patterns, or without using red and green colours on the same graph. Photocopying of ordinary, typed material is most unlikely to be acceptable.
Data projectors for showing PowerPoint presentations will be provided at meetings.
