ALTHOUGH the advantages of small-scale methods of analysis have led to provision in various British universities and technical colleges for a certain amount of instruction in micro-techniques, it is believed that refresher courses for chemists who have not had recent contact with micro-methods would be of value (see also Nature, 156, 588 ; 1945). Modern micro-methods are essential for attacking certain analytical problems, and in addition selected semi-micro and micro-methods offer advantages over more conventional methods in the teaching of practical chemistry to undergraduates. To provide practical experience in modern small-scale techniques, a summer school has been arranged at Queen's University, Belfast, during June 23-July 5. This course is planned to provide about seventy-five hours practical work. Particulars can be obtained from the secretary of the University.
