Dr Lidstone's paper was followed by a discussion.

The Faculty of Actuaries and the Institute of Actuaries had recently presented a gold medal to Dr Lidstone, and the secretary was instructed to convey the society's congratulations.

Great interest was also shown in Professor Turnbull's successful attempt to expand a scalar function f(X+A) of two matrices A, X as a Taylor series.

Professor Steggall thanked the Society for electing him to the chair (for a third time) in his last year as Professor at Dundee. He said that he would always remember his membership of the society with pleasure.

It was decided that the summer meeting of the society should be held at Dundee instead of St Andrews.

The meeting began at 6.15 pm and adjourned at 7.55 pm.
