The Rev. T. E. R. Phillips submitted a proposal from Commission 16, suggesting that Commission 22 should take from them the subject of comets. After some discussion, in which it was pointed out that, on practical grounds, the methods of observation should outweigh any theoretical considerations in the matter, the following motion was moved by Prof. Öpik, seconded by Prof. Boothroyd, and carried:

“Commission 22 considers that it is not desirable that Comets should be joined to their subject.”
