They were designated by the titles of their office.
There was a Premier and a Home Secretary, and a First Lord of the Admiralty, and so on, and great was the pride of a Willoughbite when he first heard himself referred to as the Right Honourable! Everything that came before the house had to come in the form of a bill or a resolution.

Any one anxious to bring up a subject (and there was nothing to prevent the junior fag bringing in a bill if he liked) usually handed in his motion early in the session, so as to stand a good chance of getting a date for his discussion.

Later on, when more subjects were handed in than there were evenings to debate them, the order was decided by ballot, and due notice given every Friday of the business for the next evening.
Another feature of these meetings was, of course, the questions.

Any one was entitled to question the "Government" on matters affecting the school, and the putting and answering of these questions was usually the most entertaining part of an evening's business.

Naturally enough, it was not always easy to decide to whose department many of the questions asked belonged, but tradition had settled this to some extent.
