To ensure that there was always a speaker on hand, the colleges of Rotterdam, Leiden, Amsterdam, and North Holland took turns providing speakers for each assembly.
Selle eest, et igal kokkutulekul alati ka kõnepidajad kohal oleksid, hoolitsesid kordamööda Rotterdami, Leideni, Amsterdami ja Põhja - Hollandi kolleegiumid.
