One of the Lincoln-Douglas debates was held here in 1858.
He does not, however, appear to have taken part in the exclusion debates at this time.
Ministers may attend the debates of either house but can only vote in that of which they are members.
Gradually also he had the satisfaction of seeing the debates in the Speculative Society becoming famous enough to attract men with whom it was profitable for him to interchange opinions, among others Maurice and John Sterling..
All correspondence passed through his hands, he wrote all despatches, conducted the debates over which he presided, kept the minutes, drafted the resolutions, and was ex officio the leader and spokesman of the delegates who represented the Province of Holland in the States-General.
