He was pleased that his brother-in-law, Count Schwartzburg, had been selected as the Emperor's agent in the affair, but expressed his doubts whether much good would come of the proposed negotiations.

Remembering the many traps which in times past had been set by Philip and his father, he feared that the present transaction might likewise prove a snare.

"We have not forgotten the words I 'ewig' and 'einig' in the treaty with Landgrave Philip," he wrote; "at the same time we beg to assure his Imperial Majesty that we desire nothing more than a good peace, tending to the glory of God, the service of the King of Spain, and the prosperity of his subjects." This was his language to his brother, in a letter which was meant to be shown to the Emperor.

In another, written on the same day, he explained himself with more clearness, and stated his distrust with more energy.
There were no papists left, except a few ecclesiastics, he said; so much had the number of the Reformers been augmented, through the singular grace of God.

It was out of the question to suppose, therefore, that a measure, dooming all who were not Catholics to exile, could be entertained.
