During his nine months confinement at the Hague he could do nothing in it; when removed to Louvestein he wanted several necessary pieces; since his happy escape he was much busied; besides it required time to range the several parts of his defence in proper order.

The work is divided into twenty Chapters: in the first he shews that each of the United Provinces is sovereign and independent of the States-General, whose authority is confined to the defence of the Provinces: in the second, that each Province is possessed of the Sovereignty in matters ecclesiastical, and that this sovereignty resides in the particular States of the Province: in the third and fourth, that the different opinions about Predestination ought to be tolerated: in the fifth, that the convocation of a Synod in the situation of affairs at that time must have been attended with great danger; that the assembling of the Synod of Dort was illegal, since it was done without consent of the Province of Holland: in the sixth, he sets forth the measures taken by the States of Holland to restore tranquillity; in the seventh, the reasonableness of the regulation of 1591 relating to the share which the Magistrates ought to have in the nomination of the Ministers of the Gospel; in the eighth, that the approbation of the majority ought to be looked upon as a decision: the excesses of the Contra-Remonstrants are particularised in the ninth: the tenth and eleventh justify the province of Holland in relation to the raising a new militia, which were called Attendants.
The informality of his arrest is displayed in the thirteenth Chapter; Grotius there shews that he and the others arrested at the same time had only executed the orders of their Superiors and Sovereigns; that those who arrested him had no power to do it; that the States-General had no authority over the subjects of the Provinces; that they were a party in the dispute; that the persons arrested were members of the States of Holland, and were arrested in the Province of Holland, where the States-General had no jurisdiction.

The fourteenth Chapter exposes the want of formality in the proceedings from the time of their arrest to the nomination of their judges.

The fifteenth Chapter points out the want of formality in the nomination of the judges: and proves the extravagancy of making it a crime in them to maintain the rights of the States their Sovereigns, agreeable to the express orders they received.
The sixteenth Chapter explains the informality committed after the Judges were nominated.

The seventeenth displays the irregularity of the sentence passed upon them.
