In the years 1777–1778 four volumes were published under the title Legal Observations on Several Dark and Until Now Unverified Sections of the Introduction. The volumes were composed by a society of young legal practitioners from The Hague (Netherlands), the most famous among them being Joannes van der Linden. By then Grotius’s Introduction to the Jurisprudence of Holland was still the cornerstone of the law of Holland and around the year 1800 it would become the fundament for attempts to codify this law. Today the Legal Observations can function as entrance to the historical sources of the law of Holland as described by Grotius and developed further after publication of his Introduction.

关于法律意见的意见

在 1777 年至 1778 年间，以《关于几个黑暗且至今未证实的引言部分的法律观察》为标题出版了四卷。这些卷由来自海牙（荷兰）的年轻法律从业者组成，其中最著名的是 Joannes van der Linden。到那时，格劳秀斯的《荷兰法学导论》仍然是荷兰法的基石，在 1800 年左右，它将成为试图编纂该法的基础。今天，《法律观察》可以作为格劳秀斯所描述的荷兰法律历史渊源的入口，并在他的导言出版后得到进一步发展。
