I must not forget to take notice that about this time (1787 or 1788,) there appeared an invitation from a Baron or Prince S----, Governor of the Dutch fortress H----, before the troubles in Holland, to form a society _for the Protection of Princes_.--The plan is expressed in very enigmatical terms, but such as plainly shew it to be merely an odd title, to catch the public eye; for the Association is of the same seditious kind with all those already spoken of, viz. professing to enlighten the minds of men, and making them imagine that all their hardships proceed from superstition, which subjects them to useless and crafty priests; and from their own indolence and want of patriotism, which make them submit to the mal-administration of ministers. The Sovereign is supposed to be innocent, but to be a cypher, and every magistrate, who is not chosen by the people actually under him, is held to be a despot, and is to be bound hand and foot.--Many circumstances concur to prove that the projector of this insidious plan is the Prince Salms, who so assiduously fomented all the disturbances in the Dutch and Austrian Netherlands. He had, before this time, taken into his service Zwack, the Cato of the Illuminati. The project had gone some length when it was discovered and suppressed by the States. Zimmerman, who had been President of the Illuminati in Manheim, was also a most active person in propagating their doctrines in other countries. He was employed as a missionary, and erected some Lodges even in Rome--also at Neufchatel--and in Hungary. He was frequently seen in the latter place by a gentleman of my acquaintance, and preached up all the ostensible doctrines of Illuminatism in the most public manner, and made many proselytes. But when it was discovered that their real and fundamental doctrines were different from those which he professed in order to draw in proselytes, Zimmerman left the country in haste.--Some time after this he was arrested in Prussia for seditious harangues--but he escaped, and has not been heard of since.--When he was in Hungary he boasted of having erected above an hundred Lodges in different parts of Europe, some of which were in England. * * * * *
