On the first floor of the museum there is a "Royal Cabinet of Curiosities," which contains some very precious historical relics, besides a great number of different objects from China, Japan, and the Dutch colonies. Amongst other things there is the sword of that Ruyter who began life as a rope-maker at Vlissingen, and became the greatest admiral of Holland; Admiral Tromp's cuirass perforated by bullets; a chair from the prison of the venerated Barneveldt; a box containing a lock of hair from the head of that Van Speyk who in 1831, on the Schelde, blew up his vessel to preserve the honor of the Dutch flag. Here, too, is the complete suit of clothes worn by William the Silent when he was assassinated at Delft--the blood-stained shirt, the jacket made of buffalo skin pierced by bullets, the wide trousers, the large felt hat; and in the same glass case are also preserved the bullets and pistols of the assassin and the original copy of his death-warrant. This modest, almost rough dress, that was worn at the zenith of his power and glory by William, the head of the Republic of the Netherlands, is a noble testimony to the patriarchal simplicity of Dutch manners. There is perhaps no other modern nation, equally prosperous, that has been less given to vanity and pomp. It is related that when the Earl of Leicester, who was commissioned by Queen Elizabeth, arrived in Holland, and when Spinola came to sue for peace in the name of the King of Spain, their magnificence was considered almost infamous. It is further said that the Spanish ambassadors who came to the Hague in 1608 to negotiate the famous truce saw some deputies of the Dutch States seated in a field, meanly clad and breakfasting on a little bread and cheese which they had carried in their saddle-bags. The Grand Pensionary, John De Witt, the adversary of Louis XIV., kept only one servant. Admiral Ruyter lived at Amsterdam in the house of a poor man and swept out his own bedroom.
