There are in the history of most countries, certain very remarkable eras, which deserve more particular inquiry and attention than the common run of history.  Such is the revolt of the Seventeen Provinces, in the reign of Philip the Second of Spain, which ended in forming the present republic of the Seven United Provinces, whose independency was first allowed by Spain at the treaty of Munster.  Such was the extraordinary revolution of Portugal, in the year 1640, in favor of the present House of Braganza.  Such is the famous revolution of Sweden, when Christian the Second of Denmark, who was also king of Sweden, was driven out by Gustavus Vasa.  And such also is that memorable era in Denmark, of 1660; when the states of that kingdom made a voluntary surrender of all their rights and liberties to the Crown, and changed that free state into the most absolute monarchy now in Europe.  The Acta Regis, upon that occasion, are worth your perusing.  These remarkable periods of modern history deserve your particular attention, and most of them have been treated singly by good historians, which are worth your reading.  The revolutions of Sweden, and of Portugal, are most admirably well written by L’Abbe de Vertot; they are short, and will not take twelve hours’ reading.  There is another book which very well deserves your looking into, but not worth your buying at present, because it is not portable; if you can borrow or hire it, you should; and that is, ‘L’ Histoire des Traits de Paix, in two volumes, folio, which make part of the ‘Corps Diplomatique’.  You will there find a short and clear history, and the substance of every treaty made in Europe, during the last century, from the treaty of Vervins.  Three parts in four of this book are not worth your reading, as they relate to treaties of very little importance; but if you select the most considerable ones, read them with attention, and take some notes, it will be of great use to you.  Attend chiefly to those in which the great powers of Europe are the parties; such as the treaty of the Pyrenees, between France and Spain; the treaties of Nimeguen and Ryswick; but, above all, the treaty of Munster should be most circumstantially and minutely known to you, as almost every treaty made since has some reference to it.  For this, Pere Bougeant is the best book you can read, as it takes in the thirty years’ war, which preceded that treaty.  The treaty itself, which is made a perpetual law of the empire, comes in the course of your lectures upon the ‘Jus Publicum Imperii’.

In order to furnish you with materials for a letter, and at the same time to inform both you and myself of what it is right that we should know, pray answer me the following questions: 

How many companies are there in the Saxon regiments of foot?  How many men in each company?

How many troops in the regiments of horse and dragoons; and how many men in each?

What number of commissioned and non-commissioned officers in a company of foot, or in a troop of horse or dragoons?  N. B. Noncommissioned officers are all those below ensigns and cornets.
