not want it, having a good edition of it at present. When you have read
that, you will do well to follow it with Pere Bougeant's 'Histoire du
Traite de Munster,' in two volumes quarto; which contains many important
anecdotes concerning that famous treaty, that are not in Adamus Adami.

You tell me that your lectures upon the 'Jus Publicum' will be ended at
Easter; but then I hope that Monsieur Mascow will begin them again; for I
would not have you discontinue that study one day while you are at
Leipsig. I suppose that Monsieur Mascow will likewise give you lectures

that always accompanied with the maps of the places in question;
geography and history are very imperfect separately, and, to be useful,
