I still have my hands so overfull with work that I can only write you these few lines.
Document received. It is a worthy imitation of the Viennese model, which was later set aside by the Vienna cour de cassation. 
Enclosed one French and one English copy of the Resolutions.
Best greetings to Madame la Comtesse and Fränzchen.
