Additional Information
Encrypted letter without date, 90 codegroups in sum total. The plaintext written separately on the lower part of the sheet of paper is likely to be the solution of the ciphertext above. Only a known plaintext attack can prove this. Van Swieten knew Count Cobenzl -the Governor of the Austrian Netherlands on behalf of Maria Theresia- well, because he lived in Brussels between 1755 and 1757. Yhius letter seems to be written later, during a trip or short stay in Germany
