[Reduced to a Point.&quot;] A man of the Marquis of 

 Worcester s ingenious cast of mind could readily have 

 made up the entire &quot;Century&quot; out of these systems of 

 alphabets and secret writing. He may have been 

 acquainted with &quot;Traict6 des Chiffres, ou Secretes 

 Manieres d escrire, par Blaise de Vigenere, Bourbon- 

 nois.&quot; 4to. Paris, 1586 now very scarce ; but indeed 

 there were many learned works on the subject, among 

 which Trithemius s &quot; Libri Polygraphia VI,&quot; 1600, 

 was conspicuous. The long disuse of such methods of 

 secretly conveying information, has reduced the cle 

 verest of these systems of Cryptographia in public 

 estimation. But, at the same time, these inventions 

 were quite consistent with the early times in which the 

 Marquis flourished. We shall see, in the next article, 

 what probably illustrates this proposed use of a mere 

 point or dot.
