NARVAEZ, Roberto. An encoded letter attributable to José Mariano Michelena (1824). Estud. hist. mod. contemp. Mex [online]. 2011, n.41, pp.119-133. ISSN 0185-2620.

This article offers a series of analysis and comparisons between archive documents and cryptological and historical documents to strengthen, particularly with the help of technical cryptoanalysis and reasoning by analogy, the probable conclusion that José Mariano Michelena was the author of a coded letter sent from England in October of 1824, as correctly believed by the compilers of the catalogue traditionally known as A calendar of the Juan E. Hernández y Dávalos manuscript collection (1954).
