Can't Find specific P.S. in XML document

[saltar]

On the May 1849 document, there is a unindented P.S. that precedes "Fearing that this letter might possibly fall into the hands, of some of your clerks, & be opened by them, supposing it to be a business letter, I enclose it under cover of an envelope to J. Knox Walker Esqr., with a request that he will hand it to you."
However, I cannot find this section anywhere in the XML document.
