Reviving a possibly ancient thread here. Just to put an end to some of the rather extravagant speculation, both the original shorthand snippets and the subsequent additional full-page post are almost certainly in one of the (many!) variants of one of Shelton's systems (Pepys and Isaac Newton were both users of Shelton's system. They were hugely popular at the time, and were used widely). Church officials were a significant market, because of the importance of the verbatim reporting of sermons. Subterfuge and shennanigens are, sadly, not a necessary corollary of shorthand usage.
That said, Shelton's systems (and others of the time), although well documented, take a bit of getting into, and I am a bit rusty. The problem is the vast number of so-called `arbitraries', signs which don't follow the rules, and which have to be looked up in any number of badly written, badly printed pamphlets and tutorials, many of which are still not available in electronic form. Shorthand writers of the time also seemed to relish the challenge of writing in the tiniest hand they could (Pepys being a signal offender). The full-page contribution to this thread is, however, a model of clarity (as far as such is possible!).
I'm hunting around for the correct versions of Shelton for these two conundra (they are probably not the same), and will post transcriptions when (if) I do.
