It would appear that the son of the creator of Scoville’s Phonography *may* have been interested in other types of less savory shortcuts: google book link (The Shorthand Writer)
I say *may*, as I am not entirely sure the proprietor of Scoville’s Stenografy referred to in the article is actually the same Scoville that created Scoville’s Phonography. However, it does seem like a reasonable probability.
Wow, this is really interesting. More than likely he's the author.
I am not sure what this is all about? Who was Scofield? I only get a snippet view of this book (may be because of non-US).
archive.org has a couple of books on his system viewable:
Sorry, I'm a bit slow; it only just dawned on me you meant you couldn't see anything but the snippet view of the Shorthand Writer, not that you couldn't see full docs of Scoville's shorthand.
Have you tried going through a proxy? Sometimes that works for me when a link doesn't seem to like my origin.
