Note: "Although the donor of the BHL is suspicious that this odd script is a form of 19th-century shorthand (likely French), he acknowledges that this hypothesis remains unsupported by any evidence offered to date."
It's not enough that you say some name of the script, you have to actually read what's written there. That's the really hard part. My girlfriend can write one shorthand fast but she depended on her colleague to transcribe the texts so produced. Even when you know the idea it doesn't mean you can read it easily.
