    No matter how many times the same original information is re-hashed, the
    fact that there is no _new_ original information prevents us from adding
    to the knowledge base.  There is still not a clear record of exactly
    which instrument was referred to and whether Newton's invention(s)
    played a role in Halley's voyages.
    As far as it being a "disclosure", there is little real information
    presented (that I've seen).  Certainly not enough to allow a patent
    reviewer to resolve priority.

    Hooke and Newton tangled a lot about a lot if things.  There's no
    guarantee (without going into the gory details, which aren't present
    here) that Hooke was annoyed about the priority over a double-reflecting
    instrument or whether he considered his single-reflecting instrument to
    be priority enough.  Sometimes those guys whinged about priority without
    worrying about what was actually at hand (Galileo, as an example of the
    kinds of attitudes among those old egos, claimed to have discovered
    everything in the heavens with his telescope and refused to accept
    anyone else's discovery as being unique - modern scientists tend to be a
    _little_ more discerning ;) ).

    Godfrey's is almost identical to the original of Hadley's, which in turn
    is little different from Newton's.  They ignore other instrument
    inventors, such as Caleb Smith and Jean-Paul Fouchy.
