It is just so tempting to add all five volumes of
Gunther into the
Hooke article :-)

I don't know much about the publishing history of that work (or indeed the work itself
til about five minutes ago)
but you could be sitting on a small fortune there:

Also Gunther Sr died in 1940, so not long til public domain ... you'd better get
scanning :)
