It's actually a journal article written in Isis.   Isis does have an online archive, so you can dig it up free of charge, but I believe you have to register to get it:

 John K. Wright, “Notes on the knowledge of latitudes and longitudes in the middle ages,”  Isis, Vol. 5, No. 1 (1923) pp. 75-98

I just copied his table out of that article.   The scatter plots were my first crude attempts to see if I could figure out what these places corresponded to.   I didn't get as far as actually putting onto a Mercator projection, however.   If you know of some software were one can input these points onto a Mercator projection, that would be nice, although I can probably cobble something together using Mathematica. 

Attached is an attempt to draw a map on a rectilinear grid (not a Mercator) and my guesses as to some of the place names - modernized.
