Sorry it took so long for me to find the link; I had downloaded the presentation instead of bookmarking it.
This is not where I originally found the files; I had not seen this site before. They are the same files, though. Scroll down to the section on Barbados: Sugar and Slavery to choose the file(s) you want.
