Here are the pdfs of my thesis. If you want to cite the ref is E. Vallance, State Oaths and Political Casuistry in England: 1640-1702, (unpublished University of Oxford D.Phil, 2000), this URL then access date.
Note that this is taken from an uncorrected copy in a cheap binding that I was able to pull apart and scan. The pagination is the same as the copy in the Bod and in the BL but there are one or two minor corrections which are missing in this version.
