Each microfilm for the 1760's covers about 2 years - much is fairly standardised and most pages are not that dense - but there are interesting items (eg see http://www.isle-of-man.com/manxnotebook/parishes/rcath/p1759.htm for bit re Catholic priest in Peel, a list (very large!) on non-attendees at church for Andreas at http://www.isle-of-man.com/manxnotebook/parishes/as/1761p.htm, unpaid assessments for seats in Douglas Chapel http://www.isle-of-man.com/manxnotebook/towns/douglas/p1761.htm - all from one film I think, found whilst I was searching for something else.
