It's a 'head teachers' log book and it runs from 1850 ish for about 15 years. Fascinating to read about the early days of what would now be OFSTED and how the head master would write in it daily about the weather, (this features in every single daily entry), who'd turned up to school, lots about the harvest and how it affected attendance and who was misbehaving. Lots of info and a real insight into school life almost 170 years ago.
I can't make out lots of it as the writing is hard to decipher but happy to post some pics of some pages if anyone fancies having a go 
I found the book in a skip by the way. Some years ago. Put it in a cupboard and don't get it out too much
