Thanks for that. That's what I figured 20 lines a page. If you look at the last column on the right hand page they are all signed by the minister James Bennett and below the last visible line you can see the top of the J, B, and two tt's on some pages, implying a further entry.
The last entry that I was interested in was William Swan who was baptised some years after he was born and I think (hope) there may be another sibling below him.
