Great RARE antique hardback book from 1816 by Isaac Watts on "proof of a separate state of souls after death". Photos 2 & 3 show that there is also an antique pamphlet by Reverend Dr Achilli titled "The public proclamation of the pontifical government to destroy the Bible". Photo 10 shows that the front cover and first 20 preface pages have detached as a chunk between pages xx and xxi on "the life of Dr Watts" section.Photo 11 shows that another chunk of pages have almost detached between pages xxi and page 50. Other pages are bound strong. The cover looks like it once had a leather covering as you usually see this type of hardboard cover under leather. Other pages inside are bound strong and are in nice condition especially as the book is 207 years old!
