Hello Dale,
I must say I was please to see that you had scanned the first volume of Joshua's book. What a undertaking. I have both of these volumes, and the books are massive. I also have a few other books of his from the 1800's.
I have a great interest in all of this, as Joshua was my Great Uncle. Born in St Pancras England, and died in New York. He is from a family of engineers, and served his indenture under his father, at Ashford Works, in Kent England.
Thank you so much for scanning and preserving, his work.
