I wonder if members are aware of
this book, published in 1841:
Essai sur le Construction Navale des Peuples Extra-Europeenne by Francois-Edmond Paris.
Pre-dating Worcester by over a century it contains some wonderful illustrations of Chinese vessels (rather better than those in Worcester), such as the Salt Junk shown here.
I have a very large pdf of this book which I obtained last year while writing part 1 of the history. It's not in our library and perhaps should be. I have extracted the section on China as a smaller pdf if anyone is interested (all in French).
