孔夫子旧书网 is selling "A Course of Lessons in Spoken Mandarin" ( 《华英联珠分类集成》) for 13000.00元.
I'm not sure who has that kind of dough to drop on a book, but it's certainly not me.
Some have used it to write papers:
文焕章《华英联珠分类集成》分析
传教士西南官话文献的罗马字拼音方案府
This is usually the sort of material that can be found on archive.org, but, alas, it isn't there.
Apparently it is in the Toronto Public Library and SOAS University of London.
Is there a digital version available that is somehow eluding me?
