If you can decipher older terminology (or are willing to give it a try), there's interesting designs in it for knitting, crochet (including Tunisian crochet), tatting, needle lace, bobbin lace, embroidery, and lots of other stuff. It's hard to figure out what the needle sizes are, and I find the weights of yarns indecipherable. (I haven't bothered to do the research yet; I imagine there's a historical reproduction group on Ravelry that would be able to help me out.) It's an English book, and so the crochet terms are closer to the modern English crochet terms (i.e. English double crochet stitch = US single crochet stitch).
If you live in the US, you can see a complete scan of the dictionary from the University of Michigan library:
