Hmm you should have if you press 'J' and 'Unknown' quest I think which is the crafting one, something about making 'x' and coming back to him, and he'll give you the other book.
Now since the patch though talk to any trainer in any crafting area and you should get it/progress it.
If you are unsure I believe you can start a newbie (same faction), get the quest, put the note in the shared bank, log in tribune, read it, get the quest and hey presto formagio you have the quest.
I believe though if you get the book you get the quest, I was in a similar situation with Gottaa although I had got the original note, when I went to the trainer in a new area (which you can now do since the patch) and he I think scrapped the quest I had and gave me a brand new one.
P.S Where on earth do you get 'liquid' from ? I could see it on the vendor and no logical idea what I would harvest to get liquid. I need to make a potion for the next step of my quest.
