I am in the King's bedroom and need to use the green bottle on the footman. The trouble is I don't have a green bottle in inventory. What can I do if anything?

You need to make a knock out drug (that's what turns the bottle green) You need to find the alchemist.

Thank you very much. Now I'm stuck trying to get the sculpure guy <img border="0" alt="" title="" src="graemlins/woozy.gif" /> to make me the mold of Pazuzu. I have given him the portrait of Christophe Gabriel Allegrain, but I can't get him to take the picture of Pazuzu. What am I doing wrong or what did I do or not do? <img border="0" alt="" title="" src="graemlins/woozy.gif" />

Going by the wt here so bear with me:

Did you go back to the Apollo room and talk to Mr. Duplessis? There needs to be a chisel and mallet drawn on the picture before the sculptor will take it. The wt says to use the portrait on the canvas.
