Hey Doc, don't despair!!!
Pick up the shard of bone from the machine. Step back.
On your right, about 1centimetre past the bone machine is a microscope. Use the shard of bone on the microscope, fiddle with the control until Melanie says she can see flecks of Gold. Step back.
Go to the table which is now due East (if Mel stuck out her right hand) Check out the tools on the bench. Match main bone with sickle. Step back.
Click on magazines on right of your current position.
Hope this helps!!
