Dr. Dalefield's Toxicology Quiz October 2008

The toxicology quiz is up and running again!

All the contestants who get the highest score go into a draw for a skull-and-crossbones T-shirt, perfect for Halloween, Piracy on the High Seas, or just bad-taste dressing.  

Who can enter?

Anyone..

What to do if you don't know the answers?

Look 'em up, of course. There's a whole Web to explore...

What's the deadline?

The deadline for entries in this quiz is October 31, 2008.

What to do if you can't answer all the questions?

Enter anyway. You don't have to get all the questions right to be eligible for the prize...you just have to get a higher score than the other contestants.
