In Desperate Need of Help (Dalton's Atomic Theory)

Okay, here's the problem:
For my freshman chem class we need to know which of Dalton's 4 atomic theories were disproven. There are two of them. I can't figure out which ones. Also, we need to know why they are wrong. I need this by tonight. Someone please help me! :bugeye:

Thank you so much!
Emily
