Discovery of Nitrogen, by Caleb

Today in the Mystery of the Periodic Table, I read about how they separated  oxygen from the other gas, but what was the other gas? A mouse could not breathe in it. It tasted weird, and so they decided it was part of the recipe for the air we breathe, and that phlogiston was just a theory and that when a candle went out under a jar it was cause there was no oxygen, there was only nitrogen left which was the weird gas, and cause there was just nitrogen left that proved there was no phlogiston.
