Antoine Lavoisier performed his classic twelve-day experiment in 1779 which has become famous in history. First, Lavoisier heate

d pure mercury in a
swan-necked retort over a charcoal furnace for twelve days. A red oxide of mercury was formed on the surface of the mercury in the retort. When no
more red powder was formed, Lavoisier noticed that about one-fifth of the air had been used up and that the remaining gas did not support life or
burning. Lavoisier called this latter gas azote (Greek 'a' and 'zoe' - without life). He removed the red oxide of mercury carefully and heated it in a
similar retort. He obtained exactly the same volume of gas as disappeared in the last experiment
Lavoisier's experiments use the scientific, method of finding out the nature of an unknown substance by analysis, breaking down, and synthesis, and
then building it up again from its constituents. In his experiments Lavoisier separated air into two constituents: the one which supports life and
combustion, and is one-fifth by volume of air he called oxygen, the other four.fifths which is now called nitrogen. From the two gases he synthesized
something that has the characteristics of air. Lavoisier's experiments gave us the theory of combustion as we have it to this day: that when a substance
burns in air, it combines with oxygen of the air and the product of combustion is heavier than the original substance.

Thus, <em>the presence of the pelvic bone may indicate that whales had ancestors that walked on land</em>.
