He denied that gaseous atoms could have parts, although compound gases could.
The stomata serve for all gaseous interchange between the plant and the surrounding air.
Hence the gaseous atoms of hydrogen and oxygen could not have parts.
So long as they are connected together mechanically they have apparently the power of influencing one another in various ways, and of passing liquid or gaseous materials from one to another.
This law states that: - gases combine with one another in simple proportions by volume, and the volume of the product (if gaseous) has a simple ratio to the volumes of the original mixtures; in other words, the densities of gases are simply related to their combining weights.
