EXPERIMENTS IN AIR MAKING.
Scientists have long been experimenting with the substances of which the air we breathe is composed, and much study has been placed upon the properties of the constituent parts. They have tried different combinations of these substances; but have been unable to find any combination which could be substituted for our atmosphere, without resulting in the death of the creature that breathed it. Professor Marcacci, of Palermo, Italy, has recently shown that an atmosphere artificially constructed with an equal amount of hydrogen substituted for the nitrogen can not support life for any length of time. He tried to keep animals in such an atmosphere, but he found that they soon died, the same effects being noticed as would result from cold. This is explained by the fact that hydrogen possesses greater conductivity for heat than does nitrogen. All of which shows that the Creator knew best when He prepared a home for men and beasts and an atmosphere for them to breathe.
