others being be ing Ina fire C earth th and water Up until 1757 little was known about air Then Dr Joseph flack Black who was experimenting with chemicals made the discovery of a gas he I called fixed air now known ai n carbon ide In 1775 Joseph Josrph Priestly Isolated oxygen n calling It air and thu for forthe forthe forthe the first time mankind began brgan to tt have some exact knowledge of atmosphere Lavoisier La a lending leading student of his period a afew afew afew few years later discovered ered carbon dioxide would extinguish flame lie He concluded therefore that an nn excess amount of carbon dioxide formed by breathing would contaminate indoor air Ills His standing and reputation brought ready acceptance acceptance accept accept- ance for this theory and It wee wre but a natural step to the premise that fresh air without excessive excessive ex ex- e carbon dioxide and with an abundance of oxygen was necessary for human well beIn be be- In ing A small number of scientists refused to concur concur con con- cur In Lavoisier's La theory but most scientists engineers and medical men held their tongues In the belief nothing was to be gained by the voicing of contrary opinions Among Amon the first public reports of these early theories is that of Dr It II It Sayers surgeon of ot the United States health service or n and chief i lct surgeon gO of f the e
