To quickly assess the difficulty of the text, read a short excerpt:
The solution remained clear in both experiments. The results in general showed that precipi- tation of ferric hydroxide and basic ferric salts took place in solutions of other organic iron salts besides ferric ammonium citrate but that the time and manner of precipitation varied in different solutions. They also showed that manganese was not precipitated from solution in the same manner as iron, al- though microorganisms developed abundantly in solutions of organic manganese salts. It now becam...e necessary to determine whether the precipitation from these iron solu- tions was due to chemical action or to the ac- tivity of organisms. For this purpose another ftet of solutions was prepared in the same way as t^e stet just described except that iron al- buminate was omitted. After inoculation with ioiFihe cul turns were sterilized in an auto- clave. The stertlization produced a slight change of color in some of the solutions, and in the iron acetate solution it caused the forma- tion of a reddish-brown flocculent precipitate due to hydrolysis.
