Reading edition
The fluids were boiled at the low temperature, with the aid of an air-pump, merely in order to be able to procure a more perfect vacuum in the flasks; these experiments being destined to show whether the simple (uninoculated) solutions would become turbid in vacuo—that is to say, without the oxidizing influence of the air—when they had not been exposed to an amount of heat sufficient to destroy any living or dead ferments which they might contain.
