Waller 10966. - FIRST EDITION of Pasteur's important study of fermentation. Pasteur discovered that contaminated beer was caused by microorganisms in the air and not spontaneously generated as previously believed. He perfected a method of preparing pure yeast, acknowledging that a small quantity of oxygen was important for brewing. Our copy has advertisements on rear cover running up to 1923, indicating a later issue, but includes the ad for Pasteur's "Études sur la maladie des vers a soie" (1870) on final 4 pages.
