Descripción

In this work, Pasteur Òdescribed a new and perfected method of preparing pure yeast [and] emphasized that yeast occasionally required small quantities of oxygen in order to retain its 'youth' and its capacity to germinate in oxygen-free environments. Having now achieved a new appreciation for the importance of oxygen in brewing, and especially the advantages of aerated wort, he insisted only that air should be carefully limited and freed of foreign germs rather than entirely eliminatedÓ (DSB). Octavo. viii, 387, [4, ads] pp. Twelve lithographic plates, woodcuts in text. Contemporary or slightly later quarter red calf over marbled boards, rubbed at extremities. A little light foxing. Inscribed on the half-title to PasteurÕs nephew, J. Vichot, with Òaffectionate remembrances, L. Pasteur.Ó This book has been cut down slightly for binding, and portions of several letters in the inscription are shaved. Otherwise very good. First edition of PasteurÕs groundbreaking book on fermentation. Though lacking the ads, which are an indication of state, this book has the scarce ads for PasteurÕs Etudes sur la maladie des vers a soie (1870) at the rear. Garrison and Morton 2485. Heirs of Hippocrates 1898. Norman 1658. Osler 1550. N° de ref. del artículo 12989
