§ II. Experiments on blood and urine taken in their normal state, and exposed to contact with air that has been deprived of the particles of dust which it generally holds in suspension 40

14. CHAPTER VI.

The object of all science is a continuous reduction of the number of unexplained phenomena. It is observed, for instance, that fleshy fruits are not liable to fermentation so lo...

15. CHAPTER VII.

The principles established in the course of this work implicitly involve the conditions of a new process of manufacture, the essential feature of which would consist in the prod...

12. CHAPTER V.

Amongst the productions that appear spontaneously, or, we should rather say, without direct impregnation, in organic liquids exposed to contact with the air, there is one that m...

11. CHAPTER IV.

Our observations in the preceding chapter will have shown that organic liquids, natural or artificial—the wort of beer amongst others—if exposed to contact with the air, rapidly...

10. CHAPTER III.

The new process of brewing, which it is the principal object of this work to explain, and which will follow as an immediate and inevitable deduction from the novel facts herein...

8. CHAPTER I.

Beer is a beverage which has been known from the earliest times. It may be described as an infusion of germinated barley and hops, which has been caused to ferment after having...

9. CHAPTER II.

From our preceding observations it will be evident that the manufacture of beer, the arrangement of breweries, and all the processes practised by the brewer immediately depend u...

13. Chapter III. § 6. The Dutch yeast was a “high” ferment.

On July 25th, 1873, we sowed a portion of this dried mixture in a flask of pure wort. From July 27th patches of bubbles from fermentation were visible on the surface.

§ I. Growth of _Penicillium glaucum_ and _Aspergillus glaucus_ in a state of purity.—Proofs that these fungoid growths do not become transformed into the alcoholic ferments of b...
