In effecting by these means the organization into globules of the soluble part of the yeast that we used in the second case, we find that a considerable quantity of sugar is decomposed. The following are the results of our experiment; 5 grammes of yeast caused the fermentation of 12.9 grammes of sugar in six days, at the end of which time it was exhausted.
When still more decomposed, they were found to be clay coloured by red ochre. As two of the lavas of the Giant's Causeway are parted by a bed of lignite, it is not improbable that the layers of laterite seen in the Antrim cliffs resulted from atmospheric decomposition.
Its mountains, from their impenetrable forests, dangerous breaks, and swampiness, are difficult of access, and its ridges are said to be more utterly irregular, its lavas more decomposed, and its natural sections more completely smothered under a profuse vegetation than those of any other island in the tropical Pacific.
The internal part of this granite subsists in a state of the most perfect solidity; the external again is evidently in a decaying state. This is a fact which we learn from the nature of feldspar, of which granite is in part composed; this crystallised substance is every where decomposed, where long exposed to the atmosphere.
Some combinations are very strong, cohering with great force, as metals; others are extremely feeble, their cohesion slight and easily decomposed, as in fugitive colours.
When the ray was made to pass through the two solutions successively, an orange-yellow color was obtained upon the screen, which color Lord Rayleigh asserted to be made up of red and green rays. To prove this, the ray of white light was decomposed by means of a prism, and the decomposed rays passed through the two solutions.
Thus the unit of quantity is the coulomb, the unit of current or quantity flowing per second is the ampere, the unit of electromotive force is the volt, and the unit of resistance is the ohm. The quantity of water or any other "electrolyte" decomposed by electricity is proportional to the strength of the current.
In the serum and antitoxin treatment, therefore, the allopathic school is imitating Nature's procedure in checking the growth of microorganisms, but with this difference: Nature does not suppress the growth and multiplication of disease germs until the morbid matter on which they subsist has been decomposed and consumed, and until the inflammatory processes have run their course through the five stages of inflammation; while serums and antitoxins given in powerful doses at the different stages of any disease may check and suppress germ activity and the processes of inflammation before the latter have run their natural course and before the morbid matter has been eliminated.
In this case but little yeast is formed, and a comparatively large quantity of sugar disappears sixty or eighty parts for one of yeast formed. Under these conditions fermentation is very sluggish. "If the experiment is made in contact with the air, and with a great surface of liquid, fermentation is rapid. For the same quantity of sugar decomposed much more yeast is formed.
Free oxygen imparts to the yeast a vital activity, but at the same time impairs its power as yeast qua yeast, inasmuch as under this condition it approaches the state in which it can carry on its vital processes after the manner of an ordinary fungus; the mode of life, that is, in which the ratio between the weight of sugar decomposed and the weight of the new cells produced will be the same as holds generally among organisms which are not ferments.
