The measures are such that the turbidity supervenes at once if the air in the bulb contains twenty thousandths of CO{2}.

The battery is kept up by adding every eight days a few thousandths of hydrochloric acid to a vatful of the spirits under treatment, say 5 kilos.

Imagine the incessant parental watchfulness of an authority which can testify concerning one two hundred and fifty thousandth of its charge that he is "a good soldier, willing and industrious, honest, sober, trustworthy and well-conducted."

If it becomes necessary to inject the contents of the bulb into the water twice, it is clear that the proportion is only ten thousandths; and if it requires ten injections the air contains ten times less CO{2} than that having twenty thousandths, or only two per cent.

The globular, or oval, corpuscles which float so thickly in the yeast as to make it muddy, though the largest are not more than one two-thousandth of an inch in diameter, and the smallest may measure less than one seven-thousandth of an inch, are living organisms.
