Philosophic pursuits have likewise a noble and independent use of this kind ; and there is a double reason offered for pursuing them, for, whilst in their sublime speculations they reach to the heavens, in their application they belong to the earth ; whilst they exalt the intellect, they provide food for our common wants, and likewise minister to the noblest...

Page 53 - The atmosphere is principally composed, as our readers are aware, of two gases — oiygen and nitrogen mixed together in the proportion of 21 per cent, of the former, to 79 of the latter by volume. In other words, 21 gallons of oxygen, mixed with 79 of nitrogen, make 100 gallons of air; or 231bs. of oxygen, and 77 of nitrogen, make lOOlbi.
Page 76 - ... once flourished, they cannot again be expelled by all our endeavours : we think it very astonishing, while we really sow them ourselves every year. A famous botanist, attached to the Dutch embassy to China, could scarcely find a single plant on the corn-fields of the Chinese, except the corn itself.* The urine of horses contains less nitrogen and phosphates than that of man.
