COMPOUNDS PRODUCED BY DECOMPOSITION OF ORGANIC MATTER. The forms which organic substances assume when de- composed, are principally three. These forms are water, carbonic acid, and ammo- nia; and they are compounds of the four organic ele- ments, in various forms and proportions. How much does 100 cubic inches of hydrogen weigh? Of ni- trogen—atmosphere—oxygen—carbonic acid, and chlorine? What use does its peculiar lightness fit it for? How many forms do organic substances assume when decom- posed ? Of what elements are they composed ? *NoTB.—This table indicates the comparative weight of several com- mon substances. Fractions are omitted: 100 cubic inches of hydrogen weigh 2 grains, nitrogen " 30 " atmosphere " 31 " oxygen " 34 " carbonic acid" 47 " chlorine " 76 ".
