which enter into their composition, and the different affinities which the particles ofthese elements exert upon each other, and the affinity which caloric possesses with them.The true constituent elements of vegetables are hydrogen, oxygen, and charcoal: Theseare common to all vegetables, and no vegetable can exist without them: Such othersubstances as exist in particular vegetables are only essential to the composition of thosein which they are found, and do not belong to vegetables in general.Of these elements, hydrogen and oxygen have a strong tendency to unite with caloric,and be converted into gas, whilst charcoal is a fixed element, having but little affinitywith caloric. On the other hand, oxygen, which, in the usual temperature, tends nearlyequally to unite with hydrogen and with charcoal, has a much stronger affinity withcharcoal when at the red heat, and then unites with it to form carbonic acid.Although we are far from being able to appreciate all these powers of affinity, or toexpress their proportional energy by numbers, we are certain, that, however variable theymay be when considered in relation to the quantity of caloric with which they are[Pg 121][Pg 122][Pg 123][Pg 124]

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
