Quinidine yields with chromic acid the same decomposition products as quinine.

Flowers in a state of vegetation are, I consider, more pernicious at night, or during the absence of the sun, than those plucked and put into water, provided they be not immersed too long a time; for immediately the stem is severed from the plant, the vital action, if it may be so termed, ceases, and decomposition commences; but till the decomposition has been going on some time, nothing of a pernicious nature need be apprehended.

In like manner, directly the vital principle becomes extinct in animals, decomposition ensues.

It is then gradually removed one shelf lower as the decomposition increases, until it arrives at the bottom shelf, where it is completely decomposed in the state of magnesia, which is emptied through, E.

Meat should not be kept until decomposition sets in, as by the putrefaction of the albuminous elements certain organic poisons are generated, and flesh partaken of in this condition is liable to result in serious illness.
