The condition and properties of the fluids at these two sources of supply, immediately before being submitted to the action of the lungs, will demand particular attention in the subsequent de- ductions. The chyle, says Richerand,* ** which is ne- cessarily affected by the various kinds of food which we use, has different appearances in the same persons, varying according to the quality of the different substances on which we feed; indigo gives it a blue colour, it is reddened by ** madder and beet root, and is changed green by ** the colouring matter of several vegetables.
