They possess a delicate Laticiferous layer of protoplasm, with numerous small nuclei lining Tissue the walls, while the interior of the tube (corresponding with the cell-vacuole) contains a fluid called latex, consisting of an emulsion of fine granules and drops of very various substances suspended in a watery medium in which various other substances (salts, sugars, rubber-producers, tannins, alkaloids and various enzymes) are dissolved.
In many of the granules, or more properly, clouds represented.
These end-organs are the active agents in taking up foreign granules, or bacteria, which may have found their way into the fluid of the body-cavity.
When spoken to the diaphragm vibrated, and thus set the carbon granules into vigorous vibration.
The chief difficulty with this transmitter, and with various others of later date based upon it, has been the frequent packing of the carbon granules, which renders the instrument inoperative.
