large part of that which flows through the thoracic duct. The gall-bladder and bile ducts have rich subepithelial plexuses and the former a subserous plexus.
  The spleen has a rich subserous set and a capsular set of lymphatic capillaries. Their presence in the parenchyma is uncertain.

  The nasal cavity has extensive capillary plexuses in the mucosa and submucosa.
  The trachea and bronchi have plexuses in the mucosa and submucosa but the smaller bronchi have only a single layer. The capillaries do not extend to the air-cells. The plexuses around the smaller bronchi connect with the rich subserous plexus of the lungs in places where the veins reach the surface.

  Lymphatics have been described in the thyroid gland and in the thymus.
  The adrenal has a superficial plexus divided into two layers, one in the loose tissue about the gland and the other beneath the capsule. Capillaries have also been described within the parenchyma.
