Starling does not accept this view, and cannot regard as an article of faith Heidenhain's dictum that normally filtration plays no part in the formation of lymph.
The English starling is stated to be the only European bird to have thoroughly established itself in the colony.
They include, however, the snipe and military starling, which on account of its scarlet breast is locally known as the robin.
Heidenhain recognizes two classes, first, such substances as peptone, leech extract and crayfish extract; and, secondly, crystalloids such as sugar, salt, &c. Starling sees no reason to believe that members of either class act otherwise than by increasing the pressure in the capillaries or by injuring the endothelial wall.
It is known that several, perhaps very many, if not all glands have also the power of secreting substances to which Starling has given the name of "hormones."

There is a little bird, the size of a starling, with brown back striped with black, and white breast, which the Indians call yncahualpa; it utters a monotonous sound at each hour of the night.
The European starling (Sturnus vulgaris) is naturalized in New Zealand, Australia and to some extent in the United States.
- Extinct Starling of Reunion (Fregilupus varius), adapted from figures by Daubenton, Levaillant and others.
His results, so far, have been confirmed by Starling, who finds that the amount of lymph-flow from the thoracic duct is dependent upon difference in pressure.
