[The gastric mucus of domestic animals].

The gastric mucus of different domestic mammals shows a certain pattern of reactions which is typical for the species but not for the respective gland. There is no "mucoid" as an uniform specific mucus substance and a greater plurality in the composition of the secretions as it is reflected by the classification in acid and neutral mucins. A classification of the glands as to the secretion is problematical and further consideration is necessary.
