glairin

noun

1. (archaic, uncountable)baregine

   “Berzelius supposes humus to contain humic acid, humin, crednic and apocrenic acid, and traces of glairin.”

   “The glairin is described by Thomson as a peculiar substance which has been observed in certain sulphureous mineral waters, and was first noticed by Vauquelin ( Ann. de Chim. XXXIX. 173) , who described several of its properties and considered it analogous to gelatin.”

   “He states that the glairin of the sulphuretted water of Aix, in Savoy, is white, but slightly soluble in water, and more soluble in concentrated acids, from which it may be precipitated in bluish-white flakes.”

   “The glairin or baregin found in almost all the hot sulphuretted waters of the Pyrenees, is a very complex substance, consisting of the remains of animal and vegetable matter, together with various inorganic substances, such as crystals of sulphur, iron pyrites, silica, &c.”
