Some authorities, especially those in America, strongly recommend the internal adminis- tration of cubebs, which may be used in one or other of the formulae given in the Appendix (Formse. XXV. to XXVII.) (ii) Vascular Collapse of the Erectile Tissue. In most cases where, the middle turbinated body being normal in size and the olfactory fissure not unnaturally wide, we can obtain through the anterior nares a view of the posterior wall of the naso-pharyngeal cavity, we Collapse of may conclude that the erectile tissue is in a greater or tissue* ^ess degree of collapse. This may be temporary or permanent. In the latter case, the condition is productive of various symptoms, the result of the imperfect moistening of the inspired air. We find, for instance, a tendency to pharyngitis sicca: the posterior wall of the naso-pharynx, being the first moist surface upon which the dry air impinges, gives up its water and becomes coated with a film of inspissated mucus. Indeed, this condition of the nose is found in most cases where the posterior wall is dry. Special emphasis must be laid upon the fact that we never find the nose and pharynx thus affected without more or less laryngitis : a point that will be further developed when we consider rhinitis sicca. This collapse of the erectile tissue may be a symp- tom of either catarrhal or dry rhinitis, subacute or chronic. We perceive sometimes, after direct exposure to irritative agents, especially a yellow fog, super- saturated though it is with aqueous vapour, a tend- ency to dryness of the mucous membrane. Yet Sometimes although this condition of collapse is found as a symp- a symptom tom 0f guc]1 various affections, it is, when once of antenna ' ' developed, little given to variation in degree, and little](https://iiif.wellcomecollection.org/image/b21014875_0094.jp2/full/800%2C/0/default.jpg)
