Whether a bird excavates its nest in earth or wood, or weaves or plasters it, the work is all done by means of two straight pieces of horn the bill. There is, however, one useful substance which aids the bird the saliva which is formed in the mucous glands of the mouth.
Dodd took them out of her desk and spread them earnestly. He ran his eye over them, and pointed out that the mucous-membrane man and the nerve man had prescribed the same medicine, on irreconcilable grounds; and a medicine, moreover, whose effect on the nerves was nil, and on the mucous membrane was not to soothe it, but plough it and harrow it; "and did not that open her eyes?"
Among the local factors concerned in the development of tumours, reference must be made to the influence of irritation. This is probably an important agent in the causation of many of the tumours met with in the skin and in mucous membranes for example, cancer of the skin, of the lip, and of the tongue.

In a short time the mucous membrane relaxes again and then the discharge is re-established.
Hooping-cough in itself is not inflammatory, it is purely spasmodic; but it is generally accompanied with more or less of bronchitis inflammation of the mucous membrane of the bronchial tubes on which account it is necessary, in all cases of hooping-cough, to consult a medical man, that he may watch the progress of the disease and nip inflammation in the bud.
By the first stage of the cold I mean that condition which obtains before the stage of secretion is arrived at, where the mucous membrane is being congested, where it is almost impossible to distinguish what is the highest point of normal stimulation under which the membrane may be expected to do its best work.
The bleeding occurs as an oozing, which may be comparatively slight and unimportant, or by its persistence may become serious. It takes place into the superficial layers of the skin, from mucous membranes, and into the substance of such organs as the pancreas.
