In flowing haemorrhoids the above mentioned remedies require to be principally employed.

§ 9. As regards the critical discharges from the bowels (critical diarrhoea), these ought never to be left unnoticed in the selection of a new remedy. It is impossible to point out with unerring certainty those remedies which will prove the most efficient in those various kinds of diarrhoea for which the organism may be predisposed by a variety of diseases, especially diseases of the abdominal organs. Nevertheless we will mention some of the principal remedies, reserving to us the privilege of speaking of them more in detail when we shall treat of the special treatment of diseases.

§ 10. The same remarks which we have offered on the critical diarrhoea, apply to the so-called critical vomiting. This change which is considered critical by allopathic physicians and which is ushered in by a dirty coating of the tongue and a tensive oppression in the praecordial region, by frequent eructations, inclination to vomit, nausea, great restlessness and anxiety, frequent shuddering and cold sweat, and an irregular and intermittent pulse, requires the employment of a specific remedy. This symptom occurring mostly in gastric, bilious, and pituitous affections, for which Nux, Bryon., Pulsat., Antim. crud., Colchicum, Hellebore, Platin., Secale corn., Cuprum, Veratr., Tart, emet., Ipec, Arseri., Asar., are the best remedies, it is not to be wondered that precisely those remedies should be so efficient in arresting the vomiting together with the disease.

§ 11. An increased secretion of mucus in the lungs after an inflammatory or catarrhal affection cannot always be prevented, even under the best treatment. That secretion is owing to the morbid condition of the mucous glands, occasioned by the previous inflammation. No matter what shape or colour the expectoration may assume, ball-shaped, thick, coherent, yellowish-white, or whether it be considered critical or otherwise, it will be necessary to remove it by suitable remedies, lest a chronic affection, weakness, etc., should be entailed upon the lungs or trachea, which must necessarily be the case if the expectoration is suffered to remain too long. Puls., Dulc, Squilla, Senega, Ipec, Bryon., Stannum, and others, are the principal agents for the removal of such an expectoration.

§ 12. Critical ptyalism is one of the least frequent phenomena occurring in fevers. It is seen in several kinds of typhoid fever, smallpox, rash or quinsy, and in other diseases where glandular organs are affected. The precursory symptoms of ptyalism are said to be pain behind the ears, difficulty of swallowing, confluence of saliva in the mouth, other excretions being suppressed for the time. Those symptoms indicate one of the following specifics: - Bellad., Hepar sulp., Sulphur, Mercurius, Dulcam., Acidum nitri., Tart, emet., Cantharides, and others.

The critical changes which have been enumerated in the preceding paragraphs may generally be considered favourable if they occur at a period of the fever which has the character of a critical period, if they are accompanied by an essential alleviation of the symptoms, or if they do not depress the vital energy; or lastly, if the critical reaction of the organism cannot be ascribed to other causes. Under homoeopathic treatment that critical commotion of the organism may be occasioned by too large a dose of the homoeopathic specific, and would not have occurred if the dose had not been too large.

§ 13. It is just as important for a homoeopathic as it is for an allopathic physician to know the general remote causes of fever; without that knowledge it is scarcely possible to establish a correct diagnosis, and to treat the disease successfully.

The exciting causes of fever are very various; constitution, sex, age, mode of life and occupation, the natural evolutions of the organism, may be such causes; physical exertions, injuries and wounds, internal inflammations, suppurations and ulcers, etc., may likewise occasion fever.

Fevers may be caused by external influences not depending upon any innate morbid disposition; such fevers are a kind of poisoning of the organism, and may be considered epidemic and contagious. Such external influences are:

(1.) The atmospheric air. In spring, for instance, when the weather is liable to sudden changes, and a warm atmosphere frequently alternates with rain, wind and cold, catarrhal and rheumatic fevers are predominant; in the summer, when the energy of the body is depressed by hot and sultry weather, and the digestive and assimilative powers are weakened, the organism is predisposed for bilious and gastric fevers; in the fall the sudden succession of warm days and cold nights predisposes man for pituitous, typhoid, putrid, and other kinds of dangerous fevers; in the winter season, fevers have generally an inflammatory character, occasioned by the cold, dry, raw, and cutting air. Epidemic malignant fevers generally cease in that season. An atmosphere filled with electricity, gases, and with the vapours arising from marshes, is likewise favourable to the occurrence and development of fevers. If the weather which generally prevails in the different seasons, deviate greatly from its usual state, the character of the fever is, of course, correspondingly modified. Lastly; fevers are more or less influenced by the stars, which affect organized bodies either directly or indirectly, by means of causes or conditions controlled by the influence of the heavenly bodies. The state of the weather, for instance, which has the greatest influence on the animal organism, is regulated by the heavenly bodies. Who does not know the influence of light, heat, sun and moon, upon all organic beings?

(2.) Contagia and Miasmata. Among these may be numbered poisonous influences arising from decaying plants and animals, exhalations of plants and animals in close rooms, becoming deleterious on account of not being replaced by fresh air. If one man in such rooms is attacked with fever, all the others are. It is an established-fact, that the first cases of fever are occasioned by the epidemic miasm; but in the patients who are first attacked with the epidemic fever, a contagious principle is afterwards engendered capable of propagating the disease, so that contagium and miasm support one another.
