Cocculus and Belladonna deserve a particular mention in the treatment of this class of fevers. Cocculus is especially adapted to gastric-bilious fevers which arise among other causes from chagrin and abuse of chamomile, and are aggravated after every eating and drinking, sleeping, talking, smoking, coffee; the aggravation frequently amounts to a fainting fit, after which great debility and trembling of the limbs remain. The fever consists principally in a sudden, pretty violent flush, with thirst, small, hard pulse, cold feet, and excessive sensitiveness of feeling. The gastric symptoms are: change of taste, aversion to food or drink, with heat and redness of the face, frequent bitter eructations followed by hickup, oppression at the stomach, and pain in the hypochondria; constipation. Both Cocculus and Bellad. are particulary adapted in such fevers to children and females. Belladonna is particularly useful when the fever occurs after a cold, in lymphatic and scrofulous subjects. The fever itself is a violent burning heat, with strong, quick pulse, great thirst, profuse dark urine, the sleep is disturbed by frightful dreams; the mind is agitated, the blood rushes to the head, which aches intensely, the cheeks are hot and red. These symptoms are frequently accompanied by a slimy and bilious vomiting, a burning, griping tearing in the umbilical region, and frequent but ineffectual urging for stool.

§ 47. In robust and plethoric young individuals the febrile phenomena are sometimes very strongly marked and intense, requiring the exhibition of Aconite, which is so much more advisable as Aconite has proved a specific against the consequences of fright, anger, chagrin, especially when the circulation and the functions of the liver were disturbed by those causes. Aconite is particularly indicated by violent chills followed by a general dry and burning heat, hard, full, bounding, accelerated pulse, great thirst, and a general profuse sweat succeeding after the heat.

If typhoid symptoms should set in, or if the fever should become a real typhus, the remedies which will be more particularly described in the chapter on typhus, such as Bryonia, Belladonna, Rhus tox., Phosphorus, Arsenic, etc., require to be used. Arsenic is suitable even in purely gastric fevers when the following symptoms are present: blackish, diarrhoeic stools, accompanied with violent colic, vomiting, great internal burning heat, dry lips and tongue, unquenchable thirst, excessive debility and prostration, great anguish, nightly restlessness, burning and beating in all the blood-vessels, clammy sweats, apoplectic symptoms.

The diet requires to be carefully regulated, of course. However, errors in diet need scarcely to be apprehended, as the patients have an aversion to food, especially warm food. The best beverage is fresh water, in a very few cases some other drink may be given.

§ 48. Mucous fevers, erethism of the mucous membrane of the intestinal canal.

This fever is essentially a catarrhal affection of the greater portion of the mucous membrane of the chylo-poetic canal; sometimes the mucous membranes of the other systems and organs are likewise affected. The precursory symptoms which sometimes set in a long while before the fever breaks out, are: loss of appetite, flat taste or entire absence of taste, white slimy coating of the tongue, loathing, great repletion of the stomach, irregular evacuations, pale countenance and debility, and other symptoms which have already been mentioned among the precursory symptoms of gastric fever. All those phenomena are generally mild, sometimes the patient feeling rather comfortable, chilly. As a general rule the development of the disease takes place in a concealed manner, the symptoms have a mild character and the disease is on that account, easily neglected and overlooked. As the disease proceeds, the patient throws up a tasteless white mucus, the stomach is distended by the introduction of the least quantity of food, a tension and pressure being experienced at the same time; the tongue which had been so far covered uniformly with a white mucus, now becomes dark-red at the tip and on the edges, which indicates the setting in of a typhoid condition. On the other hand we sometimes see the tongue remain white during the whole course of the disease, but it becomes dry especially in the evening; the taste is unpleasant, with sensation as if the mouth were filled with mucus, which is sometimes visible and lines the mouth and palate like glue; in the morning long threads of a thick, tenacious mucus are either hawked or gagged up. The bowels are generally slow or confined; only when the affection spreads over the mucous membrane of the lesser intestines, the patients have from two to six stools a-day, accompanied with rumbling and pinching, the discharges consisting in white, jelly-like thready mucus. mixed with undigested food, the colouring matter of bile and pieces of worms; the urine is straw-coloured, loamy, flocculent, and depositing a whitish sediment. In the commencement the fever has distinct remissions which afterwards become almost imperceptible, the pulse is seldom frequent, rather soft, more so than full and irritated; thirst and sweat are moderate, sometimes however the patient has a great desire for drink, the skin is slightly warm, the patient feels weak. Drowsiness, aching of the forehead, restless night sleep, dim eyes without lustre are almost constantly present, the patient is generally indifferent, peevish, in a state of apathy.

§ 49..The mucous fever which is frequently confounded with gastric fever and typhus, is sufficiently characterized by the peculiar symptoms of the mucous membranes which make their appearance in the very commencement of the disease, by the copious secretion of a tenacious, albuminous, thready mucus, by the coating and the peculiar colour of the tongue, by the mildness of the fever, with a pulse which is but slightly or not at all accelerated, and by the absence of pain in the ileo-coecal region, of the characteristic typhus evacuations from the bowels, of enlargement of the spleen, etc.
