important. The farther we drifted from the plateau of Vila Rica and Tejuco to the north, the more frankly the diseases of the abdominal rather than the chest-rheumatic features were common. As a general disposition for intestinal diseases, one should consider a certain weakness of the digestion, which in the backcountry is often indicated by the lack of appetite or voracity, by the ameliorated heartburn and indigestion, needing gauze and eructation, which constitute more disease than lack of education.
This weakness must be attributed to the coarse diet of beans, corn, cassava and bacon, bad water, and poor quality cachaca, the hot climate and sexual excesses, and thus develops into various diseases. Numerous skin diseases first appear as a result of these disturbed digestions, and in fact, scabies, the simplest manifestation of this state, should be considered. These skin diseases take a bad character, getting especially complicated with extreme syphilitic dyscrasia. The diversity of the forms and the prognosis of such a state are extraordinary, and many of the common diseases here are almost unknown in Europe, or else they come in exceptionally rare forms. I observed: light red pustulas, which bulge at the top, and leave a small shallow scar; bluish-red veins, which crack and sometimes burst, producing ugly ulcers; yellowish, lymph-filled blisters of the genus pemphigus without inflamed aureole; warts on all parts of the body; abnormal skin callosities of pale or yellowish color, especially on the feet, ankles, toes and hands; They result in dissorating ulcers, extremely painful, and finally, in the cellular context, widely scattered under the skin, sometimes on the joints, most commonly on the feet. To all these phenomena of corrupted skin, Brazilians usually designate with the general name of scurvy, a less incisive expression than syphilis.

As common as skin disorders, are those of the glandular system. I noticed swelling of the inguinal gland, mesaraica, pancreas, and liver, which forms imperceptibly, without previous disease, sometimes as a consequence of severe chronic inflammation or endemic sessions. Symptoms of apepsia, chills alternating with transient heat, expectorating to viscous humors and saliva, which is commonly called choking, are often indications of such inflammations and more dangerous, as they often indicate when large disturbances already exist in the body like infarction of the glands, esophagus or intestines. As for intermittent fevers, sometimes they appear in daytime, sometimes on Tuesdays or Wednesdays. In the Sao Francisco River, where fevers are endemic with a great disposition for them; they are already motivated by an abundant meal, the use of fresh meat, instead of the usual dry or salt meat. Eating fruits at night is always dangerous. It is not just the excellent, fresh watermelons, but also the oranges, for which there is a proverb: "Orange at dawn is gold; at noon is silver; at night it kills." Only mango, which has a lot of balsamic resin, seems not to be harmful even at night, and fresh fish is eaten at night without fear. Pathogenic conditions of the sections or malaria may, moreover, result from chronic inflammation of the liver. Hence the rapid formation of the so-called "bacchus", usually formed generally in the left lobe of the liver, and often reaches such size that it compresses the entire hypochondria. Rarely, these consequences of fever are completely cureable, and they are the causes of hydrops or ethical fever, causing the patient's death. Moreover, are the causes for malignant fevers or putrid fever, so for the slightest reason, such as rapid change of temperature, continuous cold or humidity, the attacked person does not resist. The inhabitants, who, unfortunately, lack medical and therapeutic knowledge, try to treat intermittent fevers, especially with vomiting of ipecacuanha and emetic tartar. In such remedies they have such unconditional confidence that, after 20 or 30 failed attempts, they refrain from any other vomiting, and let the disease heal itself.

Cinchona, Peruvian bark ?

The use of Peruvian bark is not as general as it deserves. The reason is that they may not know how to apply it in a timely manner and in the proper dose. They complain about it, saying that it raises the fever and produces scabies. Also not so many employed
