The first important work on tropical diseases. Only six copies of the original edition of this book are known. It includes full accounts of malaria, typhoid, and scurvy, and the first accurate descriptions of yellow fever, amoebic hepatitis, dracontiasis, trichuriasis, and tungiasis. Abreu's description of scurvy was remarkably precise. He treated the disease with fresh milk and antiscorbutic syrups, particularly rose syrup- a rich natural source of ascorbic acid. For a study of the book see F. Guerra, Clio Medica, 1968, 1, 59-60. Digital facsimile from Google Books at this link.
