Excerpt from Geographical Pathology: An Inquiry Into the Geographical Distribution of Infective and Climatic Diseases The object of this work is to sketch the geographical distribution of infective and climatic diseases, and to trace the influence of temperature, rainfall, altitude, and soil - conditions on their prevalence, character, and epidemic spread. Uuder the term infective diseases, I include miasmatic diseases, such as malaria; miasmatic-contagious maladies, such as cholera; and the contagious diseases proper, such as scarlet fever.1 Climatic diseases include, amongst others, croup, bronchitis, pneumonia, and rheumatism, which are either owing to, or are materially influenced by, meteorological conditions. Organic diseases of the heart, kidneys, and nervous system, which are not, as a rule, caused by infection, and are not materially It seems to be necessary to define more precisely the sense in which I employ these terms: - The terms miasm and malaria arc not used in their etymological significance. By miasm is to be understood an infectious principle, whether organised or toxic in its nature, developing in, and derived from, the soil or other local surroundings of man,- even although the disease caused by such infectious principle may be communicable from man to man by inoculation. Recent experiments seem to show that malarial fever is capable of being thus communicated, but it is not the less a miasmatic disease in the sense which we have defined. By malaria, I mean the hitherto undiscovered cause of intermittent fever and of the other forms of fever and constitutional disturbuuec due to the same infection. Malaria is a typical miasmatic disease; but there arc other miasms besides malaria, and miasmatic fevers other than those of malarious origin. A miasmatic-contagious disease i3 one due to an infectious principle which is derived from the body of a person or animal suffering from it, hut which is capable, not only ol maintaining itself for a time, but ato of developing or multiplying in the soil, water, food, or other substrata. This docs not exclude the possibility of the more or less direct transference of the infective principle from the sick to the healthy. The infective agents of the class of true contagions diseases may adhere to clothes, walls, furniture, soil, or articles of food, but arc uot supposed to undergo any change, or even to multiply outside the body. It may, however, be ultimately proved that some of those diseases, which are at present regarded as contagious, are ready miasmatic-contagious maladies.
