We are led to believe that some excitement exists in the process of fibrine production, and that inflammation, being a local disease, must result in increased fibrine production at the site of inflammation. Fibrine is naturally derived from intervascular spaces, which, in the presence of inflammation, must supply more than usual. This increased local production naturally leads to an increase in the circulation. Dr. Cappie objects to prevailing views on exudation, arguing that fibrine is the product of excessive tissue metamorphosis due to a modified nutritive process. This process is accompanied by increased heat, tension, and vascular excitement. He suggests that debilitating influences disrupt the circulation, favoring blood flow to the site of inflammation. Dr. Cappie's theory involves a constant antagonism in the body's circulation. The amount of blood an organ receives depends not only on the stimulus applied but also on the attraction at other parts of the body. The more vigorous the general nutrition, the harder it is to draw blood to a diseased part, while a weak state allows easier blood flow to a diseased area. The paper on inflammation is considered interesting and suggestive, though not heretical. The book is small but influential. The text describes a patient with persistent fever, enlarged liver and spleen, constipation, emaciation, and good mental condition. Diagnosis was difficult, as symptoms did not fit enteric fever or malaria. Blood tests for Malta fever and chronic suppurative conditions were negative. The patient's condition showed fever patterns with fluctuations in temperature, and after 30 days, the fever returned with similar features.We are led to believe that some excitement exists in the process of fibrine production, and that inflammation, being a local disease, must result in increased fibrine production at the site of inflammation.
