Excerpt from The Causes and Prevention of Phthisis Fifthly, he speaks of the propagation of tubercular disease, and especially of tubercular consumption, by contagious transmissibility.' And lastly, though incidentally, he adverts to the necessity 'of more diligent and continued attention to the study of the accurate geography of diseases, together with the exact chronology of the appearance and per sistence of those diseases which are of only occasional and temporary occurrence, and also the exact date of each epidemic prevalence, or extra severity of the ordinary endemic maladies in different countries and localities.' In the following lectures, each of these suggestions is considered in its turn, and an attempt is made to bring the subject in line with the most recent researches respecting the causes of tuberculosis, and the modes in which it may most readily be prevented. Some slight changes in the exact arrangement of the lectures have been made, but they are now published in' form and substance practically as they were delivered.
