    except parasites, purify in some measures the air by removing from it carbonic acid, and replacing that poisonous gas with oxygen. The late Dr. W. D/Moore in a translation^ of various papers from Weitschrift fur Biologic, in reference to the connection between typhoid and the height of the underground water, states the con- clusions in reference to this point arrived at by Buhl:— ], The variation which takes place in the mortality from typhoid in Munich necessitates the assumption of a cooperating cause, sometimes assisting, sometimes counteracting, the specific cause of typhoid fever, and which must be considered as its quantitative side, as the basis of the extension and force of the disease.^ 2'. Of all elements in Munich accessible to investigation, the oscillations in the underground water especially exhibit relations, unmistakably indicating their connexion with the spread and violence of typhoid fever. . • u 3. So long as the underground water continues to rise, the number of fatal cases of typhoid fever steadily falls, and vice versa. Density of population has a very great influence on the state of the public health. Dr. Gairdner has investigated the relation between the density of the population and mortality in England. The following table shows the results of his inquiries :— Population on square mile. Death per 100 of the population. 56 106 15 16 144 71 149 182 202 220 324 485 1,216 1,262 18 19 20 21 22 23 24 25 2 064 o'qnn 27 and upwards. 2,900 The reports of Mr. Chadwick on the condition of the labourmg classes in 1842, the report of the Health of Towns Commission, 1844, and the annual reports of the three registrars-general ot the United Kingdom show clearly that every increase in the density of the population is attended with an increase m he death rate, and a diminution of the vital powers of the people The French sanitarians have long since directed attention to the fuct that the most vigorous and best developed recruits wei-e those furnished by the rural districts. I have noticed myself that he great majority of powerful men employed as porteis by the brewers, corn merchants, and steam-packet companies are country born and bred. ^ , -o • n^,.r,f,;] The reports of Mr. Simon, medical officer of the Privy Council, England, show that the death rate from phthisis (as well as frorn other causes) has greatly decreased in many towns ^^con^^f;^ of drainage operations.
