its prevalence, as well as to arrest its course when already formed, by due attention to the comfort of the laboring population, both in their dwellings and in the pursuit of their occupations.” (4 International Cyclopaedia, 286.)
“ Particular occupations predispose (to consumption), especially such as occasion constant inhalation of small particles.” (2 Johnson Cyclopaedia, 488.)
“ Thus tailors, seamstresses and similar workers are especially prone to the disease. More especially is this true of occupations whose performance necessitates the inhalation of dust particles. The dust particles act as irritants of the
fine structures which line the air passages and vessels, inducing chronic changes, which, in turn, are liable to lead to consumption.” (3 Chambers Encyclopaedia, 438.)
“ The bacillus of tuberculosis finds, indeed, the most favorable conditions for its existence in the squalor of congested slums, in the foul atmosphere of dusty workshops, in close courts, alleys, etc.” (70 Fortnightly Review, 308.)
“A very large number of the most efficient workmen employed in quarries, metal works, cotton and wool manufactories, print trades and many other occupations exposing them to bad air and dust fall victims to this infection.” (194 Edinburgh Review, 444.)
“ Since statistics still show that the mortality from Phthisis in people who follow certain trades is much greater than in others, there can be no doubt of the causal relationship between occupation and pulmonary disease and of dust being the causa causa/ns. In 1866 it was demonstrated that ■ two kinds of occupation had long been recognized as hurtful, viz.: 1, those that give rise to mechanical or chemical irritation of the air passages by dust, grit or fluff being diffused through the atmosphere; 2, those in which the operatives are exposed to abrup>t changes of temperature.” (The Lancet, vol. 165, p. 1345.)
“ Living in a close atmosphere and in a high temperature, bakers are subject to lung diseases, more especially phthisis.” (5 Reference Handbook of Medical Science, 276.)
