He wrote:—
“The evidence on the localising conditions of cholera given in the report of Dr. Sutherland points to the following as among the more prominent of the removable causes of zymotic disease.
“Open ditches as sewers. Want of sewers. Badly constructed sewers accumulating deposits and generating sewer gases.
“The pollution of the atmosphere in streets and within houses from untrapped drains, from sewer ventilating openings in streets, and from cesspools, whereby the air was contaminated and the sub-soil saturated with filth.
“Want of house drainage.
“The absence of any organised daily system of cleansing, and the consequent retention of house refuse in or near dwellings.
“Bad water, badly distributed. Unwholesome trades. Unwholesome vapours exhaled from the Thames. Cellar habitations.
“Neighbourhoods, the houses of which are closely packed together with narrow overcrowded streets, alleys and courts so constructed as to prevent ventilation. Houses structurally defective, filthy, unventilated, and overcrowded—absolutely unfit for human habitation.”
And several others which need not be here enumerated.
“Lastly, and applying to all these—multiplicity of local authorities, and the want of sufficient powers in such authorities to deal with these evils.”
