One master-brewer died of cholera, being 1 in 160 of the trade; but no brewer’s man or brewer’s servant is mentioned as having died of this malady, although these men must constitute a very numerous body in London. There must be a few thousands of them. I have, indeed, met with the deaths of two or three of these persons, in looking over the returns of some of the most fatal weeks in 1849; but the brewers’ men seem to have suffered very slightly both in that and the more recent epidemics. The reason of this probably is, that they never drink water, and are therefore exempted from imbibing the cholera poison in that vehicle. The great prevalence of cholera along the course of rivers has been well known for a quarter of a century; and it meets with a satisfactory explanation from the mode of communication of the disease which I am inculcating. Rivers always receive the refuse of those living on the banks, and they nearly always supply, at the same time, the drinking water of the community so situated. It has sometimes been objected to the propagation of the disease by the water of rivers, that the epidemic travels as often against the stream as with it. The reply to this is, that people travel both against the stream and with it, and thus convey the malady from village to village and from town to town on the banks, whilst the water serves as a medium to propagate the disease amongst those living at each spot, and thus prevents it from dying out through not reaching fresh victims.
