From the mortuary registries it appears that the average duration of life among the professional persons and gentry in the city of London, who live in better cleansed and ventilated houses, and better cleansed streets, is, on the average of the whole class, about 43 years, and 6 per cent. of the deaths are deaths from epidemic disease; whilst among the labouring classes the proportion of deaths from epidemic disease is 19 per cent., and the average age of all who die is only 22 years. With such sanitary regulations as are under the public control of the public authorities, to what extent do you think it probable the duration of life amongst the labouring classes may be extended?—So far as I can judge, without examination of the particular cases, I should say that the average might be extended one-half at the least.

The majority of the cases of epidemic diseases may decidedly be ascribed to the want of cleanliness and ventilation. On looking over the mortuary registry of the deaths occurring in Upper Thames-street and the district attached to it, I find the causes of death most frequently registered are “low fever,” “low fever,” occurring one after the other. This recurrence of low fever corresponds with my experience of sickness, which so often assumes the character of low typhoid nervous depression. The medicine I use in the greatest quantity is ammonia, as an active diffusive stimulus. For all classes this medicine is in constant use. In damp weather we have always much increase of this illness: the dampness produces a depression which lays them open to the atmospheric poison.

Have you had instances where better cleansing has taken place and illness diminished?—Yes; for example, in Ireland-yard, containing a large number of families of coal-heavers and others, a place which I never was out of from continued illnesses: the yard has been much better cleansed, the houses put in better order, and now there is very little illness there. I know for a fact, that in the neighbourhood of London-wall, where recently great improvements have taken place in the sewerage and ventilation, disease has greatly diminished, especially low fever. Formerly they had a sewer which used to be stopped up and overflowed; they have had of late a new sewer, which now works better; they have no stink or stench in the kitchens, as formerly, and they have nothing of the same kind of disease going on there that they used to have before.

Are the houses in Ireland-yard occupied by the same inhabitants?—Just by the same class. The habits of coal-heavers are reputed to be none of the best in respect to general cleanliness or temperance.

Have you observed any alteration in their habits?—Not in the least.

Have you observed what is the personal condition of the natives of London?—The real cockney is generally of stunted growth.

Have you observed whether the children born in London of parents who have come from the rural districts are as tall or as strong as the parents?—Generally shorter children, though some of them are as tall, but all are of comparatively weakly constitutions; they are particularly predisposed to strumous disease. I have been so impressed with the effect of children living in a London atmosphere, that I have been anxious to send them out of it when possible.

Does not defective cleansing, as causing atmospheric impurity, not only tend to produce disease and shorten the duration of life, but depress the physical condition of the population?—Decidedly.
