“Such is the explanation which I have to offer regarding much of the misery now prevalent, and it is the explanation invariably given by the economical working classes themselves when questioned on the subject. Heads of families, having three or four children, whose incomes average from 14_s._ to 18_s._ per week, have assured me that a man with a wife and three or four children can live comfortably on 12_s._ or 14_s._ a-week; and they generally account for the misery and destitution existing among families by saying, that many who have good wages reduce themselves to poverty and deprive themselves of sufficient food and clothing by their mismanagement, want of frugality, and drinking practices. Cases of waste and dissipation have been related to me, where the husband having gone to the tippling-house to enjoy his glass and his friend, the wife, knowing this, sent for her bottle and her friend, and enjoyed herself at home. A single visit to one of these spendthrift families, who are in the receipt of good wages, would convince any one that their persons and houses might be far more orderly, clean, and comfortable, were they but half trained to the tastes and habits of household industry, sobriety, and economy.” The more closely the investigation as to the causes of epidemic disease is carried the more have the grounds been narrowed on which any presumption can be raised that it is generally occasioned by extreme indigence, or that it could be made generally to disappear simply by grants of money. In the great mass of cases in every part of the country, in the rural districts and in the places of commercial pressure, the attacks of disease are upon those in full employment, the attack of fever precedes the destitution, not the destitution the disease. There is strong evidence of the existence of a large class of persons in severe penury in some places, as in Glasgow, being subject to fever, but the fever patients did not, as a class, present evidence of being in destitution in any of the places we examined. _Dr. William Davidson_, the senior physician of the Glasgow Royal Infirmary, who has written a Treatise on the Sources and Propagation of Continued Fevers, for which the prize instituted by Dr. Thackeray, of Chester, was unanimously awarded at the annual meeting of the Provincial Medical and Surgical Association, states in that treatise, when speaking of the influence of delicacy of constitution as a predisposing cause of fever,— “We have kept a record of the physical habit of the patients admitted into the Glasgow Fever Hospital from May 1st to November 1st, 1839, and the following were the divisions adopted:— “1. Moderate, by which is meant a person having an ordinary quantity of muscle and cellular substance. “2. Full or plethoric, having an extra quantity of adipose texture or of blood. “3. Muscular. “4. Spare. “5. Emaciated or unhealthy in appearance.
