The people amongst whom I practise generally occupy one room where they live in, and a bed-room above; but I have known many instances of a family, say a man, his wife, and from three to six children, having only one bed and one apartment for all purposes. But a great many dwellings there consist of only one room, and in many of the lodging-houses I have seen five or six beds in one small room, in which it has been acknowledged that from 12 to 14 persons have passed the night, and the air has been so bad that I have been compelled to stand at the window whilst visiting the patient. He also states, that— He has seen many deaths take place in such houses when the body remains in the bed where it died; and I have known it remain two or three nights before interment. In Irish cases they keep them longer. I have seen a child lie in a down-stairs room in a corner, dead of small-pox, and another dying, and the house full of lodgers eating their meals. The length of time that a corpse is kept varies very much according to the disposition of the relatives and the means of procuring a burial, as there are no restrictions as to the length of time bodies are to be kept. I have observed, that in cases of small-pox disease frequently follows in rapid succession on different members of the same family. I have frequently known cases of a low typhoid character arise where many persons sleep in the same room: the addition of a death from any such cause of course increases the danger to the living. In Manchester and in several northern districts, it appears that by custom the corpse seldom remains unburied more than three or four days, but during that time it remains in the crowded rooms of the living of the labouring classes. Every day’s retention of the corpse is to be considered an aggravation of the evil; but the evidence is to be borne in mind that the miasma from the dead is more dangerous immediately after death, or during the first and second day, than towards the end of the week. In a proportion of cases decomposition has commenced before the vital functions have ceased; immediately after death decomposition often proceeds with excessive rapidity in the crowded rooms, which have then commonly larger fires than usual.
