§ 36. It is observed by some of the witnesses that usually, and except by accident, and in few cases, the miasma from the remains of the dead in grave-yards can only reach the living in a state of diffusion and dilution; and that large proportions of it probably escape without producing any immediately appreciable evil. The practice, however, of the retention of the remains in the one room of the living brings the effluvium to bear directly upon the survivors when it is most dangerous, when they are usually exhausted bodily by watching, and depressed mentally by anxiety and grief—circumstances which it is well known greatly increase the danger of contagion. The males of the working-classes in general die earlier than the females, and in the greater number of cases the last duties fall to the widow; and the prevalence of fatal disease chiefly amongst the children is frequently attributed to the circumstance, that she is aroused from the stunning effect of the bereavement by the necessity of going abroad and seeking pecuniary aid, and making arrangements for the funeral, whilst the children are left at home in the house with the corpse. In Scotland, from an aversion to sleeping in the presence of the corpse, it is the practice to sit up with it, and there is then much drinking of ardent spirits. Mr. W. Dyce Guthrie speaks strongly of the evils attendant upon the practice of the unguarded retention of the body under such circumstances, and of the instances known by himself where persons have come from a distance to attend the funeral of a departed friend, and have returned infected with a disease similar to that which terminated the friend’s existence. The concurrent and decided opinion of himself and a number of other medical witnesses is, that the public health is much more affected by the pestiferous influence of the corpse during the interval of time that occurs from the moment of death, up to the hour of the funeral, than it commonly is or can be after interment. § 37. Of the deaths which take place in the metropolis, it will be seen that more than one-half are the deaths of the labouring classes. The following table, taken from the Mortuary Registries during the year 1839, shows the numbers of deaths amongst the chief classes of society, and the proportions of deaths from epidemic diseases. At least four out of five of the deaths of the labouring classes, it will be remembered, are stated to occur in the single living and sleeping room, that is to say, upwards of 20,000 annually.
