![floor, the other is made of timber. The author knew a family of this class who occupied a house of this description. The members of it were frequently affected with illness. They were scarcely ever well. By recommendation they went to a house with wooden floors, where they became speedily well, and, so long as they continued in this habitation, they required no medical aid. For some reason or other, they were obliged to go again to a house with a stone floor, when their former tendency to become ill returned, and so far as is known to the author, they continued so as long as they remained in it. In another case a house was occupied by three individuals, and it was provided with this kind of floor in that apartment which was most occupied by the family. The people had remained in it for some years, and during that period they suffered very much from various ailments. The author at once attributed this tendency to become unwell to the abstracting power of the stone floor. The proprietor of the house having been induced to place a wooden floor over the stones, the health of the inmates has been better ever since, and they are now satisfied that the favourable change has taken place in conse- quence of the super-position of timber on the stone. The reason of this difference between stone and wood, when used as floors, is very apparent on these principles. The stones are much better conductors of electricity than wood. There is little need to multiply examples of this mischievous peculiarity of stone floors, as facts of the same kind must frequent]}* pass under the observation of any one who has an opportunity of looking at them as they pass before him.](https://iiif.wellcomecollection.org/image/b21308871_0420.jp2/full/800%2C/0/default.jpg)
