Abstract

A specimen of the rock of which the Houses of Parliament, London, are constructed was sent us some months ago, for analysis, by the Honorable John Burns, member of the British Cabinet. We had read in one of the popular magazines that the rock in the Parliament buildings is quite rapidly weathering and crumbling. We desired to make the chemical analysis to ascertain, if possible, the reason for the decay. The rock has a buff color when first quarried or on a fresh fracture, but it is darkened by the London smoke except in some of the protected angles. The smoke is so thick on the rock that it can easily be rubbed off with a piece of paper, or a handkerchief, as we tested in many places throughout the building.
