 the magistrates of the quarter sessions, and act under

Dr. Percival had written elsewhere, * It has been found, 

 by experiment, that the fumes emitted by almost every 

 species of burning fuel are fatal to animals, when applied 

 in a sufficiently concentrated state. I have computed that 

 three hundred tons of coal are every day consumed in the 

 winter season at Manchester. The factitious gas generated 

 by its combustion must amount at least to one-third of this 

 quantity ; it is probable that the smoke proceeding from it 

 constitutes another third part, and both together are 

 capable of occupying a space of very wide extent. Now if 

 it were not for the dispersion of these vapours by wind, the 

 precipitation of them by rain, and the influence of other 

 causes, which restore salubrity to the . air, respiration could 

 not be carried on under such circumstances. And we may 

 observe that frosty weather, which is generally serene and 

 without wind, always proves extremely oppressive, and 

 sometimes even fatal to asthmatic patients in great cities. 

 Indeed the rate of human mortality bears a pretty near 

 proportion to their magnitude and population ; and I have
