Unanimity on this point is no doubt highty desirable among chemists of all nations; but the change ought to proceed from some general congress of chemists, and should not be attempted by individuals. The student should bear in mind, in reading foreign works, that the atomic weights of hydrogen, chlorine, bromine, iodine, cyan- ogen and nitrogen, adopted on the Continent, are only half as high as those used in England; so that, for example, water, with us, is represented by HO, while, in France and Germany, it is H,O ; chloride of potassium, which in England is KCl, on the Continent is KCI, ; and so on. Finally, the Editor has to apologise for the errors and imper- fections of the work. ‘Those who are best acquainted with the rapid and incessant progress of the science, will be most ready to excuse them ; and those who best know its extent, will best appre- ciate the difficulties which must attend any attempt to compress into one volume, however large, an accurate or practically useful account of Modern Chemistry. WILLIAM GREGORY. King’s College, Aberdeen, October 20th, 1842.
