A number of questions will arise when all elements are arranged into one whole, but the most interesting problem appears to me to be the arrangement of groups of similar elements, such as those of iron, cerium, palladium and platinum since, in this case, elements close to each other in their nature also exhibit approximately the same atomic weights, a circumstance not to be observed in other rows, for in the latter similar elements possess different atomic weights.
