Page 241 - The quantities of different elements or groups of elements liberated by the same quantity of electricity are proportional to their equivalent weights.
Page 534 - The alloy of iron and nickel known as "invar" is called a steel. Invar containing 36 per cent of nickel is practically without expansion or contraction when exposed to varying temperatures. It is used for scientific instruments, pendulums, and steel tapes. An alloy of 25 per cent nickel and 75 per cent copper is used in the 5-cent piece or " nickel
Page 543 - ... class have much in common, and we might therefore expect the physical as well as the chemical properties of the atoms to have a general resemblance to each other. This property is, I think, analogous to that indicated by the periodic law in chemistry. We know that if we arrange the elements in the order of their atomic weights, then, as we proceed in the direction of increasing atomic weight, we come across an element, say lithium, with a certain property ; we go on and after passing many elements...
