(After Sauveur.) The alloy of such composition as to show but one point of solidification, the lowest one possible for any mixture of the metals concerned, is known as the eutectic alloy. From any other mixture the metal which is in excess crystallizes out first until the proper proportions are reached for the formation of the eutectic. Similar phe- nomena are manifest in ordinary solutions, and the solu- tion of such strength as to show a single minimum freezing- point is called the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Winslow, C. -E.
